Toontown: Corporate Clash | Volunteer/unpaid position | Remote only (worldwide) | All experience level welcome

We are Toontown: Corporate Clash, an entirely not-for-profit MMORPG that is a fan reimagination of Disney's defunct MMORPG, Toontown Online. Besides continuing the legacy of Toontown Online and bringing the MMO into the 21st Century, we also use our original IP to [raise funds for charities](https://corporateclash.net/news/article/155) - we have raised over $54K for children's health and LGBTQ+ charities.

We are on the lookout for a broad range of talents, from Tech to Art to Community Management! Everybody on the team is a volunteer - there is no salary, we do not solicit donations and all expenses are funded by our staff. We pride ourselves as being a training ground for up-and-coming talent to gain experience working on a real product in a 100+ strong team; some of our volunteers have used their experience with us to land jobs in and out of the industry.

We have lots of interesting tech problems that arises from building on top of a 20+ year old codebase (yes, Toontown development started out on Python 2.0!). We are especially interested in people with an interest in distributed systems, system administration, game physics and automation pipelines!

Our Tech Stack is varied: Python for the game, C++ for distributed networking services, JavaScript / TypeScript and some PHP for web. We're working on modernizing our tech stack to migrate away from PHP, and looking to introduce Rust (for Tauri / core networking) into our stack.

You can see all of our positions and how to apply here (when emailing us, feel free to say HN): https://corporateclash.net/help/apply

How much you want to contribute is up to you; our volunteers typically contribute 5-10 hours a week.

NOTE: You can ignore the 3-month in-game activity requirement, it's being revised soon!

I love what you're doing and was going to submit for the PM role. I'm having an issue with the 'Application' part -- doesn't seem to be loading the form!

Hey Kyle, sorry about that! It’s working for me here if you want to try: https://goodparty.org/work-with-us/f3ef6b7e-b554-42a7-8fd2-9...

You can also email Danny from our hiring team danny.marcano [at] goodparty.org

Hi, I sent out an email but it failed to deliver to danny.marcano [at] goodparty.org. I also tried without the period, but it still failed. Do you have another good email contact?

Thanks for following up! Will connect via email..

Unable to apply as I'm based in Singapore- but software for political candidates was not what I had in mind! Super cool- if you could wave a wand, is there any other platform or product that you think can help the US political system?

One that comes to mind is a participatory budgeting game much like SimCity. The game let locals to actually do their own budgets based on local info. Some much economically can be optimized if all locals knows about how the money are spend.

Of course something like that would really take control out of hands of ones on top at the budget committees in DC and fees for their friends.

Decentralization will generate much much more wealth for most people, but it will take control away from a few that are in control.

Great to see modern approaches to politics.

One question though - why tableau? It's legacy now

Results matter more than the tools, so maybe there's an opportunity to help us move forward in that area.

its usually signature drives to get on ballots, getting media coverage, getting into debates, and general fundraising that are locking the third parties out... i would tackle the media coverage + fundraising angles first.

Drone startup | Product Engineer (Typescript) | 1 day/week in the office (London, UK) | Citizens of the UNITED KINGDOM only

You'd be working with engineers who previously worked at Google, Amazon, Helsing, Darktrace and an F1 team. We build drones (software and hardware)

We're looking for engineers that straddle real world problems, and use technology as a solution. We prefer personal projects or relevant hobbies, not hard leetcode questions. We value collaboration: pair programming, discussing, teaching and learning from others. We're looking for mission-driven engineers. People who see problems in the world and want to help solve them.

You'd be working with me to build the most intuitive, performant, and modern mission planning and flight monitoring software for drones, and related applications (tools for drone design and manufacturing). For my project, we use React, Tailwind, Node, drizzle-orm, Postgres, SQLite, deck.gl, Python, FastAPI, asyncio, and more. You're allowed (and compensated) to use AI services.

Because we are a small team, you will be noticed and rewarded for performance.

*Please don’t apply if any of these resonate:*

• You prefer narrow ownership—“I only touch the backend or the code I've written”.

• You think it's more about "who you know, not what you know".

• You haven’t actively learned a new tool or hobby in the last year.

If interested, email my temporary email: hn-june25@mail.orth.uk with your CV and some personalised information about why you'd be the right fit.

IIUC, an early technical employee was Argentinian and caused our engineering department to largely be built up in Cordoba. There's a sizable office down here!

Another argentinian here, nice username! :P

To both of you folks, if you think you or someone in your network would be a fit for the open position please do apply. You can send me a note as well, but it isn't required.

