DevSecOps Engineer – Kubernetes

Have you set up Kubernetes from scratch and run it in production, down to troubleshooting the networking? Are you ready to keep an existing Docker Swarm platform running while working closely with colleagues to develop its successor? Join a software company in a security-critical sector to help build and secure its Kubernetes platform.

We are looking for a DevSecOps Engineer to maintain the current container platform and lead the development of its Kubernetes successor. You are a hands-on, dependable team player who can take ownership of complex technical work and explain solutions clearly.

🏅 What's in it for you

• Shape a Kubernetes platform from the ground up and influence how it evolves.
• Tackle the distinct challenge of building a secure platform for highly restricted environments, working with a broad technology stack and complex infrastructure.
• A long-term role at the heart of one of the company's most important technical changes.
• Open to both freelance consultants and payroll employees.

💼 What you will do

• Maintain and troubleshoot the existing Docker and Docker Swarm platform, including deployments already in use by clients.
• Design, build and operate the Kubernetes platform, and lead the migration from Docker Swarm.
• Automate platform, deployment and operational processes as code, and maintain and improve CI/CD workflows.
• Apply security hardening and compliance requirements, and support secure deployments across connected and restricted environments.
• Troubleshoot complex issues across applications, containers and infrastructure.
• Work closely with development, architecture and infrastructure colleagues to improve reliability, scalability and performance, and enable teams to use and maintain the platform effectively.

🎯 Who you are

Must-haves

• Have set up Kubernetes clusters from scratch, not only worked on an existing cluster.
• Have the depth to operate Kubernetes and troubleshoot issues, including cluster networking (CNI, DNS, ingress).
• Have strong Linux experience.
• Be able to support and troubleshoot Docker and Docker Swarm from day one.
• Have experience with GitOps, CI/CD and infrastructure automation (e.g. Argo CD, Jenkins, Ansible).
• Have experience in highly regulated or security-critical environments.
• Work well across teams and communicate solutions clearly.

📌 Practical information

• Location: Brussels Region
• Contract type: Freelance, or on recurv payroll
• Homeworking: Up to 3 days per week

This is a rare chance to build a critical Kubernetes platform from the ground up and make it your own. If that's the challenge you've been looking for, we'd love to hear from you.
