Help keep mission-critical systems performing where they matter most.

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.

What You Will Do

You will provide technical support and sustainment for deployed systems, helping ensure they continue to perform reliably and in line with company processes, procedures, and quality standards, including support for AS9100 accreditation.

You will support programs during the build phase of complex systems, including hardware assembly, software installation, and system configuration.

You will plan and carry out testing on newly built and upgraded systems, including Integration Testing, Factory Acceptance Testing and System Acceptance Testing
.

You will provide office-based technical support to customers by phone and email, with occasional out-of-hours support by prior arrangement.

You will travel within the UK and overseas to deliver, commission, upgrade, diagnose and resolve issues on systems originally built in Malvern.

You will work across a broad technology stack, including Microsoft products, Linux distributions, Active Directory, certificates, networking, storage solutions, and virtualisation
.

You will maintain locally held replicas of customer systems, using them for troubleshooting, upgrade testing, and issue resolution.

You will demonstrate software and systems to internal and external customers, while contributing to continuous improvement and lean activities.

What You Will Learn

You will build deep, practical experience across a wide range of technologies, including Microsoft and Linux platforms, networking, storage, virtualisation, Active Directory, and certificate management.

You will learn how complex, secure, multi-server systems are built, tested, deployed, and sustained throughout their lifecycle.

You will gain exposure to UK and international customer environments, seeing how systems are used operationally and how best to support them.

You will develop your skills in system testing, troubleshooting, and root cause analysis on live and replicated customer systems.

You will strengthen your communication and stakeholder management skills through regular engagement with internal teams and external customers.

What You Will Bring

We are looking for someone with experience in IT systems, system administration, technical support, or a similar technical environment.

You will have familiarity with setting up, configuring, and maintaining systems involving multiple servers and clients.

You will bring a basic understanding of Microsoft technologies, Linux systems and infrastructure concepts such as networking, storage, and virtualisation.

You will be comfortable solving technical problems independently, including when travelling or supporting customers abroad.

You will have strong written and verbal communication skills, with the ability to build effective relationships with colleagues, customers, and technical teams.

You must be willing and able to travel within the UK and overseas and occasionally provide out-of-hours support with prior notice.

You must be able to obtain and maintain the relevant UK security clearance required for the role,