New Hedge fund | Sr/Staff Frontend Engineer | On-site (NYC)

We are a new discretionary, tech industry focused hedge fund, founded by a portfolio manager with 15+ years of experience at a Tiger Cub. I lead the data/technology team here and previously spent ~6 years in a similar role at a well known Tiger Cub.

We are hiring for a frontend senior/staff engineer for our internal research management web application.

Our tech stack: * Frontend: Typescript, Vue3 * Backend: Cloudflare, Supabase/Postgresql, Typescript *

Obviously, we are not the only ones trying to figure out how to use AI in investing but in a world where there are lots of people trying to build picks & shovels, this is an opportunity to be one of the goldminers at a greenfield, new firm. This role makes sense for people who are interested in finance/investing (although you do not necessarily have to have experience in the industry).

We're in full-time in office in NYC, so that's a requirement for FTE. We are potentially open to exceptional contractors located remotely.

We work very hard, hours are long, and people are very dedicated to the mission. It is not for everyone, but for those interested in competing in financial markets, love startup atmosphere without near-term existential risk, and want to work with super smart colleagues (both technical and investors!), this could be a great fit.

Target salary 180-250K, depending on experience + Bonus/Carry (hedge fund equity equivalent)

Contact: ai@nx1.com , I'm Alex.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

PostHog | Full-Time | Product engineers, Clickhouse engineer, Technical AEs | REMOTE (all remote) | Hiring GMT-8 to GMT+1

PostHog helps engineers build better products by combining product analytics, feature flags, session replay, a data warehouse, CDP and many more.

* open source, building a dev tool. We have a public handbook (posthog.com/handbook) if you want to learn how we work, pay and more in complete detail.

* we are growing through more autonomy and transparency not through process.

* we have a ton of scale and a bunch of super interesting technical problems to solve

* we're building 20 more products over the next couple of years, so you could end up building one of those

* we need: product engineers, a cracked clickhouse engineer to help automate and run our PB scale clickhouse cluster, technical account executives and technical customer success managers.

posthog.com/careers

As someone who has been preaching product engineer role for years, I would love to actually get a human response from PostHog one day and interview. either way, glad you all do so much work to spread the word about product engineer role

Regarding the applied product engineer role, will you consider hiring a contractor from China?

It says "Remote (US, UK, EMEA)" so the answer is no

Yeah, just saw they hire someone from other countries as contractor.

https://posthog.com/handbook/people/hiring-process#countries...

I applied to your support engineer role. :)

What is "Technical AE", I wonder?

Technical Account Executive - https://posthog.com/careers/technical-account-executive-emea

Please help me with ClickHouse.

lol cheeky reply aside (I lead the ClickHouse team here at PostHog). We have two of the largest self hosted ClickHouse clusters out there (and growing rapidly) each with Petabytes of data. We are working on really interesting solutions to problems that we would love to open source for the broader CH ecosystem:

- Declarative, cluster aware migrations

- Iceberg and S3 backed merge tree's on ClickHouse (as performant as local MergeTrees)

- ClickHouse on K8s, but on Metal instances w/ NVMe used for caching and compaction.

- Load shedding query scheduler and eventually query optimizer

We have a broad charter when it comes to ClickHouse. It's one of the things that enables us to build so many products that share the same underlying data and context. Our goal is to enable all developers at PostHog to continue building these products quickly as the team and user-base scales.

It's honestly an exciting time to be working at this company and on the beating heart of what drives it. Chat with me if you have any questions!

You got this, best of luck! Engineers with ClickHouse knowledge are def in short supply right now.

To job seekers, this is your sign. Learn about how ClickHouse works. If you know SQL, you're halfway there. The other half is learning ClickHouse's data storage model which is what gives it it's efficiency.

find god

I pray to Alexey every day.

Applied for the Product Engineer role. Just give me a shot at the interviews. I won't disappoint :)

Ascertain is a healthcare AI startup backed by Northwell (New York's largest health system) and Deerfield. We're a small team automating the painful admin work that clogs up the U.S. healthcare system — things like prior authorizations, discharge planning, and insurance claims. Our goal is simple: give time back to clinicians so they can focus on patient care, not paperwork.

We've found early product-market fit and are growing the team thoughtfully. We're hiring senior engineers across the stack: backend, frontend, and AI/LLM. We're NYC-based and hybrid (most of us come in ~3 days/week). We're not counting badge swipes — we just want teammates who want to be in the room with us often enough to build trust, have fun, and work on hard problems together!

