Full job description

Great ideas come from different minds. That’s why we bring together engineers, scientists, analysts, and creatives from every background — and give them the trust, tools, and freedom to make a difference. What connects us is the mission: solving meaningful problems and building capability that protects what matters most.

And as the challenges evolve, so do we — working on the technologies that will shape tomorrow, not just today.

Backend Software Engineer - Network Analysis

Build mission-critical backend systems that help protect the UK.

Join Roke as a Backend Software Engineer working on high-performance network analysis platforms used in National Security environments.

We’re a leading technology and engineering company supporting customers across National Security, Defence and Intelligence, delivering systems that operate in the most demanding and sensitive environments. Our teams tackle some of the country’s most complex technical challenges - and as a Backend Software Engineer, you’ll be at the heart of solving them.

The mission

You’ll work on a network and packet analysis platform that processes high-volume data using technologies such as Python and Apache Pulsar.

This is critical to delivering mission-critical software used by National Security customers to keep the UK safe, secure and prosperous. You’ll work on the feature development and maintenance of critical systems in this area, solving complex, real-world problems.

What you’ll build

Write clean, secure and maintainable backend code in Python using the latest frameworks for processing large volumes of network data.
Apply best practices for version control and DevOps principles.
Translate designs into working software, from concept to production
Contribute to code reviews and shared technical decisions
Design, build, test and document robust backend services
Apply appropriate patterns using proven and emerging technologies
Stakeholder / customer engagement

Nice to have

Messaging or streaming technologies (e.g. Kafka or Apache Pulsar)
Network analysis / packet analysis domain experience
Tooling such as GitLab

Why join Roke?

At Roke, you’ll join a collaborative engineering community with the freedom to solve hard problems properly. We combine 70+ years of trusted delivery with the pace, curiosity and technical depth of a modern engineering business.

You’ll work with smart, supportive people on a project that genuinely matters, in an environment that values technical excellence and continuous learning. We invest in your growth, value diverse thinking and offer flexible working alongside a strong benefits package (including 30 days holiday plus bank holidays). Roke combines a 70+ year heritage with the agility to make a real impact.

Where you’ll be based

Romsey – a unique Manor House site near the New Forest and south coast, with on site parking and gym. We offer a free minibus service between Romsey train station and the office.

Security clearance

This role requires candidates to hold valid DV clearance. If you don’t currently hold DV but do meet the eligibility criteria, we’d love you to explore other engineering opportunities. Visit our Careers Page: https://www.roke.co.uk/careers/

Eligibility criteria: please refer to the gov.uk website for more information
