Come and put yourself into a dynamic Principal RF Engineering role at the forefront of real world demands in the defence industry. Alongside ensuring operational excellence for our existing products, there will be the opportunity to develop next generation radar products to counter emerging threats and contribute to our strategy for new technology. Your new day-to-day will be exciting and diverse by applying the principles of RF Engineering across the entire engineering development lifecycle as you join in developing radar systems used by those who serve and protect us.

Who we are:

Join BAE Systems and you’ll be part of something bigger. As a valued member of our global colleague network, you’ll bring your unique skills and perspectives to help pioneer progress and protect what matters most. You’ll be trusted to play your part in delivering the advanced, technology-led defence, aerospace and security solutions of tomorrow, shaping a safer future, for all of us.

From the depths of the ocean, to the far reaches of space, there’s no limit to where a career at BAE Systems could take you.

Role description:

In this role, you will apply deep RF design expertise to develop innovative solutions for both new products and the integration of advanced technologies into legacy systems. You will lead the full design lifecycle, from initial concept through detailed development, verification, and delivery, addressing complex RF engineering challenges with rigour and creativity. Acting as the RF lead at sub‑system and Line Replacement Unit (LRU) level, you will provide authoritative technical guidance, ensure design integrity, and collaborate closely with multidisciplinary teams to meet performance, safety, and compliance requirements.

Core duties:

• Providing technical leadership on RF engineering, guiding design decisions and assuring technical integrity
• Developing, promoting and sharing new RF technologies for adoption across programmes and business areas
• Producing detailed RF system and circuit designs supported by analytical and electromagnetic simulation
• Specifing bespoke procured hardware and verify designs through simulation, analysis, testing and EMC support
• Leading integration activities within complex equipment environments and generate or review technical documentation
• Collaborating with systems, mechanical/thermal, safety, ILS and manufacturing teams; supporting lifecycle reviews, bids and proposals

Essential skills:

• Degree‑qualified in Electronic Engineering (or closely related discipline) with substantial experience in RF technologies, system architectures and circuit design
• Skilled in simulating RF systems using tools such as ADS, HFSS or equivalent modelling environments
• Experienced in producing component‑level designs suitable for volume production, including detailed verification and proving
• Considerable background in integration, defect resolution and gathering evidence to demonstrate acceptance, compliance, safety and fitness for purpose
• Ability to apply rigorous engineering discipline across RF design, simulation, analysis and system‑level validation activities
• Experience in high‑integrity environments and complex radar or sensing systems is adventagous

The Radar Systems Engineering team:

You will be working as a Principal RF Engineer within our close-knit multi-function radar team of inter-disciplinary engineers, evolving our radar portfolio of existing and brand-new radar products to address emerging and future threats.
