Candidate profile

Are you a Linux expert with a passion for automation and next-gen infrastructure? We’re looking for a skilled Linux Infrastructure Engineer to help architect, deploy, and maintain robust, scalable systems that power high-availability services across our organisation.

In this role, you’ll play a critical part in transforming how we deliver infrastructure—applying automation, containerisation, and infrastructure-as-code (IaC) to streamline operations and drive performance. You’ll work at the heart of our infrastructure strategy, enabling data-driven decisions and resilient platform delivery.

What You’ll Be Doing:

• Designing and implementing scalable, secure Linux-based infrastructure.

• Driving automation and efficiency through tools like Ansible, Terraform, and CI/CD pipelines.

• Supporting containerised environments and modern DevOps practices.

• Monitoring, optimising, and enhancing system performance using data insights and analytics.

Required qualifications to be successful in this role

• Proven expertise in Linux system engineering, with hands-on experience in complex infrastructure environments.

• A strong foundation in automation, scripting, and IaC methodologies.

• Familiarity with containers (Docker, Kubernetes) and supporting tools.

• A mindset geared toward resilience, scalability, and continuous improvement.
