Job Overview

As an Infrastructure Automation Engineer, you will help design, develop, build and maintain automation solutions that keeps our engineering facing large-scale infrastructure running optimally.

We are a forward-looking team with early access to emerging technologies, crafting the tools and workflows later embraced across the organisation. Our team is hands-on and in this role will spend most of your time writing automation code, improving deployment pipelines, and reducing toil across cloud and on-premises environments.

We believe in automating everything to deliver measurable improvements, stitching sophisticated systems together with a combination of AI, APIs and pure technical wizardry

Responsibilities

• Develop and maintain Infrastructure as Code and Configuration as Code to provision and run services across hybrid environments, covering end-to-end operational workflows.
• Build CI/CD pipelines, ensure new infrastructure is observable from day one, and we manage secrets through enterprise-grade secrets management solutions.
• Hands-on experience with AI-assisted development tools - from code generation and refactoring to agentic AI workflows.

Required Skills And Experience

• Hands-on proficiency in Terraform, Ansible & AWS, backed by strong programming skills and a genuine curiosity about turning large-scale traditional infrastructure into clean, automated systems.
• A builder's perspective for hybrid architectures - comfortable designing automation across on-premises physical, virtual, cloud, containerised, and serverless environments.
