Senior Security Engineer (Infrastructure)

1 in 4 people in the US have a treatable mental health condition, but most providers don't accept insurance, making therapy too expensive for most people. Headway’s mission is to fix this by building a new mental healthcare system everyone can access. We started by solving the biggest barrier to care: insurance. The admin work - credentialing, claims, payment reconciliation - is a nightmare. We've automated that.

But we're going further. Over 90,000 providers across all 50 states run their practice on our software, serving over 2.6 million patients. We are building the best tools for therapists to run their entire practice, reimagining the experience of finding a therapist, and investing in the platform foundations to enable this at scale, and building much of it with AI. We aren't just a billing layer; we are becoming the platform where care actually happens.

We're a Series D company with $325M+ in funding (a16z, Accel, Spark Capital, etc.), looking for exceptional people to help us achieve this mission. We want your time here to be the most meaningful experience of your career. Join us, and help change mental healthcare for the better.

  • Doing security reviews

  • Helping with system design decisions

  • Continuous improvement of Headway's critical infrastructure

• Make the safe way, the easy way: Work on defining and building infrastructure and application guardrails so that developers can build securely by default. You also will work to instill a culture of secure system design across engineering.

You’ll be great for this role if you have:

• Strong cross-functional experience: You love partnering with other teams to help both teams achieve their goals.

• Strong technical depth and breadth: You have technical experience with building secure platforms and products at a deep level. You are excited to perform security design and code reviews. You want to understand security systems and improve their efficiency and scalability.
