An overview of this role

As a Senior Site Reliability Engineer (SRE) at GitLab, you'll help keep all user-facing services and production systems reliable, scalable, and efficient. Our SREs combine a pragmatic operations mindset with strong software engineering practices to drive automation, reduce toil, and improve resilience across our platform.

Within the US Public Sector Services team, you will specialize in operating a large fleet of GitLab environments built to meet FedRAMP compliance requirements. Your role centers on three core responsibilities: automating workflows across the full environment lifecycle—from provisioning new environments to daily operational tasks—deploying features and updates safely and consistently, and maintaining operational excellence across many production environments simultaneously.

This specialization uniquely integrates the demands of operating at scale with the rigor of public sector compliance—balancing strategic automation development and hands-on operational execution while upholding the strict security and regulatory standards required for government customers. Candidates must be U.S. citizens residing and working in the United States, and be willing and able to obtain U.S. federal security clearance (minimum Public Trust position).

Some examples of the projects you could work on:

• Designing and coding infrastructure automation that provisions and operates GitLab environments using Terraform, Ansible, and Kubernetes
• Creating and maintaining deployment packages for GitLab, such as Helm Charts and omnibus-gitlab
• Building and operating Dedicated GitLab instances integrated with cloud-native services (e.g. AWS, GCP)
• Developing tools to orchestrate infrastructure-as-code workflows across multiple tenants
• Deploying and managing microservices on Kubernetes clusters at scale
• Enhancing GitLab’s observability stack (e.g., Prometheus, ELK) to support proactive monitoring and incident response
• Integrating with and operating infrastructure in cloud provider ecosystems (e.g., IAM, networking, storage)
• Championing and implementing cloud security best practices across automated infrastructure
• Engage with US Public Sector entities to ensure successful implementation of GitLab services to meet Federal and regulatory requirements.

What You'll Do

• Build & Scale Multi-Tenant Infrastructure: Design and implement automation that provisions and manages hundreds of isolated GitLab environments using Terraform, Ansible, and Kubernetes. Manage complex state strategies and workspace configurations to support scale and maintainability.
• Debug & Resolve Production Issues: Troubleshoot issues across Kubernetes clusters, cloud services, and GitLab apps—identifying root causes of failed deployments, crash loops, and scheduling conflicts to ensure service continuity.
• Automate Operations at Scale: Replace manual workflows with infrastructure-as-code solutions, including automated version upgrades, configuration rollouts, and provisioning pipelines that operate reliably across all tenants.
