Job description

Systems Engineer / Systems Integrator – Mission Systems (Junior to Principal) – Bristol (Hybrid)

We’re hiring Systems Engineers and Systems Integrators at all levels to join our mission‑focused engineering team in Bristol, UK. These roles suit people who enjoy hands‑on engineering, rapid integration and delivering robust systems into demanding environments. We operate a hybrid model, typically around three days a week in the office, and welcome applicants within a commutable distance of Bristol.

Department: Engineering

Location: Bristol, UK

Compensation: £30,000 - £85,000 / year

About the Roles

As we grow, we’re looking to expand our team of engineers who specialise in systems engineering and systems integration. You’ll work across diverse capabilities and tech domains, playing a pivotal role in designing and delivering sophisticated, high‑stakes systems and working closely with colleagues who share a practical, delivery‑driven mindset.

Junior Systems Engineers and Systems Integrators

Salary: £30,000 - £40,000 (dependent on experience)

If you’ve got a couple years of experience and are keen for change, this could be your next step. At Rowden, junior engineers don't just sit on the sidelines. You’ll work directly on system components, build prototypes and support integration activities. Expect a mix of design, testing and hands‑on engineering across areas such as sensor integration, tactical networks and uncrewed systems. You’ll learn quickly and contribute to operational deployments early in your time with us. If you want to learn by doing and make your mark on projects that matter, we’d love to have you on the team.

Mid‑Level Systems Engineers and Systems Integrators

Salary: £40,000 - £55,000 (dependent on experience)

At Rowden, you’ll take ownership of key system elements, lead integration tasks and support architecture development. You’ll work across disciplines, solve technical issues and guide junior colleagues. Your role spans design, analysis, integration and delivery of systems into service, bridging the gap between innovative ideas and robust, real‑world solutions.

Senior Systems Engineers and Systems Integrators

Salary: £55,000 - £70,000 (dependent on experience)

If you’re an experienced systems engineer or integrator ready to lead and inspire, Rowden offers you the chance to shape the direction of our most complex projects. As a senior, you’ll architect end‑to‑end solutions, oversee technical delivery and provide strategic guidance across multiple programs. You’ll mentor and develop the next generation of engineers while fostering collaboration with stakeholders at all levels. Your expertise will drive innovation, help navigate ambiguity and ensure delivery of high‑assurance systems that meet demanding requirements.

Principal Systems Engineers and Integrators

Salary: £70,000 - £85,000 (plus dependent on experience)

As a Principal at Rowden, you could be the technical lead for our largest and most ambitious programs, orchestrating solutions across both technical and programmatic boundaries, leading critical, high‑risk areas of development and deployment or spearheading the technical direction of new opportunities alongside our sales team. You’ll lead the technical strategy for major programmes, support pre‑sales and solution development and oversee delivery across multiple technical areas. You’ll work with partners and end users, de‑risk complex integration challenges and champion engineering quality and continuous improvement.

Key Skills & Experience

• Translating user needs and CONOPS into system requirements
• Applying systems engineering lifecycles in varied contexts
• Designing, building and deploying systems into operational settings
• Assessing trade‑offs and explaining decisions clearly
• Reviewing technical work and identifying key risks
• Ensuring solutions meet safety, security and environmental standards
• Communicating complex ideas in plain language
• Staying adaptable, curious and hands‑on

Highly Desirable Skills and Experience

• Degree level qualification (or equivalent experience) in a relevant STEM subject
• Knowledge of Government engineering and procurement
• Knowledge of Agile development lifecycles and model‑based systems engineering approaches
• Knowledge of one or more of:
  • SysML, Enterprise Architect
  • Tactical networked C4ISR systems
  • Autonomous platforms
  • Cloud technologies
  • Machine learning
  • Safety and security assurance
