Synapsr is a SaaS makers lab based in Brest, France.
We build disruptive tools we wished existed — fast, clean, open source by default.
Pelli, LumyRadio, Louez, Hovod, Hushletter… 9+ projects shipped, 91% public on GitHub.
We're not looking for a contractor or an employee. We're looking for a co-founder to own our developer relations — and join the board with no financial investment required.
Tasks
- Write and maintain documentation for our open source projects
- Create technical content (articles, tutorials, threads, videos) around our stacks and products
- Grow our dev presence: GitHub, social media, OSS communities
- Handle external contributions — issues, PRs, feedback
- Represent Synapsr in the tech ecosystem (meetups, events, worldwide)
- Contribute to and improve our projects (TS, React/Next, Tailwind...)
Requirements
- Comfortable with code — you can read, test and document TypeScript projects
- You write clearly, without unnecessary jargon, with a genuine voice
- You understand what keeps an open source community alive over time
- You share our convictions and vision
Benefits
- Board entry with no financial investment — based on the value you bring
- Founding role in Synapsr's community growth strategy
- Direct access to the whole team (5 people, no middleman)
- Fully remote or based in Brest — your call
- Real-impact projects, disruptive and built with modern stacks
We're not hiring. We're partnering.
If you're looking for a stable job with a well-defined role, this isn't for you. If you want to build something, take risks, and co-found with a seasoned team in the SaaS and Open Source world — then we have a conversation to have.
No cover letter. Show us something you built or wrote — a repo, a README, an article, a video…
