Class Central | Developer Education Specialist (Course Guide Author) | Remote (Global) | Full-time | We’re the most popular search engine for online courses, and we’re hiring a deeply technical writer-researcher to help learners master tech skills by testing advanced courses and publishing “best course” guides.

You’ll: research, test, and evaluate courses (e.g., LangChain, DevSecOps, Nginx, pen-testing) and write clear, actionable guides with charts/images/layouts.

You are: a curious polyglot learner and clear writer, fluent with the command line, and comfortable driving projects in a remote team.

How we work: full-time, remote-first, async, very few meetings; we’re profitable and independent so you can ship fast and have real impact.

AI policy: AI can speed you up, but this is hands-on research and writing—you find and test the best courses yourself (not a prompt-engineering role).

Process: application review → paid writing test → interview with founder → paid trial → decision.

Everyone says early PMF is crucial, but there is no streamlined support there.

We're hiring across disciplines for engineers who work with Unix and have fluent written and spoken English:

Stellar | Amsterdam, the Netherlands | Onsite (2 days remote OK) | €70-100k + equity | https://stellarcs.ai

Hey, I'm one of Stellar's founders. We're building voice AI for large contact centers.

Everyone thinks contact centers are boring. They're wrong. It's the last place where companies actually talk to their customers. We listen to calls every week and it's fascinating. AI here actually helps real people: shorter wait times, 24/7 support, lower cost.

Stellar skips the robotic text-to-speech pipeline entirely and works directly with voice. Our conversations are remarkably human, also in non-English languages and local dialects, where most AI sounds like a bad GPS navigator. On top of this, we're great at integrating with the complex systems at enterprises, and meeting their compliance requirements.

We're cash-flow positive, growing fast with enterprise clients queuing up, and all founders still code. We need engineers who can jump between our Go and TS backends and React frontend. This role is perfect if you:

* Want massive ownership at a small team (not pretend "impact" at BigCo)

* Actually enjoy solving hard problems (real-time audio at enterprise scale)

* Think making AI sound human in niche dialects is a fun challenge

New Hedge fund | Sr IC Frontend Engineer | Full-time | On-site (NYC)

We are a new discretionary, tech industry focused L/S hedge fund, founded by a portfolio manager with 15+ years of experience at a well known Tiger Cub. I lead the data/technology team here and previously spent ~6 years in a similar role at that firm as well. 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 are hiring for a frontend IC engineer for our internal web application.

One of our core advantages is marrying domain experts (ie. experienced fundamental investors from top tier hedge funds) with tech talent. Our frontend (the design, the UX, the UI) _really_ matters to tie the two sides together. The quality of the data we can collect, the speed of testing new ideas, and there ultimately success is driven by the quality of our frontend -- as unintuitive as that might sound.

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

- 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.

- 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.

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

If you are interested, I would love to hear from you:

- Contact: ai at nx1 dotcom , I'm Alex. - Please include resume or LinkedIn and some example of something you have built (could be Github, could be your current company, anything really)

If you want to learn more about types of things we think about, I will shamelessly direct you to my blog where I write about the space (and did so more while I wasn't at any fund): https://magis.substack.com

Tram Case | www.tramcase.com| Hiring Tech Lead and Senior Engineering Manager (Hybrid in LA or CDMX) and Remote Engineers (LATAM) - Fluency in both Spanish and English is required for all roles.

We’re building software to help high-volume law firms handle their caseload more efficiently—starting with an AI assistant that transcribes and classifies inbound calls so teams can focus on what needs action. That system is already in use, and we’re now expanding into case tracking, follow-ups, and broader workflow automation.

We're looking for a Tech Lead and Senior Engineering Manager based in Los Angeles or Mexico City (hybrid). You’ll work closely with the founders, lead a small team of senior engineers, and take ownership of key technical decisions. It’s a hands-on role with room to influence both product direction and team structure as we grow.

We’re also hiring senior backend, frontend, and AI engineers across LATAM (remote). You’ll be part of a tight, experienced team focused on building tools that solve real operational problems inside legal teams.

Our stack includes Python, JavaScript/TypeScript, Postgres, Kubernetes, and GCP.

If you're looking for thoughtful engineering work in a fast-moving environment, we’d love to hear from you.

Third time I've seen this ad. I responded to this two months ago, with twenty years experience, with the last five in ETL with Django specifically. In PST and the "one people come to with problems."

Did not even receive a reply. Certainly they've seen a worthwhile candidate by now.

This is about versafeed btw.
