Requirements
- We need engineers who build systems, not features, people who own outcomes end-to-end, orchestrate AI to execute, and raise the bar for everyone around them.
- You'll write specs that agents execute, review AI-generated code with a critical eye, and make decisions that compound over time.
- We'll shape the exact scope together, mobile, infra, platform, AI, full-stack, based on where you're strongest and where we need it most.
- What you could own: - Full-stack vertical ownership: from data model to API to UI, you hold the whole slice and make it production-grade - Algorithms: translate clinical science (in collaboration with our medical advisors) into reproducible, auditable code - System architecture: design scalable, HDS-compliant infrastructure on AWS (CDK/Terraform) that can handle 10× the load without rework.
- You use AI the way others use a calculator: naturally, to go faster and think bigger.
- You’ll fit in well if - You've shipped at least one product from 0→1 and felt the difference between writing code and building a system - You have 2 deep areas of expertise and can operate across the full stack when the situation demands it - You write specs before you write code — precise enough that an AI agent executes correctly on the first pass - You review AI-generated code with the same rigor you'd apply to a junior engineer's PR: edge cases, security gaps, design smell - You bias toward shipping.
- A good decision today beats a perfect one next week - You're genuinely interested in health — maybe you track your own biomarkers, or you're just frustrated that healthcare is still reactive We would not be a fit if - You need a clearly scoped role before you can operate - You measure output in lines of code written - You've only worked in large orgs with dedicated infra, QA, and platform teams - You optimize for stability over velocity Our current stack TypeScript monorepo Next.js NestJS PostgreSQL +
- AWS (Terraform, Qovery) GitHub Actions
- At Lucis, AI isn't just our product, it's our engine. 100% of our teams are equipped with the best AI agents.
- You have carte blanche to explore and automate everything that can be, so you can focus exclusively on high-value work.

- Claude Code + Cursor THE PROCESS - Intro call (20 min): culture & role fit. - Technical interview (30 min) - At-home case study: hands-on project, delivery in 2 days. - Deep dive (90 min) and team chat (on-site) - Reference calls HOW WE WORK We work together from our Paris hub.
- We’re passionate about what we’re building and believe the fastest way to create something exceptional is side by side.
- We’re open to relocation support for the right individuals, and we welcome missionaries who travel to work with us in Paris on a regular basis. - Rigor without ego: Audits, science, and code all deserve the same high bar. - Radical ownership: Feedback loops are short; everyone contributes to building the best version of Lucis. - Velocity over perfection: We ship daily and prefer a good decision today over a perfect one next week.
