Senior Kubernetes Engineer

About the role

As a Kubernetes Senior Engineer, you will build and operate the infrastructure layer that every engineer at Trade Republic depends on to deploy and scale their services with confidence.

What you'll do

• Build for availability: Implement and improve the cluster topology and isolation model that gets mission-critical services to their availability targets - dedicated clusters per criticality tier, strict failure boundaries between platform and product workloads, and disaster recovery procedures you help test and prove.
• Work across the networking fabric: Build and maintain the multi-account network the fleet runs on - VPC design, private endpoints, and cross-account connectivity - and contribute to the path toward cross-region and multi-cloud.
• Push toward zero-touch fleet operations: Build the automation that turns cluster and addon management into self-healing workflows, freeing the team from repetitive operational toil.
• Strengthen the compute contract with product teams: Implement the resource policies, cluster profiles, and workload isolation boundaries that define how workloads run on the platform.
• Own what you build end to end: Participate in the on-call rotation, taking operational ownership of the systems you build and run.
• Contribute to the platform's direction: Bring strong technical input to the Kubernetes platform's evolution and weigh infrastructure decisions against reliability, compliance, and cost.

What you'll need

• 5+ years of experience in infrastructure, platform engineering, or a related SRE/systems discipline.
• Deep, hands-on Kubernetes expertise: cluster architecture, scaling, security, and HA design in production environments.
• Strong networking fundamentals: CNI, ingress, DNS, service mesh, and cross-region/cross-cloud connectivity.
• Experience operating multi-region and/or multi-cloud environments in production.
• Experience automating the cluster lifecycle - provisioning, upgrades, policy, and governance - with self-service enablement for developers.
• Solid backend engineering background - Go is preferred but any strong language is welcome.
• A pragmatic approach to applying infrastructure best practices in a way engineering teams actually adopt.

Nice to have

• Ability to contribute to architectural decisions and clearly communicate trade-offs.
