We’re expanding our Platform Engineering team and looking for three new colleagues with a shared foundation in Cloud, DevOps, and AWS, but each with a different area of focus.

Whether your expertise lies in Security & IAM, AI Development/Python, or FinOps & Cloud Cost Optimisation, we want to hear from you.

In your application, please indicate which area excites you most, and tell us how your experience and motivation align with it.

The role

As a Senior Platform Engineer, you’ll be part of a dedicated team that develops and maintains the platform foundation that empowers APS developers.

• Delivering and maintaining CI/CD pipelines.
• Develop and maintain observability features.
• Working closely with developers, tech leads, and business teams to align on architecture, best practices, and added value.
• Evaluating new tools, methods, and ideas to keep our platform modern, efficient, and sustainable.

FinOps / Cloud Cost Optimization

• Implementing and maintaining tagging strategies to enable visibility and cost tracking.
• Building dashboards to monitor and optimise cloud spending.
• Using data and automation to promote cost awareness across teams — including gamified approaches to encourage efficient usage.

What you bring

• Proven experience in AWS, Kubernetes, Terraform/Terragrunt, GitLab, and ArgoCD.
• Solid scripting/programming skills and an automation mindset.
• Understanding of CI/CD, Infrastructure as Code, and change management practices.
• Broad knowledge of infrastructure, networking, and cloud security.
• A team player with a curious mind and a drive for continuous improvement.

Nice to have
