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 electricmotors, 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, work packages and development programmes from concept through to production. Consider electromagnetic, thermal, mechanical and system-level integration throughout the design process. Lead or make significant contributions to DFMEA, technical risk assessment and design robustness. Provide hands-on technical support during prototype builds and manufacturing activities. Work directly with prototype hardware, including windings, laminations and assembly processes. Investigate failures and lead structured root-cause analysis and corrective actions. Support electrical, mechanical and thermal validation and qualification testing. Prepare high-quality engineering reports, technical documentation, test plans and design review material. Produce and review 2D/3D CAD, drawings and BOMs where required. Support verification and validation activities and provide evidence for formal design reviews. Act as a technical reviewer, authority and mentor within the engineering team. Support concessions, deviations and non-conformance investigations where required.

What You’ll Bring

Essential:

Bachelor’s or Master’s degree in Electrical Engineering or a related discipline. Significant experience in electric machine electromagnetic design. Experience with machine technologies such as PMM, BLDC, BLAC, RFM or AFM. Strong understanding of: Electromagnetic theory Machine topology selection Magnetic materials Loss mechanisms EM/thermal coupling Mechanical and structural considerations Strong working knowledge of ANSYS Motor-CAD and ANSYS Maxwell. Experience acting as a technical authority, reviewer or approver. Strong experience with DFMEA and technical risk management. Experience in failure analysis and structured problem solving. Understanding of concessions, deviations and non-conformance management. A practical, hands-on approach and confidence working directly with prototype and manufacturing teams. Ability to turn complex technical requirements into practical machine-level designs. Excellent communication, documentation and stakeholder-management skills. Strong ownership and accountability for technical decisions. Ability to manage multiple projects and priorities.
