Platform Engineer

Function

We are looking for a Senior Platform Engineer to join our client’s team and help drive the development and professionalization of their platform capabilities. In this role, you will contribute to designing, implementing, and maintaining a platform focused on self-service, automation, and an optimal developer experience. You will work closely with developers, security, operations, and architects to create a robust, scalable, and reusable environment.

The assignment has three main objectives:

• Build and stabilize the OpenShift platform as a reliable, scalable, and reusable platform capability.

• Increase Kubernetes maturity within application teams through enablement, guidance, and clear platform mechanisms.

• Embed platform engineering principles in day-to-day operations, both technically and organizationally, in close collaboration with architecture and product management.

Key Responsibilities

• Design, implement, and refine OpenShift cluster architecture across multi-environment setups, covering security, networking, storage, and lifecycle management.

• Develop reusable platform building blocks, such as standardized namespaces, policies, base Helm charts/operators, and deployment/runtime patterns.

• Implement a GitOps-first approach with Argo CD for platform and application configuration.

• Ensure platform stability, maintainability, and evolvability, including upgrades, versioning, and lifecycle management.

• Collaborate with infrastructure domains such as networking, security, observability, and databases to integrate platform capabilities.

• Guide application teams on containerization, Kubernetes deployments, and integration with platform services such as CI/CD, IAM, observability, and secrets management.

• Develop golden paths and opinionated defaults to standardize practices while allowing flexibility.

• Contribute to documentation, templates, and self-service flows via tools like Backstage and Git.

• Coach teams on ownership practices (“you build it, you run it”) within the platform boundaries.

• Collect user feedback, focus on scalability and repeatability, and help break down silos between infrastructure, platform, and application teams.

Ideal Candidate Profile

• Bachelor’s or Master’s degree in IT or equivalent experience.

• Proven experience in platform engineering and DevOps.

• Strong knowledge of container technologies such as Docker and Kubernetes.

• Experience with CI/CD tools like GitLab CI, Jenkins, Argo CD.

• Familiarity with cloud-native technologies such as Helm, Prometheus, and Grafana.

• Scripting and automation experience (Bash, Python, Terraform).

• Team player with a product mindset and strong focus on developer experience and change management.

• Fluent in Dutch or French, with passive knowledge of the second national language and English.
