System Engineer - RF & Defence

Are you an experienced Systems Engineer looking to work on technology that really makes a difference? We're partnering with a leading organisation in the Defence & Security sector that is growing its team and looking for a talented engineer to help deliver some of the UK's most advanced Electronic Warfare (EW), RF communications, sensor systems, and Positioning, Navigation & Timing (PNT) solutions.

This is an exciting opportunity to take a leading role in the design and delivery of cutting-edge capabilities that support UK Defence and National Security programmes.

As a key member of the engineering team, you'll help shape complex technical solutions from concept through to delivery. Your responsibilities will include:

• Acting as the technical authority for complex defence technology programmes
• Leading systems engineering activities across the full lifecycle, from requirements definition and architecture through to integration, verification, validation, and acceptance
• Designing system architectures for EW, communications, sensor, and PNT solutions
• Providing technical leadership to multidisciplinary teams spanning hardware, software, firmware, RF, DSP, and FPGA engineering
• Managing technical risks, dependencies, trade-offs, and key engineering decisions
• Working closely with customers through technical reviews, workshops, and solution development activities
• Supporting bid work, future capability planning, and business growth initiatives
• Ensuring projects are delivered to agreed cost, schedule, performance, and quality targets
• Contributing to trials, demonstrations, and rapid prototyping activities when required

We're keen to hear from technically credible Systems Engineers who have experience delivering complex defence, aerospace, communications, or electronic systems.

• Experience with in Defence, Systems Engineering, Electronic Warfare, RF communications, or Combat Systems
• A degree in Engineering, Computer Science, Physics, Mathematics, or a related discipline
• Strong systems engineering expertise across the full product lifecycle
• Experience leading technical teams and making high‑level system design decisions
• Knowledge of RF communications, sensor systems, or complex electronic systems
• Strong stakeholder management and customer engagement skills
• The ability to balance technical, commercial, and operational requirements to deliver effective solutions

It would be great if you also have experience in any of the following areas:

• Electronic Support (ES), Electronic Attack (EA), ESM, or ECM technologies
• Software Defined Radios (SDR)
• Digital Signal Processing (DSP)
• FPGA-based systems
• RF cyber capabilities
• Military communication systems and radio bearers
• Open standards such as SOSA, OpenVPX, MORA, STICS, or OpenCPI
• Agile, SAFe, Waterfall, or Spiral delivery methodologies
• Defence, Intelligence, or National Security programmes

In return, you'll have the opportunity to work alongside some of the UK's leading engineers, scientists, and technical specialists on genuinely mission-critical projects.

You'll benefit from:

• A competitive salary and comprehensive benefits package
• The opportunity to work on cutting-edge technologies supporting UK Defence and National Security
• The chance to influence technical strategy and future capability development
• Leadership opportunities within innovative engineering programmes
• Flexible and hybrid working arrangements
• Excellent professional development and career progression opportunities
• A collaborative and supportive working environment