What we're building:

* A general-purpose automation platform for healthcare ops, powered by LLMs

* A system that reads unstructured documents, fills out payer forms, and explains rejections

* Tools to automate patient discharge planning in hospitals

* A foundation for making AI in healthcare safe, observable, and human-in-the-loop

What we're looking for:

* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship

* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability

* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed

More importantly, we're looking for engineers who like open-ended, ambiguous challenges, and want to work with a tight-knit, high-trust team to solve real-world problems.

Pleas remember that we are looking for NYC local only, no exceptions at this time :(.

I'm a Principal Engineer here — if anything here resonates, drop me a line at john@ascertain.com or apply at our job board using https://grnh.se/f303c36d6us!

Def interested in the FE role - but heads up that your job board link seems broken!

Substrate Labs | Founding Engineer | NYC or remote | https://www.notion.so/Substrate-Labs-Founding-Engineer-2067b...

Founders Ben [0] and Rob [1] have been friends since meeting at Venmo in 2013. Ben worked at Stripe for 8 years. Rob worked at Fin (human-in-the-loop AI executive assistant, before LLMs) and was founding engineer at Substack. We started our first product, Substrate in 2023, a platform for building agentic workflows, and raised an $8M seed round led by Lightspeed [2]. We were pushing the envelope on both infra (serving multi-model workloads efficiently) and developer experience (ahead of our time in several ways) [3]. Though we found solid traction with startups, we realized inference was a red ocean especially upmarket, and decided to spin down the product/team at the end of 2024. We've spent the last 6 months prototyping and discarding ideas, and we’re now gearing up to launch our latest vision, a consumer AI application.

VIVA Finance | Atlanta, GA | Back-End Developer

VIVA is a Fintech Startup based in Atlanta, GA with the mission to build a more inclusive financial system. VIVA offers unsecured personal loans to customers who have traditionally been excluded and taken advantage of by the legacy financial institutions. The VIVA difference is to underwrite heavily on employment history and set up repayments through voluntary direct deposit payments from the borrower's paycheck. Our interest rates are less than 1/3 of the rates our customers are able to get from other financing options.

We have been profitable for the past year and with a new debt facility closing at the end of June, we will be dramatically ramping up origination volume in the second half of the year. We are hiring an additional backend engineer to support the larger transaction volume, as well as to support new products we plan to launch to diversify our revenue stream. You will join our engineering team of 10 and work in a dynamic environment where you are frequently writing net new code to support business objectives.

Our tech stack for the back-end is fully on AWS, using Lambda and ECS for compute and Typescript as the language, but experience with this specific stack is not necessary for talented candidates. Our preference is candidates who can come in office 4 days a week to our new office on the Atlanta Beltline (next to Krog Street Market). VIVA does not provide visa sponsorship, so please have authorization to work in the USA.

You say NYC here, but the job ads say NJ?

Hoboken is super easy to get to from NYC. I live in NYC and I used to work in Hoboken or about two years, it's just a couple stops on the Path train. It's not uncommon for Hoboken companies to list NYC as a result, because it's still in the same metro area.

Yeah we're opening an engineering office in NYC, TBD whether it's Manhattan or across the river, likely depends on the location of the next few hires.

Thanks! FWIW, I think that means you're required to comply with NYC's pay transparency laws and provide salary ranges. https://dol.ny.gov/pay-transparency

Make an Impact on Climate! Looking for Data Stores and Full-Stack Engineers (Remote, US)

At Insight M, we combine innovative aerospace systems with advanced data science. Unlike traditional aerospace companies, we sell information, not hardware - we operate our sensors cost-effectively at a continental scale to produce novel data streams about pressing global problems.

First on our list: spotting hard-to-monitor emissions of methane, a potent greenhouse gas that accelerates climate change. Since starting continuous survey operations in 2018, Insight M has removed methane emissions equal to over 250 million tonnes of CO2e through our work. To put that in perspective, that’s equivalent to over 60 million cars being removed from the roads or shutting down about one hundred and sixty 350 MW coal-fired power plants for a year. That's like planting 4.2 billion urban trees and letting them grow for 10 years.

We call that a good start.

As a team, we love science and engineering, we love getting our hands dirty with hardware and software, and we love seeing our work make a difference in the real world.

We’ve created a diverse, collaborative, supportive, and fun environment based on integrity and treating people right. So no matter your sex, gender, sexual identity, gender identity, race, age, beliefs, sexual orientation, or disabilities, we welcome you and would like to work with you. :-)

It’s never boring, it’s always challenging, and we’re usually laughing.

A note of encouragement: If you don't meet 100% of the qualifications on our open job descriptions: https://jobs.lever.co/InsightM, you should still seriously consider applying.

Individuals with a disability are encouraged to contact [interview.accommodations@insightm.com] to request assistance with your application and accommodations in advance of your interview.

