Platform Engineer (f/m/x) - Mercury Runtime Platform

Join the Mercury Platform Team to design, build, and run a cloud-native, group-wide platform that accelerates delivery across the organization. You will create seamless developer experiences, enable zero-friction deployments, and manage secure multi-cluster Kubernetes at scale, turning platform capabilities into tangible business outcomes from namespace provisioning to production promotion.

This role combines high impact with hands-on engineering: you’ll work with cutting-edge, GitOps-driven and AI-enabled tooling to advance automation and distributed infrastructure, while collaborating closely with development teams to deliver self-service APIs and progressive delivery pipelines that directly address their needs.

Your mission:

• Build and operate a modern multi-cluster and multi-cloud Kubernetes platform (OKD/OpenShift on AWS, Azure, EU Cloud)
• Design and automate GitOps deployment pipelines with ArgoCD and Kargo
• Extend platform capabilities with Crossplane compositions and custom APIs
• Deep-dive into progressive delivery, service mesh (Istio), and policy enforcement (Kyverno)
• Use AI assistants and agents to accelerate engineering workflows
• Provide platform expertise and troubleshooting support to delivery teams
• Perform SRE work to keep multi-cluster environments stable, secure, and observable

Your core competencies:

• Solid understanding of Kubernetes and cloud-native infrastructure patterns (e.g., OKD/OpenShift, or similar self-operated K8s distros - operator development is a plus)
• Experience with GitOps tools (ArgoCD, FluxCD, or similar)
• Practical experience with Infrastructure as Code (Crossplane, Terraform, or similar)
• Knowledge of monitoring, logging, and alerting (Grafana, Prometheus, or similar)
• Practical experience with AWS or similar providers
• Solid coding skills in at least one of the following languages; Python preferred, or Go/Java
• Strong security mindset - identity management, encryption, and policy enforcement matter to you
• Openness to explore the latest AI tech trends with us
