Job description

We are looking for a Senior DevOps Engineer to join our client, an international product company providing high-scale platform solutions for the iGaming industry.

This is an additional hire to strengthen an existing DevOps team, not a replacement. The team is looking for a strong hands-on engineer who can not only maintain production infrastructure but also independently troubleshoot complex issues, identify areas for improvement, and contribute new ideas and solutions.

What you’ll be doing

• Collaborate closely with DevOps and development teams.

• Review the existing infrastructure and plan improvements.

• Troubleshoot and resolve production incidents.

• Improve infrastructure reliability, security, and observability.

• Support and evolve Kubernetes-based production environments.

• Introduce and implement new tools and technologies.

• Contribute to infrastructure and architecture discussions.

• Proactively suggest solutions based on evolving product and business needs.

What we’re looking for

• Around 5+ years of hands-on DevOps / Cloud Infrastructure experience, with a strong Senior-level skill set.

• Strong practical experience with AWS — must-have.

• Solid production experience with Kubernetes — essential.

• Strong cloud infrastructure background rather than primarily on-premise experience.

• Experience with Infrastructure as Code, preferably Terraform / Terragrunt.

• Hands‑on experience with Docker.

• Experience building and maintaining CI/CD pipelines.

• Strong knowledge of Linux, networking, and HTTP.

• Proven experience troubleshooting production environments and handling incidents.

• Experience working as part of a DevOps/engineering team and collaborating closely with developers.

• English at B2 level or higher.

Experience with ArgoCD, Helm, Ansible, GitLab CI, Prometheus, Grafana, OpenSearch, Alertmanager, or DigitalOcean would be a plus.

Tech Stack

AWS, DigitalOcean, Kubernetes, Docker, GitLab/GitLab CI, ArgoCD, Terraform/Terragrunt, Helm, Ansible, OpenSearch, Grafana, Prometheus, Alertmanager.

Team & Working Environment

You will join a growing team of 6 DevOps Engineers, including the Team Lead. The company also has a separate SRE team of 7 engineers.

The role is fully remote and full-time, with required overlap during European core working hours.

There is no traditional 24/7 on-call rotation or continuous after-hours monitoring. Each week, one team member is responsible for assisting with production incidents if needed, with typically 0–2 incidents per week.

This role is offered on a B2B/contractor basis.

What the company offers

• Fully remote work.

• Paid vacation and sick leave.

• Corporate laptop.

• Private medical insurance reimbursement of up to €80/month after probation.

• Flexible benefits reimbursement of up to €100/month after probation.

• Career growth and professional development opportunities.

• Company-sponsored team events.

• Additional funding opportunities for education and personal development.
