Software Engineer | Identity & Access Management | Full-Stack

About the role

DeepL is building a global AI product focused on secure, intelligent solutions for complex business problems, and the Identity and Access Management team is central to that mission. In this role, you will own the implementation of end-to-end features across our full identity stack, including organisation, group, account, consent, and session management, SSO federation, SCIM provisioning, and the OIDC provider for both internal and external users. You will not simply write isolated functions; you will ensure every feature you ship solves a real user problem, works reliably in production, and is supported by robust tests and monitoring. You will collaborate closely with teammates across Identity and adjacent teams, participating in code reviews and design discussions to raise the bar for quality and reliability. This is a mission-focused role for builders who obsess over the Why before the How and want to shape the future of AI-driven communication. If you are ready to grow your career in a fast-moving, purpose-driven environment, DeepL is your next destination.
