Senior Software Engineer, IAM

Senior Software Engineer, IAM Docker has been one of the most loved brands in developer tooling, trusted by more than 20 million monthly users and over 20 billion container image pulls. From solo founders to the world's largest companies, developers rely on Docker to build, share, and run their applications across our suite of products including Docker Desktop, Docker Hub, and Docker Scout. We are a globally distributed, remote-first team building the tools that define how software gets built and delivered. As AI agents redefine software development, Docker is at the center of that shift, providing the sandboxed environments, verified images, and secure infrastructure that make autonomous workflows trustworthy by default. We're looking for a Senior Software Engineer to join our IAM team. The IAM team owns Docker’s identity backbone: the systems that determine who a user is, what they can do, and how organizations govern access at scale. Every authenticated request to Docker depends on these services—making their correctness, latency, and security foundational to customer trust. The team owns authentication and authorization, access tokens, OIDC, SSO, and SCIM, and user and account management systems, along with supporting enterprise services. You'll work on systems used by millions of developers and the world's largest organizations, with the governance controls enterprise customers require. This is a high-impact role for an engineer who enjoys deep backend work in a space where correctness, latency, and security all matter - and where the design decisions you make today shape how Docker scales identity for years to come. RESPONSIBILITIES - Design, build, and operate Go services powering authentication, authorization, token handling, and identity lifecycle across Docker - Extend OIDC, SSO, SAML, and SCIM integrations, and evolve our authorization model (including ReBAC) as permissions scale across products and tenants - Improve observability, performance, and security posture of identity services on the hot path of every authenticated request, and strengthen audit logging - Design for multi-region operation, graceful degradation, and safe rollout of changes to critical auth flows - Lead projects end-to-end, contribute to technical design and long-term direction of the IAM platform, and mentor teammates in identity and security domains - Partner with Product, Security, and engineering teams that depend on IAM primitives to ensure our APIs are clear, safe, and easy to adopt - Take part in the paid on-call rotation for the team; respond to incidents, debug production issues, and drive continuous improvement of system reliability WHAT YOU'LL WORK ON Beyond steady-state ownership of our identity services, you’ll help shape the next phase of Docker’s IAM platform, including evolving our authorization model for fine-grained, cross-product access, expanding support for enterprise identity integrations, and improving the reliability and observability of systems on the critical request path. QUALIFICATIONS - 6+ years of backend software engineering experience building and operating production services - Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience - Strong proficiency in Go, including building and operating services in production - Solid working knowledge of PostgreSQL - schema design, query performance, migrations, and operating Postgres under real load - Experience with gRPC and event-driven systems using Kafka (or comparable) - Experience operating on AWS - Strong understanding of core identity and security concepts: OAuth2, OIDC, SAML, JWT, token lifecycle, and session management - Experience with authorization models, including RBAC and ReBAC-style approaches - Track record of designing and operating distributed systems where reliability, security, and correctness are first-class concerns - Willingness and ability to participate in an on-call ro ...
