Fullstack Software Engineer (Security) - Tech Foundations

Overview

Alan is building a vertically integrated health partner that unites insurance and smart healthcare delivery into one seamless system. Our vision is to make prevention the new norm of care for all. Our mission: Help people live in good health to 100 while helping employers feel proud, turning health benefits from a cost centre into their most valuable investment. By connecting all aspects of care (private, public, and direct to consumer), we create the most member‑centric healthcare experience, reducing claims costs while generating new monetization opportunities.

Leadership Principles

• Mission is the Boss – We think long‑term and are methodical optimists who take risks, seeking our mission’s success above all else.
• Distributed Ownership – Accountable enlightened despots: everyone owns their decisions and results.
• Radical Transparency – All information is accessible and written‑first, so everyone can make the best decisions asynchronously.
• Always Growing – Direct, positive, and caring feedback, combined with self‑growth ownership.

The Engineering Team

In our engineering team we build the infrastructure, interfaces, and applications to provide first‑class service to our members, health professionals, and ourselves. We move fast, take ownership, and tackle big problems. Security is a core part of everything we do.

Application Security Crew – Tech Foundations

• Tech Foundations enables product crews and creates an environment to thrive—combining world‑class infrastructure, intuitive developer experience, exquisite operational excellence, and built‑in security to make shipping exceptional products effortless.
• Application Security is one of its crews. Its mission is build, evolve and operate the foundational security building blocks and secure‑by‑default patterns that make Alan’s products safe by design , highly available , and easy to ship , while partnering with product teams and Security Operations to reduce real risk without turning security into a bottleneck.

Scope

• Security core components in the product
  • Authentication – design, build and operate the authentication stack on top of our self‑hosted identity provider. Our goal is to go passwordless with great UX and unblock strategic initiatives relying on this stack.
  • Encryption – build, evolve and operate our end‑to‑end encryption component used by our Alan Clinic while keeping it delightful and frictionless for our members.
• Security platforms
  • Secure file exchange – evolve and operate our secure file exchange platform to unblock product/ops teams while bringing support when relevant.
  • Secure enclave for medical secrecy – contribute to the foundations to isolate and protect highly sensitive medical data without sacrificing usability or delivery speed.
• Contribute to reinforce our security engineering practices (fixing security vulnerabilities, CI/CD, SAST/DAST, Infrastructure Security, AI/LLM Security, etc.).

Experience We Value

• 3+ years in full‑stack software engineering roles
• Experience designing and building products, platforms, frameworks or libraries
• You love turning complex problems into elegant secure solutions
• You care about creating secure‑by‑design products while keeping delightful experiences

Mindset We Value

• You treat security engineering as product work : engineers & members are your customers, and security should feel effortless.
• You’re an enabler : collaborative, humble, and motivated by helping teams ship safely.
• You’re hands‑on : you write maintainable code, ship to production, and care about reliability, rollouts, and real‑world operability.
• You build reusable patterns —guardrails, libraries, and secure‑by‑default abstractions that prevent vulnerabilities at scale.
• You’re fluent in English (French is a bonus).

Location & Remote Work

• Location: You must be legally eligible to work in France, Belgium, or Spain.
• Remote work: We offer remote work flexibility, but we value in‑person collaboration.
