What you'll work on
Our roadmap moves fast; what you'll ship in September isn't on the board today. But a taste of what's live right now:
- AI agents: assistants that reason about inventory decisions and apply optimizations
- Query optimization: PostgreSQL at a scale where EXPLAIN ANALYZE is a daily read
- Real-time data at scale: SSE, Redis pub/sub, synchronisation of Kubernetes pods
- Frontend craft: virtualised data tables, faceted filters, charts
Tech stack
FastAPI • Vite • Python • TypeScript • PostgreSQL • SQLAlchemy • Kubernetes
Who we're looking for
Serious, strong, passionate engineers.
If you've shipped a side project, contributed to open source, spent a weekend hunting down a weird bug, optimised something nobody asked you to optimise, or obsessed over the details of a UI until it felt right, we want to talk to you.
You'll fit in here if you:
- Have solid software engineering fundamentals
- Move fast and figure things out on your own
- Care about the craft, not just the ticket
What you get
- Real ownership: you'll ship to production in your first week
- A YC-backed startup at the stage where your work actually has impact
- Daily mentorship from engineers who've shipped at scale
- The full stack: backend, frontend, database, infra. Find out what you love.
- A path to full-time if it clicks on both sides
Logistics
- On-site, Paris
- 6 months, starting September 2026
- €1000–1500 / month depending on level
- English. French is a strong plus
