We are looking for a Senior Platform / DevOps Engineer to join our existing Platform team. They run a modern AWS + Kubernetes platform, but we also integrate with traditional / on-prem infrastructure.

You will help design, build and operate the core platform used by our product teams: Kubernetes clusters, networking, observability, GitOps, and infrastructure as code. Working closely with other platform engineers and the Lead DevOps Engineer, owning specific areas and driving improvements end-to-end.

In addition, you'll be responsible for the following task:

Platform engineering

• Design, build and operate our AWS- and Kubernetes-based platform.

Cloud & Kubernetes

• Operate production AWS environments (multi-account, multi-environment).
• Operate Kubernetes clusters (upgrades, capacity, reliability, security).

GitOps & delivery

• Design and maintain Argo CD–based GitOps workflows (multi-cluster, multi-env).
• Contribute to CI/CD patterns and deployment strategies together with the team.

Observability

• Evolve and operate our observability stack:
  • Metrics: Prometheus, Thanos
  • Logs: Grafana Loki
  • Traces: Grafana Tempo
  • Instrumentation: OpenTelemetry
• Help define SLOs, dashboards and alerting that are actually useful for teams.

Networking & connectivity

• Work on Kubernetes networking, Ingress controllers and traffic routing.
• Contribute to designs using Envoy (or Envoy-based components), API gateways and SD-VPN solutions.

Infrastructure as Code

• Build and maintain Terraform modules and state layouts for AWS, Kubernetes and related infrastructure.
• Help migrate existing/manual infrastructure to Terraform with minimal disruption.
• (Bonus) Use Crossplane where it makes sense for Kubernetes-driven provisioning.

Hybrid & on-prem integration

• Support connectivity and integration between cloud workloads and on-prem systems.

Collaboration

• Work as part of the existing Platform team, participate in design reviews, incident reviews and on-call.
• Support product teams as internal customers by providing clear platform interfaces, documentation and examples.

Experience:

• 10+ years of experience in infrastructure / operations / platform / DevOps roles.

  • Networking (VPC, subnets, routing, security groups, load balancers).
  • Landing Zones
  • IAM and security best practices.
• Strong experience with Kubernetes in production:
  • Operating clusters (EKS or similar).
  • Workloads, deployments, autoscaling, upgrades and cluster lifecycle.
• Solid observability experience with at least several of:
  • Prometheus, Thanos, Grafana.
  • Grafana Loki, Grafana Tempo or similar logging/tracing systems.
  • OpenTelemetry for metrics/logs/traces instrumentation and pipelines.
• Solid networking knowledge:
  • TCP/IP, DNS, TLS, HTTP, routing, VPNs, firewalls, load balancing.
  • Experience with Envoy (directly or via service mesh / API gateway), Ingress controllers and API gateways.
• Experience with SD-VPN solutions (e.g. AWS VPN, Tailscale or similar).
• Strong experience with Terraform and Terragrun:
  • Modular design, state management, remote backends.
  • Managing AWS/Kubernetes infrastructure as code at team or org scale.
• Hands-on experience with Argo CD and GitOps principles:
  • Application structure, app-of-apps patterns, promotion across environments, RBAC and ABAC.
• Experience with traditional/on-prem infrastructure (VMs, networks, VPNs, storage, legacy systems) and connecting it to cloud environments.
• Comfortable working in a remote-first environment in European time zones (good written communication, async collaboration).

Nice to have:

• Experience with Crossplane in production.
• Experience in a Platform/Enablement team serving multiple product teams..
• Experience with Argo Workflows or similar workflow/orchestration tools.
• Experience with AWS Control Tower and Account Factory
