- Develop dashboards, user flows, permissions, and workflow systems
- Integrate AI models such as OpenAI, Claude, Gemini, or similar
- Use AI development tools such as Codex, Claude Code, Cursor, or comparable systems where useful

- Experience with React / Next.js
- Experience with Node.js and/or Python
- Experience with PostgreSQL, Supabase, Firebase, or similar databases
- Understanding of APIs, authentication, roles, permissions, and workflows
- Familiarity with prompt engineering, agents, RAG, embeddings, or automation
- Ability to think through product decisions, not just execute tasks
- Clear communication and strong technical judgment
- Availability to work on-site in Paris
Nice to Have
- Experience deploying on Vercel, AWS, or similar platforms
- Experience with workflow automation tools
- Experience with AI agents or multi-step AI systems
- Experience working in early-stage product environments
- Experience using AI coding tools such as Codex, Claude Code, Cursor, Replit Agent, or similar
Ideal Candidate
You are a strong fit if you can code, think strategically about product, integrate AI into practical workflows, and help turn a platform idea into a working MVP. We are looking for someone technical, independent, product-minded, and comfortable working closely with a small founding team in Paris.
