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

Join the Mercury Platform Team and help build and run the group-wide cloud-native platform powering delivery teams across the organization. Our mission: a best-in-class developer experience, zero-friction deployments, and secure multi-cluster Kubernetes operations at scale. 

Why this role matters:

• High Impact: Your work directly enables delivery teams across the bank to ship services faster, more securely, and more reliably — from namespace provisioning to production promotion. 
• Modern Technology: Cloud-native, GitOps-driven, AI-enabled, and continuously evolving — this role will sharpen your skills in distributed infrastructure, automation, and platform engineering. 
• Close to Users: You'll work directly with development teams to understand their needs and build the right platform capabilities — from self-service APIs to progressive delivery pipelines. 

What you can expect:

• 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 (GitHub CoPilot, Claude Code etc.) 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 

What you bring to the table:

• Solid understanding of Kubernetes and cloud-native infrastructure patterns  
  E.g. experience with 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) 
• Coding skills in at least one of: Go, Python, or Java 
• Strong security mindset — identity management, encryption, and policy enforcement matter to you 
• Openness to explore the latest AI tech trends with us 

Nice to have: 

• Experience operating platforms for regulated or high-availability environments 
• Background in building internal developer platforms or self-service tooling 
• Agile/DevOps mindset and experience in cross-functional teams
