An Overview Of This Role

As an Engineering Manager for the Auth Infrastructure team at GitLab, you'll lead a talented group of engineers building the critical infrastructure layer that powers GitLab's authentication and authorization systems at scale. This role focuses on the foundational components that enable secure, performant, and reliable identity services across all GitLab deployment models while supporting our transition to a zero-trust architecture.

At GitLab, we see our team as our product. While you'll need deep technical expertise in distributed systems, proxy technologies, and infrastructure security, your primary focus will be on nurturing your team's health, hiring exceptional talent, and positioning them for success.

You'll collaborate closely with the Authentication and Authorization teams to ensure the infrastructure layer can support their requirements, while working with Platform and Infrastructure teams to ensure seamless integration across GitLab's architecture.

Your leadership will be instrumental in building the infrastructure foundation for GitLab's Identity and Access Management (IAM) Services.

This is a unique opportunity to solve authentication infrastructure challenges at global scale while enabling GitLab's evolution toward microservices and zero-trust security.

This role is an extension of the Engineering Manager position.

What You'll Do

• Lead the design and implementation of GitLab's authentication infrastructure layer, including Envoy proxy configuration, token services, and policy decision infrastructure
• Solve critical infrastructure challenges including bi-directional gRPC tunnels, mTLS implementation, short-lived certificate management and service mesh architecture
• Ensure infrastructure supports multiple deployment models: GitLab.com (millions of users), self-managed, Dedicated, and air-gapped environments
• Lead performance optimization efforts for authentication decisions at scale
• Implement infrastructure monitoring, observability, and debugging capabilities for distributed authentication systems

What You'll Bring

• Significant experience in engineering management with focus on infrastructure and distributed systems
• Deep expertise in proxy technologies (Envoy, Traefik, HAProxy, nginx) and edge routing
• Experience with DB technologies and storage, such as RDS, Google Spanner, Postgres or similar.
• Strong background in Go and/or Rust for building high-performance infrastructure services
• Experience with service mesh architectures, mTLS, and zero-trust networking
• Expertise in gRPC, REST APIs, and service-to-service communication patterns
• Understanding of token systems (JWT, Macaroons), cryptographic signing, and key management
• Knowledge of Kubernetes, container orchestration, and cloud-native deployment patterns
• Proven track record of building and scaling engineering teams focused on infrastructure
• Experience with infrastructure automation, CI/CD, and GitOps practices
• Strong debugging and performance optimization skills for distributed systems
