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
