Making preventive health the default for every human in Europe
The mission
At Lucis https://lucis.life/?utm_source=career_job_desc&utm_medium=content, we believe healthcare should be preventive, not reactive. We’re building the OS for human longevity to help people add more healthy years to their lives. You can read more about who we are and how we work here https://lucis.life/careers?utm_source=career_job_desc&utm_medium=content.
We've processed 200,000+ clinical tests across 4 countries with a team of 20. We're growing 10% week over week. And we're still early.
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 won't spend your days writing boilerplate. You'll write specs that agents execute, review AI-generated code with a critical eye, and make decisions that compound over time. This is what engineering looks like now. If that excites you, keep reading.
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.
We're scaling across the EU, with the complexity that comes with it: new countries, currencies, payment methods, and regulations. This is code where a subtle bug costs real money and real trust. You care that the model is right before the endpoint exists, and that every edge case fails safely.
You'll own what a first-time visitor meets and what keeps members coming back: the acquisition funnel, onboarding, checkout, the everyday surfaces of the product. Your work has to be delightful and reliable for people who have never heard of us and decide in minutes whether to trust us with their health.
You’re passionate about the future of human health and want your work to help people stay healthy for longer. You move quickly from idea to execution, take full ownership of what you build, and work best with talented people who care as much as you do.
You thrive in fast‑moving environments, learn by doing, and value feedback as a way to continuously improve. You use AI the way others use a calculator: naturally, to go faster and think bigger.

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.
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.
