Job description

Working Environment

You'll work on real, live systems where delivery quality, operational reliability, and adaptability matter more than theoretical knowledge. Collaboration across engineering, platform and architecture teams is expected, with a strong emphasis on ownership and pragmatism.

What You'll Be Doing

• Design, deploy and operate platforms and services on Kubernetes-based environments
• Manage deployments using Helm, with supporting infrastructure defined through tools such as Terraform
• Own systems and applications through their full lifecycle, from deployment to live operation and support
• Ensure systems are supportable, secure, monitored and reliable in production
• Configure and operate machine learning workloads in production, focusing on running models rather than training
• Monitor system performance, identify issues and troubleshoot problems in live environments
• Work closely with engineers, architects and stakeholders to deliver integrated platform solutions
• Contribute to improving DevOps, platform and operational practices across teams

Your Experience

• Strong experience as a DevOps Engineer, Platform Engineer or similar senior hands-on role
• Proven experience deploying and operating systems on Kubernetes platforms
• Strong hands-on experience with Helm for managing application deployments
• Experience managing systems through their full operational lifecycle
• Solid understanding of monitoring, supportability and reliability concerns in production
• Experience using infrastructure-as-code tools such as Terraform
• Confidence taking responsibility for live systems and outcomes

MLOps experience is highly attractive, particularly operating AI or machine learning models in production. The focus is on operating models, not training them.

In Return

You'll work on platforms that support AI and data-driven capabilities in real production environments.

This is an opportunity to deepen hands-on expertise, own systems end-to-end, and contribute directly to reliability and delivery outcomes.
