Senior Kubernetes Engineer

Please note: We are not able to consider candidates who are not living and working in the Netherlands. At this moment we are not providing relocation sponsorships.

At Schuberg Philis, we specialise in mission-critical IT, partnering closely with our customers to ensure their most vital systems run smoothly and securely. Our engineers are T-shaped professionals who thrive at the intersection of depth and breadth, combining deep expertise in their fields with a collaborative mindset to ensure 100% customer satisfaction.

Working within dedicated, cross-functional, self-steering Customer Teams, we take ownership of complex challenges, co-creating solutions that align with our customers’ goals. From designing and building robust systems to managing secure, business-critical platforms. Furthermore, we automate as much as possible, support the (customer) team and developers on applications, and keep the platform secure, up to date, and available.

As a Senior Kubernetes Engineer, you will collaborate with both your team and customer engineers to administer, monitor, and manage all customer Kubernetes clusters running on Amazon EKS across DTAP environments. You will ensure the clusters’ stability, security, and scalability while driving automation, supporting incident response, and enabling continuous improvement of infrastructure and processes.

What will you do

Responsibilities vary, but may include:

• Collaborate closely with your team and customer engineering teams to ensure smooth operation and alignment across all Kubernetes-related initiatives.

• Perform administration, maintenance, and troubleshooting of all customer Kubernetes clusters deployed on Amazon EKS across DTAP (Development, Testing, Acceptance, Production) environments.

• Implement, monitor, and maintain cluster health, performance, and reliability, proactively identifying and resolving issues to minimise downtime.

• Manage and execute change management processes for Kubernetes clusters, including upgrades, scaling, and configuration changes, while ensuring compliance with internal policies and best practices.

• Develop, maintain, and optimise monitoring, alerting, and logging solutions for Kubernetes infrastructure using industry-standard tools.

• Automate routine administrative tasks and operational workflows using scripting or Infrastructure-as-Code (IaC) solutions.

• Maintain comprehensive documentation for cluster setups, architectures, processes, and change histories, ensuring knowledge sharing within the team.

• Enforce security best practices, ensuring clusters are compliant with organisational standards and external regulations.

What you’ll bring

• Minimum of 2 years of hands-on experience managing Kubernetes cluster lifecycles, including cluster provisioning, upgrades, vertical and horizontal auto-scaling, high availability setups, container networking configurations, security best practices, and disaster recovery strategies.

• Proven experience operating Kubernetes in production environments on public clouds (especially AWS), covering services such as IAM (including RBAC), VPC and subnet networking, multi-account organisation, and observability implementations.

• Strong proficiency with Infrastructure as Code (IaC), Git and GitOps workflows, and self-hosted CI/CD pipelines.

Nice to have

• Familiarity with tools such as Karpenter, Cilium, Kyverno, or External Secrets Operator (ESO).

• Experience developing custom Kubernetes Operators.

• Hands-on experience with observability tools such as Datadog or Grafana.

• Programming and scripting proficiency in Bash, Go, or Python.
