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.
