Position Purpose:  Join the Automation & Containers team to build, run, and continuously improve our Kubernetes-based platform. You’ll handle the usual operational support while driving platform evolution -scalability, performance, automation, and a great developer experience—so delivery is fast, secure, and auditable by default.

Primary duties will include: 

• Operate and evolve Kubernetes (Rancher/RKE2 or AKS): upgrades, scaling, performance tuning, cost/capacity management, backup/restore, and HA patterns.
• Design automation and golden paths: Terraform modules, Helm/Kustomize templates, reusable GitHub Actions workflows, and self-service onboarding.
• Implement and maintain GitOps with Argo CD: digest-pinned deployments, policy-as-code, image signing/SBOM, drift detection, safe rollbacks.
• Harden CI/CD: environment protections, approvals, OIDC-based cloud access, immutable audit trails; keep pipelines fast and compliant.
• Manage supply chain & registries (ACR): immutability, vulnerability scanning, promotion strategies.
• Own observability for the platform (Datadog/Prometheus, Graylog/Splunk): SLOs, dashboards, actionable alerts, and capacity hygiene (incl. ephemeral storage/emptyDir).
• Partner with dev/infra teams on onboarding, troubleshooting, runbooks, and incident response; participate in an on-call rotation.
• Uphold security & compliance guardrails (RBAC, secrets management, SoD, change controls) without slowing delivery.

To land this role you will need:

• 3+ years in Platform/SRE/DevOps roles with production Kubernetes experience.
• Hands-on with GitOps and modern CI/CD (example: Argo CD, GitHub Actions and/or Azure DevOps).
• Infrastructure as Code (Terraform), packaging (Helm/Kustomize), and solid Linux/networking fundamentals.
• Scripting for automation (Bash and/or Python); comfortable with YAML-first workflows.
• Experience operating logging/metrics/tracing stacks and troubleshooting complex distributed systems.

What makes you stand out: 

• Rancher/RKE2 or AKS depth; policy-as-code (Kyverno/Gatekeeper); cosign image signing & SBOM (Syft/CycloneDX).
• ACR governance, artifact promotion, and immutable tagging; self-hosted runner hardening.
• Exposure to SOX/SOC-aligned CI/CD controls and evidence practices.

Education:

• Bachelor's degree in Computer Science, or a combination of education and/or equivalent experience.

Working environment:

• Hybrid; our Cracow office is located at Mogilska 35 street.
• Parking space for employees.
