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.

Desirable Experience

Experience in one or more of the following would be highly advantageous:

• Aerospace or defence
• Automotive electrification
• High-reliability engineering environments
• EMC / EMI
• Understanding how electric machine design affects system-level EMC performance.
• EMC coupling paths, shielding, grounding and filtering.
• Interaction between electric machines and inverter design.
• NVH and thermal systems.
• Advanced engineering materials.
• Design for manufacture and production processes.
• Digital engineering, scripting or AI-assisted engineering workflows.

AI & Digital Engineering

You’ll be encouraged to use AI and digital engineering tools to improve productivity, decision-making, engineering quality and cost efficiency.

You should be able to identify valuable AI use cases while critically assessing and validating 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 move 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.
