🤖 The Application Security crew - within Tech Foundations area

🎯 Mission

• Tech Foundations enables product crews and creates the 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: 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…).

👀 Focus for 2026:

In 2026, we will grow the team significantly to further increase our impact. We want to complete the modernization of our authentication flows and make it operable at high availability, unlock strategic initiatives by shipping new authentication/encryption flows. We are also evolving our AI-augmented development, by putting AI code assistants as a first-class citizen for everyone, including non-engineers. Ultimately we have massive ambitions around our Security stack and posture with enhanced tools and processes to protect our developers and users.
