Senior DevOps Engineer

We are looking for an engineer to own our CI/CD platform and its AWS infrastructure for a large C++ codebase. Your goal is fast, reliable builds for every developer, backed by metrics.

• Own the GitLab CI/CD platform: pipeline design, speed, stability and cost
• Build reusable CI templates shared across 10+ projects
• Design and run AWS infrastructure for CI: autoscaling runner fleets on EC2/EKS, IAM, S3 storage
• Build monitoring and alerting for runners, storage, caches and build times
• Use metrics to find bottlenecks and reduce time-to-result
• Optimise C++ pipelines (Conan + CMake) for reproducible builds and predictable caching
• Keep CI secure with least-privilege access and short-lived credentials via Vault

• Deep experience with GitLab CI/CD: templates, extends, rules, needs, artifacts, cache, child and dynamic pipelines
• Experience running and tuning GitLab Runners (docker, shell, k8s): autoscaling, resource limits, concurrency
• Strong AWS: EC2, IAM, S3, VPC; EKS is a plus
• Prometheus, Grafana and ELK: metrics, dashboards, alerting and incident diagnostics
• Ability to find the root cause of a slow build from metrics (IOwait, NFS, cache hit ratio, runner saturation)
• Hands-on Conan, CMake and ccache in CI
• Ansible for configuration management
• Vault or a similar tool integrated with CI
• Strong Linux troubleshooting and a data-driven approach

Multi-region runners and caching Python or Go for automation
