Job description

35,000 – 40,000 PLN

Important: if an employer asks you to log into their system via iCloud or Google, send a code, an SMS or Telegram password, run some code, or install software — refuse. These are signs of fraud.

We are looking for Principal SRE Engineer to join a team working directly on a proprietary, business‑critical product in a fast‑paced and dynamic environment. This is a hands‑on role where you will have a real impact on system reliability, scalability, and technical direction.

The role

As a Principal Site Reliability Engineer, you will design, implement, and operate highly available and scalable systems built primarily on Kubernetes (AWS EKS). You will play a key role in setting technical standards, guiding engineers, and ensuring operational excellence across production environments.

You will work extensively with Terraform, ArgoCD, and GitHub Actions, applying GitOps principles and modern deployment strategies such as blue‑green, canary releases, and feature flagging. The role requires strong troubleshooting skills, a deep understanding of distributed systems, and active participation in production support when needed.
