Radio Frequency Engineer

Radio Frequency Engineer – Aerothermal

Full time – Hybrid, Bristol

Job Description

As a Radio Frequency Engineer – Aerothermal at Rolls‑Royce, 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 is critical to the success of next‑generation propulsion systems.

The position focuses on computational analysis, aerothermal performance, and cross‑disciplinary design. If you’re driven by innovation, problem‑solving, and applying deep technical knowledge in aerodynamics, thermodynamics, and computational methods, this is an opportunity to influence one of the most advanced programmes in aerospace engineering.

Why Rolls‑Royce?

Rolls‑Royce is one of the most enduring and iconic brands in the world and has been at the forefront of innovation for over a century. We design, build and service systems that provide critical power to customers where safety and reliability are paramount. This role sits within our Defence business, delivering cutting‑edge propulsion technology and systems integration for programmes of national importance.

What You Will Be Doing

• Define and translate radio frequency (RF) requirements into practical design constraints, ensuring alignment with adjacent functional disciplines and rig test requirements.
• Develop and assess powerplant concepts that meet RF demands, applying advanced analytical methods to support robust, optimised solutions across platform and powerplant levels.
• Collaborate across engineering functions to reduce technical risk, perform electromagnetic analyses, and carry out verification and validation activities to ensure requirements are met.
• Lead the capture, management and communication of RF technical knowledge, including modelling, test data, reporting and evidence cataloguing to maintain technical integrity throughout the lifecycle.

Who We’re Looking For

• 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.

Benefits

We offer excellent development opportunities, a competitive salary, and exceptional benefits. These include bonus, employee support assistance, and employee discounts. Hybrid working is supported so you can balance time between the office, home or another remote location.

Additional Information

We are an equal opportunities employer. We’re committed to developing a diverse workforce and an inclusive working environment. We hold a Security Check clearance; Rolls‑Royce will support the application for Security Clearance if you do not already have this in place. Due to the nature of the work, we only progress applications from individuals who are a UK national or, in MoD approved cases, a dual national.
