Above all, we are looking for someone who works closely with development teams and actively supports them in achieving their goals. This role is not about operating in isolation - it’s about partnership, enablement, and shared ownership.Strong technical skills matter, but they are not the top priority. We value clear communication, willingness to help, and a true team-player mindset far more.If you believe DevOps exists to empower developers rather than block them, you’ll fit in well here.Responsibilities: Collaborate closely with architects, developers, QA, and security teams to ensure smooth and reliable environment operations. Work in close partnership with the platform team, based on shared ownership, knowledge exchange, and mutual support. Own and operate containerized application platforms based on Docker and Kubernetes, ensuring reliability, scalability, and operational excellence. Design and deliver dynamic test environments at scale, including multiple parallel, per–merge request (branch-based) deployments. Build, maintain, and standardize CI/CD pipelines by creating reusable templates and components in GitLab CI. Drive deployment automation and GitOps practices Identify operational bottlenecks and implement automation to reduce manual effort and improve delivery speed. Embed security-by-design across the SDLC, including pipeline hardening and automated security checks. Build and operate observability platforms: monitoring, logging, and diagnostics (Prometheus, Grafana, ELK/EFK/Loki, etc.). Participate in on-call and incident response, including troubleshooting, root-cause analysis, and post-mortems. Take end-to-end ownership of the solutions you build (“you build it, you run it”).
