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.

Responsibilities

• 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

Requirements

• 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

Nice to have

• Multi-region runners and caching

• Python or Go for automation

• Kafka

What we offer

• Result-oriented bonuses on top of a highly competitive salary

• Transparent processes and no red tape

• Real ownership of the platform

• A team with one of the highest levels of expertise on the market

• Relocation support to Cyprus
