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.
• Mentor and upskill junior team members, leading workstreams and smaller teams across a set of ever evolving solutions allowing Arm to scale dynamically to meet all of our current and future engineering needs.

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.
• Excellent problem-solver and communicator with a consistent track record of bringing people together and helping diverse teams deliver outstanding results. If you think restarting a service or contacting a vendor is true support, this role probably isn't for you

Nice To Have Skills And Experience

• You have adapted to the dynamic changes in IT, from sysadmin to SRE or Software development and have supported a wide range of technologies, or been a specialist in one.
• Valid certifications that demonstrate expertise in both architecture and automation!
• Active technical presence in the community - through blogs, open-source work, or conference talks.
