Principal Electromagnetic Engineer (EMAG / EMC Focus)

Principal Electromagnetic Engineer – EMAG / EMC Location: Sunbury-on-Thames, Surrey Shape the Next Generation of Electric Machines We’re looking for a Principal Electromagnetic Engineer to play a leading role in the development of advanced electric motors, generators and electro-mechanical systems. This is a senior technical position for an engineer who combines deep electromagnetic design expertise with a hands-on approach to prototype development, testing and manufacturing. You’ll work from early concept and customer requirements through to design, validation and production release, solving complex engineering challenges along the way.

The Role

You’ll become a key technical authority for electromagnetic design across multiple development programmes, working closely with engineering, manufacturing and prototype teams. Your expertise will help shape high-performance electric machines for demanding, high-reliability applications. What You’ll Do

• Lead electromagnetic design activities across product development programmes.
• Develop and optimise electric machine designs using ANSYS Motor-CAD and ANSYS Maxwell.
• Build analytical and simulation models to assess sizing, performance, losses, efficiency and NVH.
• Translate customer requirements and technical specifications into robust machine architectures and design concepts.
• Support technical proposals and development programmes from concept through to production.
• Consider electromagnetic, thermal, mechanical and system-level integration throughout the design process.
• Lead or contribute to DFMEA, technical risk assessment and design robustness.
• Provide hands-on technical support during prototype builds and manufacturing activities.
• Investigate failures and lead structured root-cause analysis and corrective actions.
• Support electrical, mechanical and thermal validation and qualification testing.
• Prepare engineering reports, technical documentation, test plans and design review material.
• Produce and review 2D/3D CAD, drawings and BOMs where required.
• Act as a technical reviewer, authority and mentor within the engineering team. What You’ll Bring
• Bachelor’s or Master’s degree in Electrical Engineering or a related discipline.
• Significant experience in electric machine electromagnetic design.
• Experience with technologies such as PMM, BLDC, BLAC, RFM or AFM.
• Strong understanding of electromagnetic theory, machine topology, magnetic materials, loss mechanisms and EM/thermal coupling.
• Strong working knowledge of ANSYS Motor-CAD and ANSYS Maxwell.
• Experience acting as a technical authority, reviewer or approver.
• Strong experience with DFMEA, technical risk management and failure analysis.
• Understanding of concessions, deviations and non-conformance management.
• A practical, hands-on approach with confidence working alongside prototype and manufacturing teams.
• Excellent technical communication and documentation skills.
• Strong ownership and accountability for technical decisions.
• Ability to manage multiple projects and priorities. Desirable Experience Experience in aerospace, defence, automotive electrification or other high-reliability engineering environments would be advantageous. Additional experience with EMC/EMI, NVH, thermal systems, advanced materials, design for manufacture, digital engineering, scripting or AI-assisted engineering workflows would also be beneficial. AI & Digital Engineering You’ll be encouraged to use AI and digital engineering tools to improve productivity, decision-making, engineering quality and cost efficiency, while applying sound engineering judgement to validate AI-generated outputs. Why This Role? This is more than a simulation role. You’ll have the opportunity to take ownership of complex electromagnetic engineering challenges and see your designs progress from concept → simulation → prototype → validation → production. If you’re a senior electromagnetic engineer who enjoys both deep technical analysis and hands-on engineering, this is an opportunity to make a real impact on the future of electric machine technology.
