Senior Software Engineer, Identity

Build and scale the backend systems powering Stytch’s identity platform within Twilio, delivering secure, developer-first authentication and authorization experiences. You’ll design and ship RESTful API surfaces and core identity flows (including agentic and non-human use cases), partner with product/engineering to drive high-impact roadmaps, and evolve platform capabilities for Twilio’s scale. Own technical decisions end-to-end, improve observability and resilience, and mentor engineers in a high-ownership environment.
