You will join the Identity and Access Management team. Owning DeepL's full identity stack: organisation, account and session management, SSO federation, SCIM provisioning, and the OIDC provider, for both internal and external users. It is the foundation every DeepL product relies on to authenticate and authorise users securely and at scale. When identity is unavailable, no one can log in, so reliability and performance sit at the heart of everything the team does. We are shifting gears from "Software-First" to "Product-First." We don't hire engineers to simply maintain legacy endpoints or close Jira tickets. We hire Missionaries — builders who obsess over the Why before the How. You will contribute across the stack, shipping features that create delightful, frictionless experiences for both external developers and internal engineering teams. Your responsibilities Own the Identity Experience End-to-End: You will architect and build complex, user-facing features across our identity stack. You will own business-critical systems from the initial problem definition through to architectural design, deployment, and production reliability. You measure success by user impact, not just pull requests merged Build for "Consumer-Grade" Enterprise: You understand that authentication and authorization systems cannot fail. You build for reliability and maintainability, while delivering a user-friendly experience. You will lead incident response, and continuously raise the bar on code quality and operational health Collaborate to Raise the Bar: You will work closely with teammates across Identity and adjacent teams - other product teams, Product Management and Support. You will lead designs, scoping, shaping, and solving hard product and technical challenges in collaboration with your team and other engineers Drive Technical Pragmatism: Whether using our core stack (C#/.NET Core, Kubernetes, Postgres) or exploring
