Raytheon UK is looking for a hands‑on Technical Support & Sustainment Engineer to join our team in Malvern, supporting complex IT systems used in defense, national security, and other critical environments.

This is a varied role for someone who enjoys getting under the bonnet of technology: building systems, testing upgrades, solving problems, supporting customers, and travelling to sites in the UK and overseas when needed.

You will work across the full lifecycle of secure, multi‑server and multi‑client systems, from build and configuration through to testing, deployment, sustainment, and upgrade. If you enjoy combining technical depth with real‑world impact, this role gives you plenty of room to grow.

• Familiarity with setting up, configuring, and maintaining systems involving multiple servers and clients.
• Basic understanding of Microsoft technologies, Linux systems and infrastructure concepts such as networking, storage, and virtualisation.
