Raytheon UK is looking for a hands-on Graduate 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:

• 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.
• Support programs during the build phase of complex systems, including hardware assembly, software installation, and system configuration.
• Plan and carry out testing on newly built and upgraded systems, including Integration Testing, Factory Acceptance Testing and System Acceptance Testing.
• Provide office-based technical support to customers by phone and email, with occasional out-of-hours support by prior arrangement.
• Travel within the UK and overseas to deliver, commission, upgrade, diagnose and resolve issues on systems originally built in Malvern.
• Work across a broad technology stack, including Microsoft products, Linux distributions, Active Directory, certificates, networking, storage solutions, and virtualisation.
• Maintain locally held replicas of customer systems, using them for troubleshooting, upgrade testing, and issue resolution.
• Demonstrate software and systems to internal and external customers, while contributing to continuous improvement and lean activities.

What You Will Learn:

• Build deep, practical experience across a wide range of technologies, including Microsoft and Linux platforms, networking, storage, virtualisation, Active Directory, and certificate management.
• Learn how complex, secure, multi-server systems are built, tested, deployed, and sustained throughout their lifecycle.
• Gain exposure to UK and international customer environments, seeing how systems are used operationally and how best to support them.
• Develop skills in system testing, troubleshooting, and root cause analysis on live and replicated customer systems.
• Strengthen communication and stakeholder management skills through regular engagement with internal teams and external customers.

Qualifications and Skills You Must Have:

• A degree in a relevant IT field, with work experience (such as a placement year) in a technical IT background.
• Curiosity with the ability to learn and to bring fresh ideas into business.
• Strong written and verbal communication skills, with the ability to build effective relationships with colleagues, customers, and technical teams.
• 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, SC at a minimum.

Qualifications We Would Prefer:

• A full UK driving license.

What we Offer:

In return we offer a benefits package which includes a competitive salary as well as 25 days annual leave plus bank holidays. There is an Employee Assistance Programme, option to buy and sell holidays, employee discounts, a fantastic pension scheme, discounted gym membership and much, much more. We provide exceptional career opportunities to exceptional individuals. Many of our Technical Support & Sustainment Engineers have progressed into different business departments like Engineering, Programme Management and Business Development.

Why Join Us?

This is a role with variety, visibility, and purpose. One week you could be working in the lab in Malvern, the next supporting a customer site, testing an upgrade, or helping resolve a complex technical issue. You will join a team that works at the sharp edge of system sustainment, where technical quality, reliability and customer trust are essential.
