Description:

The role is part of the global Platform Engineering team at Portainer, focusing on ensuring the reliability, scalability, and efficiency of large-scale, self-managed Kubernetes environments across customer data centers.
The engineer will work directly with customer platform teams to operate and improve their Kubernetes estate, enhance observability and automation, and extend platform capabilities via Portainer and complementary tools.
This position is high-impact and requires a blend of deep infrastructure knowledge, cloud native expertise, and a DevOps/SRE mindset to support mission-critical systems across global time zones.
The ideal candidate has extensive experience in operating and engineering Kubernetes at scale, having faced real-world incidents and solved complex infrastructure problems.

Requirements:

Candidates must have 6+ years of hands-on experience in Platform Engineering, DevOps, or SRE roles.
A minimum of 3+ years operating large-scale on-prem or self-managed Kubernetes clusters in production is required.
A deep understanding of Kubernetes control-plane components (API server, etcd, controller-manager, scheduler) is essential.
Experience with Portainer or other Kubernetes platform management tools (e.g., Rancher, Lens, OpenShift) is necessary.
Proficiency in service mesh technologies such as Istio and Envoy is required.
Demonstrable experience in Go is a strong advantage, particularly in building custom Kubernetes operators or contributing upstream.
Advanced skills in Infrastructure as Code (Terraform, Helm, Kustomize) and GitOps workflows are needed.
Solid knowledge of CNI plugins (e.g., Cilium, Calico), ingress controllers, and CSI drivers is important.
Candidates should have scripting and automation experience using Python, Ansible, Terraform, or Bash.
Familiarity with observability tooling (Prometheus, Grafana, Loki, VictoriaMetrics, Mimir, etc.) is required.
A strong grasp of reliability engineering principles, including SLOs, SLIs, chaos testing, and scaling patterns, is essential.

Portainer offers a highly competitive salary as part of its broad benefits package.
Employees have the ability to work anywhere in the world while being part of a dynamic team.
The company provides opportunities to tackle some of the most interesting challenges in the technology/infrastructure space.
