New Job Opening: Software Engineer in Romsey, UK

Job Description

Software Engineer

The Opportunity

This is the kind of environment that attracts engineers who want to stay close to meaningful technical work without disappearing into heavily layered delivery structures.

The organisation operates across the UK National Security and Defence ecosystem, delivering operational capability within RF communications, sensing and secure technology programmes. The work combines long-term product engineering with R&D-style problem solving, often within high-side environments where technical quality and engineering judgement carry real weight.

Teams are typically smaller and flatter than larger primes, giving engineers broader project exposure, more ownership and greater influence over technical direction. Software engineers work closely with systems specialists, DSP engineers and programme leadership rather than operating inside narrow delivery silos.

The environment suits engineers who enjoy variety and multidisciplinary collaboration. Depending on the programme, the work can span embedded Linux, DSP implementation, modern UI engineering, DevOps tooling and wider software modernisation initiatives.

The Role

You’ll be joining an agile software team responsible for developing and evolving software across RF communications and sensor-based products used within operational National Security and Defence environments.

The role sits close to both product engineering and technical decision-making, with engineers contributing across design, implementation, testing and ongoing capability development. Depending on your background and interests, the work can flex toward embedded software, modern UI engineering or wider platform and tooling development.

• Teams work collaboratively with Product Owners, System Design Authorities and multidisciplinary engineering groups, so the role suits people who are comfortable contributing technically while also engaging in broader engineering discussions and trade-off decisions.


•  Designing and implementing software components for sensing and communication systems using C++, C# and Python.


• Supporting product development across the full engineering lifecycle from early R&D concepts through to operational delivery and testing.


• Contributing to modern software architecture approaches within Agile delivery environments using Scrum and Kanban methodologies.


•  Implementing scientific and DSP-focused functionality, including algorithm integration within operational systems.


• Developing embedded Linux software including cross-compilation, deployment activities and low-level system tooling.


• Building and improving CI/CD workflows using GitLab pipelines, Docker and modern DevOps engineering practices.


• Working collaboratively within Git-based engineering environments using GitLab, Git and VS Code tooling.


• Supporting modern UI development and user-facing operational software where programmes require frontend capability

This environment tends to suit engineers who enjoy breadth as much as depth. The team is less focused on finding somebody who perfectly matches a single stack, and more interested in people who are technically curious, adaptable and comfortable working across disciplines when needed.

Strong communicators generally do well here because engineers are trusted to contribute beyond pure implementation. That could mean influencing technical direction, collaborating across multidisciplinary teams or helping shape how products evolve over time.

It is also a strong fit for engineers who prefer engineering autonomy and collaborative technical cultures over highly siloed delivery environments.

Security Requirements

Active SC clearance preferred. Candidates must be eligible and willing to undergo higher levels of UK National Security vetting where required.