New Lantern | https://newlantern.ai | Software engineers (infrastructure engineers & backend-leaning product engineers) | Full time in San Francisco, CA (ONSITE)

New Lantern is hiring software engineers to help build an AI copilot [1] for radiologists.

Radiologists are experts at diagnosing disease in medical images, but they spend over half their working hours on tasks that have nothing to do with diagnosis: reading prior reports, transcribing handwritten notes, taking manual measurements, dictating reports, and chasing down follow-ups. New Lantern is building an AI copilot for radiologists to automate this non-diagnostic work, so radiologists can focus on what they do best: caring for patients and interpreting images.

We are starting to find product-market fit and recently raised a $19M Series A from Benchmark [2]. Demand for our product is growing, and we're hiring software engineers in San Francisco to help us scale our product and our team. We work together in person five days a week from our office in Jackson Square.

Engineering is at the heart of New Lantern. Our engineers work directly with our founder/CEO, our staff radiologist, and our end users to build features that radiologists rely on daily. Everyone has real ownership and autonomy, moves quickly, and ships meaningful work frequently. We're a small, sharp team of frontend, full-stack, and backend engineers building a React-based web app backed by Python services, cloud infrastructure, and LLMs.

I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai.

[1] We translate "AI copilot" to "AI radiology resident" when we speak with medical professionals, but the former is the clearest way to communicate what we're building here.

Solace Health | Various Roles | Remote (US Only)

The U.S. healthcare system wasn’t built for patients. It’s massive, confusing, exhausting, and designed to wear people down. It denies access, withholds clarity, fails to take patients seriously, and rarely shows them how to fix what’s broken. When care gets delayed or denied, patients are often left with more questions than answers.

At Solace, we’re on a mission to empower patients & improve outcomes. By helping people work with professional health advocates, Solace serves as an integral, personal support layer for health issues in a way that the health system can’t. Using proprietary technology to match patients with experienced advocates, Solace cuts through the red tape of healthcare and helps individuals and families make informed decisions that result in better outcomes.

Solace is a Series B startup founded in 2022 and backed by Inspired Capital, Craft Ventures, Torch Capital, Menlo Ventures and Signalfire. We have a lean, fully-remote U.S. team distributed coast-to-coast.

Same jobs posted for the last few months. Are these real or is it really that hard to fill the roles?

I would love answers to these type of questions. I think best way to figure this out is to look at the graphs of headcount on LinkedIn and see if its growing

Adora AI | Senior Backend Engineer | Full-time | Seattle, WA | ONSITE At Adora, we're fixing performance marketing – an industry where brands get stuck with opaque algorithms that optimize for everyone except them.

Members of our team spent years at the big platforms and ad networks, and we know exactly how broken it is. Now we're building something better – a platform that finally puts brands in control with AI that works for them, not against them.

We recently raised our seed round led by Village Global (backed by Reid Hoffman, Jeff Bezos, Mark Zuckerberg). Real customers are already using our product and seeing results. Your work will directly impact how fast we can scale this thing.

What makes this interesting: • Daily work with cutting-edge AI tools, figuring out how to make them actually useful for marketers • Direct line to customers – you'll see your code impact real businesses immediately • Small team where your technical decisions matter and stick around

We're looking for someone who's shipped backend systems at scale and either loves the startup chaos or is ready to dive in. You'll own features end-to-end and have real autonomy over technical direction.

Python/MySQL/AWS/BigQuery is our current stack but we care more about your problem-solving approach.

If you want to work on hard technical problems with immediate business impact instead of yet another CRUD app, let's talk.

Camber (YC W21) | Senior Software Engineer | NYC | Onsite / Hybrid | camber.health

Camber (fka Juniper) operates at the messy financial infrastructure for US Healthcare. We've built an automated end-to-end insurance billing system for recurring care, starting with Autism clinics.

At Camber, we’ve built an end-to-end billing system. We’ve built something really good, something that clinicians really need and love. We automate and abstract the tedious, manual, repetitive work that goes into the administrative duties of running a clinic, so that clinicians can do what they do best — providing high quality care. It starts with ingesting clinic data, and then create, validates, and submits claims to insurance providers across the country. If claims need corrections or appeals, most of the time we can handle those automatically or our CX and Operations team use our in-house internal tools. We also handle patient invoicing for co-pays, co-insurance, and deductibles.

We are a team of ~40 with strong product market fit — in Q4 last year we’ve had to push out onboarding because engineering can’t build quickly enough, something we’ve scaled out of. You’ll be working with an engineering leadership team from AWS and Stripe to get clinicians back to work delivering care for kids.
