Principal Electromagnetic Engineer (EMAG / EMC Focus)

Principal Electromagnetic Engineer – EMAG / EMC<br />Location: Sunbury-on-Thames, Surrey<br />Shape the Next Generation of Electric Machines<br />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.<br />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.<br />You’ll work from early concept and customer requirements through to design, validation and production release, solving complex engineering challenges along the way.<br />The Role<br />You’ll become a key technical authority for electromagnetic design across multiple development programmes, working closely with engineering, manufacturing and prototype teams.<br />Your expertise will help shape high-performance electric machines for demanding, high-reliability applications.<br />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.<br />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.<br />Desirable Experience<br />Experience in aerospace, defence, automotive electrification or other high-reliability engineering environments would be advantageous.<br />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.<br />AI &amp; Digital Engineering<br />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.<br />Why This Role?<br />This is more than a simulation role.<br />You’ll have the opportunity to take ownership of complex electromagnetic engineering challenges and see your designs progress from concept → simulation → prototype → validation → production.<br />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.<br />Ready to engineer what comes next?
