Senior Software Engineer - Full Stack

Software Engineer (Full Stack)

Location: Milton Keynes (Hybrid - 2-3 days onsite)
Type: Permanent
Security Clearance: Current SC Clearance advantageous, but sponsorship is available for candidates eligible to obtain UK SC Clearance.

The Opportunity

This is a unique opportunity to join an ambitious and rapidly growing technology SME at an exciting stage of its journey. With a reputation for delivering innovative, mission-critical solutions to Government and Defence customers, the business is continuing to expand its engineering capability to support a growing portfolio of programmes and digital transformation initiatives being deployed across the UK public sector.

Working at the forefront of secure technology, data, and AI-driven innovation, you'll play a key role in developing solutions that help Government organisations make faster, smarter, and more informed decisions. The work is meaningful, technically challenging, and directly contributes to some of the UK's most important operational and strategic programmes.

Unlike larger organisations where you can become one of many, this environment offers the opportunity to have genuine influence. You'll work closely with highly skilled engineers, architects, and technical leaders, helping shape products, technical direction, and delivery approaches whilst building solutions that have a real-world impact.

For candidates looking to establish a career within the secure Government and Defence sector, this is also an excellent opportunity to obtain Security Clearance (SC) if not already held, opening doors to some of the UK's most exciting and high-profile technology programmes.

You'll be joining a highly collaborative and technically driven team delivering secure, innovative software solutions that support the evolving needs of Government and Defence organisations. The work spans complex operational environments, advanced data platforms, AI-enabled capabilities, and modern cloud architectures, providing plenty of opportunity to work with new technologies while solving genuinely challenging problems.

If you're looking for a role where you can make a tangible impact, gain exposure to high-profile Government programmes, achieve SC Clearance, and help shape the future of a growing technology business, we'd love to hear from you.
