Fullstack Software Engineer

Health can't wait. Not for symptoms to get worse. Not for a six?month appointment. Not for a system to catch up. But that's exactly how healthcare works today. You wait, until you can't.
Alan exists to end the wait.
Health is a universal right, and we believe this right can only become real when it's coupled with prevention. We need to stop treating health as something we repair and start treating it as something we build, every day. It's not solely a question of willpower. It's the healthcare system itself that needs to work for everyone, in a sustainable way.
So we are building the new standard in prevention insurance. Alan is the first company that integrates insurance, prevention, and care into a single, acclaimed user experience.
We are on an incredible journey to build a global leading company, with a unique culture. We already partner with 40K+ companies of all sizes, serving more than 1M+ members, and have reached €800M+ in ARR.
Prevention as the new norm. That's what we're building with our team of ****+ people. If it speaks to you: we're hiring across France, Spain, Belgium, and Canada. And beyond.
Who we are
You. Better. With Alan.
Alan's vision is to make prevention the new norm of care for all. Our mission is to help people live in good health to 100 while helping employers feel proud, turning health benefits from a cost center into their most valuable investment.
What You'll Build And Who You'll Work With
You would join the product team that builds the AI agents answering our 1M+ members' questions about their health insurance - reimbursements, coverage, claims, account changes and more - instantly and without waiting for a human.
Concretely, You Will
Design and ship LLM-powered agents that understand a member's request, reason over their contract, claims and history, and take real actions on their behalf - building the tools, retrieval and context pipelines that give them the right information at the right moment
Make our agents interoperate with other AI agents across Alan, such as Mo: handing off conversations, sharing context and calling each other's capabilities, so members get one seamless experience
Bring automated resolution to new channels, starting with AI phone support: real-time voice conversations with the same quality bar as written ones
Own evaluation: build datasets, automated evals and quality monitoring so we know an agent is right before members see it
Measure and improve resolution rate, answer quality and member satisfaction in production, iterating fast on prompts, models and architecture
Work hand in hand with care experts and product to identify the next topics the AI can fully resolve
Why this role is special
Direct Impact:
Every point of automated resolution means members get help instantly, when they need it the most - and directly drives Alan's scaling, growth and profitability.
Applied AI at scale:
You won't build demos. You'll ship AI agents that handle hundreds of thousands of real conversations per month in a regulated, high-stakes domain, where accuracy truly matters.
Frontier problems:
Agentic workflows, tool use, evaluation, safety and guardrails, cost and latency trade-offs - you'll tackle the hardest open questions in production LLM systems.
Ownership & Growth:
Influence product direction, mentor other engineers, and lead technical initiatives that shape the future of healthcare access.
What we're looking for
Technical Requirements
5+ years building scalable software systems
Strong backend experience (Python is a plus)
Hands-on experience building products with LLMs (agents, tool calling, RAG, prompt engineering, evaluation) - ideally shipped to production
An evaluation mindset: you know how to measure whether an AI system is actually good, and how to make it better
What we value
You love turning complex problems into elegant solutions
You care about the \"why\" behind what you build, not just the \"how\"
You stay on top of a fast-moving AI landscape and are pragmatic about what really works
Humble and still willing to grow (no matter your seniority)
Mission Alignment
Healthcare technology excites you
You understand that insurance isn't just about money - it's about access to care
But above all, we are looking for high potential and curiosity: make sure to show us this when you apply Everything else is a bonus.
