Job Description

Infrastructure Engineers (Mid–Senior) | Farnborough | £65,000–£80,000 | SC Cleared

Momentum. Investment. Big, complex projects landing and a pipeline that keeps building. If you’re an Infrastructure Engineer who wants to work in the defence industry who thrives when things are busy, evolving and technically stretching, this is the kind of environment where you’ll genuinely grow.

This organisation operates at the top end of National Security and Defence, delivering secure-by-design solutions across multi-classification environments. With new work being won and existing programmes expanding, they are hiring both mid-level and senior engineers to strengthen an experienced, high-performing team.

You’ll be maintaining, improving and securing virtualised, collaboration and development environments across public, private and hybrid cloud platforms. Expect hands-on involvement in Windows Server (2016+), Linux (CentOS/RedHat/Ubuntu), VMware, Azure and Microsoft 365, alongside patching, monitoring, automation and incident management within protectively marked environments.

Senior engineers will also bring experience across networking, automation (PowerShell/Ansible), OpenShift/Kubernetes and DevSecOps tooling, while contributing to technical direction and supporting business growth.

Desirable exposure includes Terraform, Vault, Elastic, Nessus, application packaging and Agile delivery environments.

You would need to be eligible for Security Clearance during onboarding.  This would be on site in Farnborough.

If you’re looking for a role where there’s real technical depth, visible impact and a steady stream of meaningful projects to get stuck into, this is a brilliant time to join and make your mark.
