Senior Site Reliability Engineer, Tenant Services: Geo

Environment preparation and data hygiene checks prior to migrations. - Execution of replication, validation, and cutover procedures. - Handling Geo-related escalations from Support and internal partners. - Design, build, and maintain automation, tooling, and runbooks that make migrations, cutovers, and Geo escalations as “boring” and repeatable as possible. - Run our infrastructure with tools such as Ansible, Chef, Terraform, GitLab CI/CD, and Kubernetes; contribute improvements back to GitLab’s product and infrastructure where appropriate. - Build and maintain monitoring, alerting, and dashboards that:

Detect symptoms early, not just outages. - Track migration and cutover success rates, duration, rollback frequency, and related SLOs. - Collaborate closely with:

The core Geo team on improving Geo features and operability. - Dedicated migrations and Support on migration planning, customer communications, and escalation handling. - Other Infrastructure teams on capacity planning, disaster recovery, and reliability improvements. - Contribute to readiness reviews, incident reviews, and root cause analyses, turning learnings into changes in automation, process, or product. - Document every action, including runbooks, architecture decisions, and post-incident reviews, so your findings turn into repeatable practices and automation. - Proactively identify and reduce toil by automating repetitive operational work and simplifying migration workflows. ## What you’ll bring

Experience operating highly-available distributed systems at scale, ideally in a SaaS environment with customer-facing SLAs. - Hands-on experience with at least one major cloud provider (e.g., Google Cloud Platform or Amazon Web Services), including networking, storage, and managed services. - Experience with Kubernetes and its ecosystem (e.g., Helm), including deploying and troubleshooting workloads. - Experience with infrastructure as code and configuration management tools such as Terraform, Ansible, or Chef. - Strong programming skills in at least one general-purpose language (preferably Go or Ruby) and proficiency with scripting (e.g., Shell, Python). - Experience with observability systems (e.g., Prometheus, Grafana, logging stacks) and using metrics and logs to troubleshoot performance and reliability issues. - Practical exposure to data replication, backup/restore, or migration scenarios (e.g., database replication, storage replication, or Geo-like technologies) where data integrity and downtime risk must be carefully managed. - Comfort participating in an on-call rotation, investigating incidents across the stack, and driving follow-through on corrective actions. - Ability to engage directly with enterprise customers during migrations and incidents, including on live calls and through clear written updates. - Ability to clearly define problems, propose options, and think beyond immediate fixes to improve systems and processes over time. - Ability to be a “manager of one”: self-directed, organized, and able to drive work to completion in a remote, asynchronous environment. - Strong written and verbal communication skills, with a bias toward clear, asynchronous documentation and collaboration. - Alignment with our company values and a commitment to working in accordance with those values.
