• What you will be doing
• When you join as a Radio Frequency Engineer – Aerothermal, you’ll play a pivotal role in shaping the future of advanced defence capability through the Global Combat Air Programme (GCAP).

This highly specialised role focuses on computational analysis, aerothermal performance and electromagnetic design, making it critical to the success of next-generation propulsion systems. It’s an opportunity to apply deep technical expertise, collaborate across multiple disciplines, and contribute directly to one of the most advanced programmes in aerospace engineering.

• Responsibilities
• You’ll be working at the forefront of propulsion technology, applying your expertise in RF engineering to deliver solutions across the lifecycle:

• •Defining RF requirements for adjacent functional disciplines and ensuring they are translated into relatable design constraints.
• •Developing and evaluating powerplant geometric and material concepts that meet RF requirements using appropriate analytical methods.
• •Collaborating across disciplines to mitigate technical development risks and deliver optimised solutions.
• •Performing electromagnetic analyses of components, sub-systems, systems and platform-level integration using industry-standard tools.
• •Specifying and supporting verification and validation activities, including test, measurement, calibration of models and uncertainty quantification.

• Why Rolls-Royce?
• This role sits within our Defence business, in the Global Mechanical Systems Capability, where we deliver cutting-edge propulsion technology and systems integration for programmes of national importance.

To be successful in this role you will need to:

• •Hold a Bachelor’s or Master’s degree in Physics or Engineering (or regional equivalent), or demonstrate equivalent experience.
• •Bring strong technical knowledge in electromagnetic analysis and design methodologies, with awareness of cross-discipline concepts such as manufacturing engineering, aerodynamics, thermodynamics, mechanical/thermal analysis, cost engineering and product definition.
• •Have experience using commercial Computational Electromagnetics (CEM) tools such as FEKO, CST or HFSS, with a good understanding of the strengths and limitations of different analysis fidelities.
• •Apply logical, analytical and innovative thinking to solve complex technical problems and make balanced decisions across both technical and business considerations.
• •Communicate effectively, with the ability to present complex information clearly and confidently to stakeholders at all levels.
