Summary from the posting
As a Senior Full Stack Engineer on the Platform Team, you will develop and operate Alpaca’s authentication, authorization, and Identity Provider (IdP) systems - the systems that handle user login, access control, and secure access across our APIs, customer products, and internal tools.
We are looking for experienced engineers who are comfortable owning services end to end: API design, data modeling, deployments, and production debugging. Most of your time will be spent writing Go (backend services, gRPC/REST APIs, shared client libraries), with meaningful work in React/TypeScript for auth-related UI, and occasionally Java for identity-provider extensions.
This is a short summary. The full description, requirements and the application form are on Alpaca's own career page.
