* Influence senior stakeholders, architects, security teams, and delivery leads on platform strategy, risk, and investment priorities
Infrastructure as Code & Automation Delivery
* Design, build, and maintain Infrastructure as Code (IaC) for the automated provisioning and lifecycle management of on‑premise CWEs
* Develop reusable, version‑controlled automation artefacts to standardise infrastructure builds across environments
* Lead the transition from manual and bespoke builds to repeatable, code‑driven infrastructure delivery
* Ensure all infrastructure changes are auditable, reproducible, and aligned with secure delivery practices
Security, Assurance & Compliance
* Embed defence‑grade security controls, identity integration, and configuration hardening into all automation
* Design infrastructure automation to support accreditation, assurance, and audit requirements
* Work closely with security and compliance teams to ensure platforms meet customer and regulatory expectations
CI/CD & Environment Lifecycle Management
* Integrate Infrastructure as Code into CI/CD pipelines to support controlled, repeatable platform changes
* Define and implement safe promotion models across development, test, and production environments
* Automate environment provisioning, modification, and decommissioning to support customer lifecycle needs
Operational Reliability & Continuous Improvement
* Improve reliability and reduce operational risk by identifying automation gaps and replacing manual processes
* Support incident analysis and drive preventative improvement through enhanced automation
* Actively manage technical debt within platform automation codebases
* Continuously refine automation to improve efficiency, quality, and resilience
Leadership, Coaching & Enablement
* Provide senior technical leadership and mentoring to Junior and Graduate engineers
* Set expectations for coding quality, automation practices, and operational ownership
* Enable delivery and operations teams to safely consume platform automation through clear guidance and tooling
* Contribute to engineering culture, promoting automation‑first, code‑driven delivery
Essential Experience
Education and Experience Requirements
* Significant, hands‑on experience designing, building, and operating on‑premise infrastructure platforms within enterprise or highly regulated environments
* Proven experience delivering Infrastructure as Code (IaC) to automate the provisioning and lifecycle management of infrastructure
* Demonstrable experience working in security‑constrained or regulated environments, such as defence, government, or critical national infrastructure
* Experience contributing to or establishing technical standards, automation patterns, and strategic direction for platform engineering
Technical Experience
* Strong experience with Nutanix hyperconverged infrastructure, including cluster design, operation, and automation
* Experience supporting or automating Citrix platforms (e.g. virtual apps and desktops) within secure enterprise environments
* Solid understanding of traditional data‑centre technologies including compute, storage, networking, and identity services
* Hands‑on experience building, configuring, and automating SQL Server platforms
* Experience supporting multi‑tier enterprise applications hosted on on‑premise infrastructure
* Understanding of how collaboration platforms are underpinned by identity, database, and application services
Automation & Infrastructure as Code
