IT Site Reliability Engineer
At GitLab, the IT Infrastructure team is responsible for Site Reliability Engineering for our tech stack applications and cloud infrastructure that supports corporate initiatives across many of our departments. In addition to traditional AWS and GCP administration, we also provide escalation engineering support for departments that manage their respective SaaS tech stack applications (vendor hosted). Another of our functions is to provide DevOps Engineering for several internally built applications that power our business operations and automation.
The IT team collaborates closely with the Engineering Infrastructure Reliability team that is responsible for our GitLab.com SaaS platform (our product infrastructure). The IT, Engineering, and Infrastructure Security teams collaborate to architect, implement, and manage our AWS and GCP infrastructure policies and collectively manage all related services.
- Lead the handling of ticket queue (GitLab issues) for AWS and GCP corporate infrastructure requests from team members. This ranges from simple IAM and DNS requests to designing and deploying new scalable application infrastructure.
- Design, build and maintain core infrastructure that enables GitLab can scale to support 2,000+ team members and the applications and services that they use day-to-day.
- Implement and maintain system logging and monitoring to alert on problems and prevent outages, and get ahead of customer needs.
- Maintain the corporate AWS and GCP infrastructure utilizing Ansible, Terraform, GitLab CI/CD, and Kubernetes
- Gather and analyze operating system and application metrics to assist in performance tuning and fault finding
- Create sustainable systems and services through patching, automation, and upgrades
- Document every action so your findings turn into repeatable actions and then into automation.
- Provide mentorship to IT System Administrators and IT Analysts who have an interest in infrastructure and IaC.
- Collaborate with other teams to improve services and help with system design, platform management, and capacity planning
