RF Design Engineer

RF Design Engineer

Roke imagines a more secure world. A world where technology protects, rather than exposes. A world where expert engineers, consultants and business support staff collaborate to protect what matters most to our clients. This role combines hands‑on design with project leadership.

Roke is a leader in cutting‑edge technology solutions for the defence industry with clients spanning National Security, Defence, and wider. We work alongside our customers to solve their complex and unique challenges.

As an RF Design Engineer at Roke, you will play a pivotal role in designing and developing cutting‑edge RF electronics for defence and electromagnetic warfare applications. You will have the opportunity to work on challenging projects that make a significant impact on defence and national security.

• Design, simulate, and implement RF and analogue electronic circuits and systems for defence‑related projects (in domains such as electromagnetic warfare, positioning and timing, and survivability) with cutting‑edge solutions.
• Conduct hands‑on integration, testing, troubleshooting, and debugging of RF and analogue electronic circuits, systems and components, to optimise their performance (e.g., impedance, VSWR, wideband operation).
• Participate in design reviews and provide valuable technical input to enhance project outcomes.
• Prepare and maintain technical documentation and reports with highest quality (e.g., design specifications, test plans, and results for compliance evidence) with a focus on RF and analogue electronic circuits and systems.
• Provide technical support to the Technical Lead (e.g., risk management, input to customer meetings).
• Provide mentoring and feedback to junior engineers, in support of the team's professional growth.
• Proactively communicate and collaborate with stakeholders, within and outside the project team.
• Comply with Roke policies effectively.
• Comply with Roke design and development processes.
• Possess excellent problem‑solving and analytical skills.

• Excellent communication and organisation skills.
• Foster the use of industry standards and best practices and safety standards, to ensure compliance, in a collaborative agile delivery.
• Identify and collaborate with all stakeholders.
• Engage with other technical experts.
• Provide guidance to colleagues and stakeholders.
• Able to work independently and as part of a collaborative team.

• Undertake engineering design and development activities on time, on budget and in quality.
• Provide timely and accurate estimates of effort to completion, assessing complexity, and identifying risks.
• Support the definition of, and meeting of, project goals.
• Work closely with Project Managers, Design Authorities, Systems Engineers, and other stakeholders to translate project requirements into actionable tasks.

• Collaborate with cross‑functional teams.
• Foster a positive and productive work environment.
• Identify opportunities for improving engineering processes and practices.
• Implement best practices and tools to enhance efficiency and effectiveness in the development.
• Continually review the process by identifying bottlenecks and proposing improvements.

• Excellent skills in using Microwave Office.
• Excellent skills in using Altium.
• Design at frequencies from LF up to X Band.
• Design of Low Noise Amplifiers.
• Design of receivers.
• Working with high‑power amplifiers.
• Knowledge of the defence business domain.

• Bachelor’s or Master’s degree in Electronics Engineering, or equivalent qualification in the relevant field.
• Experience in development and use of RF performance models (e.g., Microwave Office) and PCB circuit layout design (e.g., Altium).
• Experience in designing solutions with very low SWaP‑C (Size, Weight and Power, and Cost).
• Experience in RF design for harsh environments (EMC, vibration, thermal).
• Experience overseeing the transition of development hardware into production, including environmental testing, qualification testing and design certification.
• Experience working with spectrum analysers,…
