Senior Site Reliability Engineer, Database Excellence at GitLab

Automate operational tasks across all environments, from package updates and configuration changes to provisioning of user-facing services, so manual effort becomes the exception, not the rule.
Design and maintain PostgreSQL database infrastructure components that allow GitLab.com to scale reliably while supporting hundreds of thousands of concurrent users.
Respond to production incidents and platform emergencies, working with peer SREs to diagnose and resolve database-related issues quickly and thoroughly.
Build observability systems that monitor database health, predict capacity needs based on usage patterns, and alert on symptoms rather than outages.
Develop and ship database performance solutions in collaboration with product and engineering teams, including query optimization, migration reviews, and infrastructure recommendations.
Create self-service tools and automation, using Terraform, Ansible, Chef, and GitLab ChatOps, that empower engineering teams to manage their own database interactions safely.
Document decisions, learnings, and operational procedures so that knowledge becomes repeatable actions and eventually becomes automation.
Participate in regularly scheduled on-call rotations to ensure GitLab.com remains operational during off-hours and weekends when necessary.

Hands-on experience running PostgreSQL in high-growth, large production environments, including both self-managed infrastructure and database-as-a-service platforms.
Expertise with infrastructure automation and configuration management tools such as Ansible, Terraform, Chef, or Puppet to automate operational tasks and drive system reliability.
Solid understanding of SQL, PL/pgSQL, data modeling, and data structure design; ability to analyze PostgreSQL internals to troubleshoot and optimize systems.
Experience working in large-scale, distributed SaaS production environments where you've managed reliability, performance, and scalability challenges at significant scale.
Strong written communication skills and commitment to documentation; you thrive in remote, asynchronous environments and share knowledge effectively across your team.
Proactive, hands-on approach where you identify issues, take ownership of solutions, and contribute improvements to infrastructure and code.
Capability to mentor junior team members and develop deep expertise in your domain areas, then share that knowledge to help others grow.
Backend engineering experience with languages such as Ruby or Go, and/or familiarity with OLAP databases like Clickhouse.
Familiarity with Kubernetes and operators for managing database infrastructure and stateful services in containerized environments.
