• Own core platform services: Design, build, and maintain SSO and auth services, profile services, and data aggregation layers that serve as the backbone for all products • Build across the stack: Write backend APIs and services, then build the frontend interfaces that consume them • Drive architectural decisions: Evaluate trade-offs, document decisions, and guide the evolution of our service architecture • Build for scale and reliability: Design systems that handle growth gracefully with appropriate observability, error handling, and recovery patterns • Build for a multi-region footprint: Make sound decisions about data residency and data movement across the US, Canada, the UK, and Australia • Ship production code: This isn't a whiteboard-only role. You'll write code daily and own features end to end • Collaborate across teams: Work with product engineers who consume your services to understand their needs and provide clean, well-documented APIs
