Lead platform modernisation initiatives, moving from manual/legacy processes to automated solutions
Collaborate with development, platform, and security teams to deliver automated, reusable service offerings
Develop and maintain technical documentation, automation standards, and reusable patterns
Analyse and resolve complex platform issues, leveraging automation to prevent recurrence
Support capacity planning, performance optimisation, and cost efficiency through automation insights
Partner with 3rd parties and internal teams to align with industry best practices in DevOps and platform engineering
Contribute to continuous improvement of Agile delivery practices (Scrum/Kanban)
Experience
Strong experience delivering automation-led platform engineering initiatives, leading workstreams or domains
Proven track record implementing Ansible at scale across Unix/Linux estates
Experience building end-to-end automated pipelines (build, config, patch, deploy)
Hands-on experience with Infrastructure as Code and GitOps methodologies
Experience transforming legacy/manual operational processes into automated workflows
Ability to define automation strategy, standards, and reusable frameworks
Experience acting as a technical authority for Unix automation and platform engineering
Strong stakeholder engagement across engineering, operations, and leadership teams
