Senior Software Engineer (Trust Foundations)

About this role: Building for trust is non‑negotiable in our mission of making mental healthcare more accessible and affordable across the US: patients share sensitive information, payers demand demonstrably strong controls, and providers depend on reliable, secure infrastructure. 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. What will make you successful in this role: 5+ years of professional software engineering with a strong command of at least one modern language (we use Python3 and TypeScript). Proven systems‑architecture leadership - you have shaped requirements, led cross‑team roadmaps, and delivered complex backend or platform services at scale. Deep expertise in one of two focus areas: Identity and Access - demonstrated experience working with third party IdPs, expertise with OAuth2.0/OIDC standards, have implemented step‑upMFA and common RBAC frameworks. PlatformEngineering (scalable, secure foundations) - demonstrated experience building high‑throughput, fault‑tolerant services that bake in security‑by‑default patterns, provide clear developer interfaces, and enable downstream teams to move faster. A track record of mentoring engineers , elevating design quality, and improving engineering processes. Sound build‑vs‑buy judgment and the ability to collaborate with product, legal, and operations in a highly regulated environment.
