• Contribute to infrastructure automation, scripting, and internal tooling

• Write clear post-incident reviews and contribute to the monthly operational report

What You Bring

• 4+ years in a DevOps / SRE / Platform Engineering role within an international team

• Solid Kubernetes knowledge - cluster operations, troubleshooting, and configuration

• Hands-on cloud experience with AWS and/or GCP

• Good understanding of networking fundamentals - DNS, load balancing, firewalls, VPC

• Scripting and automation skills (Python, Bash, or similar)

• Experience with CI/CD tools and GitOps-based delivery

• Working knowledge of monitoring and observability systems (Prometheus, ELK, or equivalent)

• Fluent English (C1 minimum) - daily communication with European stakeholders is a core requirement

• Self-directed and proactive - you ask the right questions and drive issues to resolution without waiting to be told
