ProPublica | Director of Product Engineering | Remote (US only) or NYC | Full-time

ProPublica is a non-profit newsroom that investigates abuses of trust in the public interest. Journalism we published last year shed light on the impact of DOGE and ICE, investigated right-wing militias, told stories about the US medical system, and more. Here were our most-read stories in 2025: https://www.propublica.org/article/propublica-most-read-stor...

I'm the Senior Director of Technology. I'm hiring a pragmatic, mission-driven Director of Product Engineering, who will report to me, in order to provide more support for our product engineers who work on our publishing and data products. (This is not a reporting position.) You'll directly lead and manage a small team of engineers and help us to create and maintain great engineering processes.

More about the role here, including a direct route to apply:

https://job-boards.greenhouse.io/propublica/jobs/4623874006?...

Or get in touch with me at ben.werdmuller [at] propublica.org if you'd like to have a conversation about it.

The expected salary range for this position is $170,000 to $180,000. We cannot sponsor visas and must hire in the US. The role is almost fully remote: we have two in-person week-long summits a year.

Stealth | Software/AI Engineer | Remote Anywhere | Full Time

Hello, I am bootstrapping an AI companion startup. I believe that within 10 years, more people will date AI than humans. I think this is neither good nor bad, just interesting, and I want to build something in this space.

I am looking to hire someone with strong technical and problem solving skills. You will be seeing a lot of problems for the first time and need to just figure out how to hack a solution. Sometimes that involves writing code but not always. It is ok if you don't have prior AI experience.

Interesting problems we will work on:

- extreme latency issues while providing a fully multimodal experience (audio, video, text)

- building models that predict when to interrupt in a conversation

- building models and control systems for emotion

- generating avatar response in real time

- custom 3d models from input image

- real time or very fast video generation with custom characters

- llm memory

As I am bootstrapping this, I can only offer up to $4,000/mo ($50,000/yr) at the moment. If you are interested, please email James at gcyiuqy1 [at] gmail.com

Positron | Bootstrapping Startup | South Korea | Co-founder

Equity-only co-founders. If you must take a salary position, send us a resume with "Salary only" and we'll check back later.

We're developing an efficient social-decision model so that communities can organize social-finance campaigns and effectively administrate funds without being beholden to one creator. Keeping funds in the hands of backers creates accountability and is one key to taking social finance to the next level.

We say that our social tech "makes the money smarter." It will do this by making communities smarter. How we do social will change how every future social platform gets built and will upset every social product on the market. Society will benefit tremendously from the more coherent discourse.

To bootstrap our platform, we are developing an music visualizer called MuTate. It will soon be powered by our in-house machine learning tricks, which do not rely on back-propagation in order to enable radical forward architectures that are smaller and easier to develop and train. This work directly impacts our mission and aligns us both with consumer enthusiasm for small & local AI to run outside the cloud and with people working on hard problems that need AI tool-kits they can embed their own world models within.

We are using PrizeForge as a better kind of Patreon while we finish our crowd cognition implementation and start to integrate social decisions with our existing social finance.

Our entire tech stack is Rust where possible. We use Leptos, Axum, Postgres with SQLx. It's like a full-stack typescript setup, but with Rust and WASM. MuTate uses Rust, the Vulkan API, and Slang.

Anyone who materially accelerates the trajectory of the company will participate proportionately in the rewards. Our work on MuTate will put us default-viable. Our work on crowd cognition and community-organized campaigns will likewise make use default-viable.

Prototype two-dimensional fund raising: https://prizeforge.com Career listings with more details: https://positron.solutions/careers MuTate Github repo: github.com/positron-solutions/mutate

Korean language skill is optional but anticipate learning business Korean and translating a lot. Same timezone is as far as will be considered remote unless you're physically stuck in Ukraine etc and begin by contributing on MuTate.

I applied to the Frontend Engineer Role last month, but haven't heard back yet. Would it be possible to bump up the application?

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
