Trust Foundations is responsible for instilling confidence in our products by safeguarding our user’s data. We achieve this by developing out‑of‑the‑box identity, access, and secure‑data platforms for other engineering teams to utilize. Our mission is to make the most secure path the most efficient path, enabling clinicians, patients, and payers to trust Headway implicitly. What you’ll do here: Design, build, and operate core trust primitives - authentication providers, authorization engines, stratified encrypted data stores, and tamper‑evident telemetry. Embed security & privacy by design – Codify guardrails in linting rules and CI, and partner with Legal/Compliance to translate regulatory language into concrete engineering controls. Scale our identity rails – Design and evolve multi‑tenant authentication & authorization services that handle millions of sessions daily with high availability expectations. Deliver scalable, secure platform foundations – Build shared services that embed security‑by‑default (least‑privilege access, encryption in transit and at rest, audit hooks) and expose intuitive APIs so product teams can move quickly without compromising trust. Turn ambiguous requirements into incremental delivery plans – Lead architecture reviews; break large problems into testable milestones; and make pragmatic build‑vs‑buy decisions in a regulated domain. Champion operational excellence – Instrument services, tune alerting, own on‑call runbooks, and drive post‑incident hardening. Elevate engineering culture – Mentor teammates, document patterns, and help recruit the next generation of Headway engineers.
