Senior Engineering Manager (API & Auth Platform)

Join Betterment, a leading digital investment platform, as a Senior Engineering Manager for the API & Auth Platform team. In this role, you will lead a team of senior/staff engineers, drive the technical direction of our GraphQL API frameworks, and collaborate with various departments to ensure our internal APIs meet regulatory standards. You will also have a significant influence on how Betterment's APIs support AI agents and tooling in a regulated financial services environment.

• Lead and grow a team of senior/staff engineers building the API, authentication, and internal tooling platform that every Betterment team relies on.
• Drive technical strategy for the GraphQL API frameworks powering customer-facing and internal apps, including agentic tooling for AI-native API development workflows.
• Partner with IT and security on platform governance so engineering teams can build on the API platform and ops teams can operate through it with confidence.

• Experience managing shared API platforms — ideally GraphQL. An appreciation for the frameworks, conventions, and developer tooling that let product teams introduce new capabilities, support existing usage, and gracefully retire legacy functionality
• Experience partnering with IT, security, and business leaders on governance, access, and permission models. Ability to build trust across disciplines and adapt as AI tools introduce new identity and access patterns
• Experience managing senior and staff ICs; ability to coach engineers through technically complex challenges while maintaining team momentum. Capable of meaningful architectural direction, code review, and hands-on work in our codebase
• Hands-on experience with modern authentication/authorization patterns (OAuth 2.0, OIDC, passkeys), with an understanding of the importance of adoption, long-term support, and security testing
• Principled approach to balancing the need to move quickly today with the need to move quickly tomorrow, with an appreciation of how to meet high standards for customer quality and regulatory requirements
• Proven track record leading a team that owns a shared platform used by engineering, operations, and customer support teams. Experience leading projects that affect multiple teams' software systems, tooling, and development workflows
