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
