About Cooled Motors
Cooled Motors is developing next-generation electric drive systems for high-performance automotive and aerospace applications.
We are building advanced propulsion technologies that combine innovations in electric-machine, power electronics, control systems and thermal management to deliver compact, efficient and scalable electric drives for the future of mobility.
Our work sits at the intersection of electric vehicles, aerospace propulsion, advanced manufacturing and clean technology. We are tackling some of the most important challenges in electrification: improving performance, reducing system cost, increasing power density and enabling more sustainable supply chains.
The role
We are looking for a Power Electronics Engineer to help develop the power electronic systems behind our next-generation electric drives.
This is a hands-on engineering role focused on inverter systems, excitation electronics, converter design, sensing, protection, simulation, testing and validation. You will work closely with our electric-machine, control, mechanical and thermal teams to develop integrated drive systems from concept through prototype testing.
The role is primarily focused on power electronics, but a good understanding of motor control, inverter control and electric-machine behaviour will be important.
Key responsibilities
You will:
- Design, model and validate power electronic systems for electric drive applications.
- Develop inverter, converter and excitation power-stage concepts from early architecture through prototype testing.
- Support the design and specification of gate drives, protection circuits, DC-link systems, sensing, filtering and power-stage subsystems.
- Build and use simulation models in MATLAB/Simulink, PLECS, PSIM, LTspice, Simplis, SPICE or equivalent tools.
- Analyse electrical, thermal and dynamic behaviour of power electronic systems.
- Support selection and evaluation of power devices, including silicon, SiC and GaN where appropriate.
- Work with control engineers to ensure the inverter and power electronics meet motor-control and system-level requirements.
- Support PCB schematic review, layout review and design-for-test activities.
- Plan and perform bench testing, inverter testing and motor-drive testing.
- Use lab equipment such as oscilloscopes, power analysers, current probes, high-voltage DC supplies, signal generators and electronic loads.
- Debug hardware faults, switching behaviour, noise issues, protection events and control-interface issues.
- Compare simulation results with experimental data and update models accordingly.
- Produce clear design documentation, test procedures, validation reports and technical reviews.
- Work with suppliers, manufacturers and external engineering partners where required.
Essential requirements
You should have:
- A degree in Electrical Engineering, Electronic Engineering, Power Electronics, Mechatronics or a closely related subject.
- Experience with power electronics, inverters, converters, motor drives or high-voltage electrical systems.
- Understanding of three-phase inverter systems, switching behaviour, PWM, DC-link design, sensing and protection.
- Experience using simulation tools such as MATLAB/Simulink, PLECS, PSIM, LTspice, Simplis, SPICE or equivalent.
- Experience with electric machine control algorithms
- Hands-on experience testing and debugging electrical or electronic hardware.
- Ability to interpret schematics, test data and electrical measurements.
- Understanding of thermal, efficiency and reliability considerations in power electronic systems.
- Ability to work independently in a fast-moving engineering environment.
- Clear technical communication and structured problem-solving ability.
Desirable experience
It would be useful, but not essential, if you have or have experience with:
- Master’s or PhD degree in Electrical Engineering, Electronic Engineering, Power Electronics, Control Engineering, Mechatronics or a closely related subject.
- Electric motor drives or traction inverters.
- SiC or GaN power devices.
- Gate-driver design and protection circuits.
- DC/DC converters, active front ends or high-power converter topologies.
- Motor-control basics, including current control, torque control, PWM and field-oriented control.
- Embedded control interfaces, DSPs or microcontrollers.
- Altium, OrCAD or other schematic/PCB design tools.
- EMC/EMI, filtering, grounding and noise reduction.
- High-voltage safety procedures and test environments.
- CAN, CAN FD, CANalyzer, CANape or similar tools.
- Dynamometer testing or electric motor test rigs.
- Automotive, aerospace, motorsport, EV, industrial drives, defence or electrification programmes.
What we are looking for
We are looking for someone who is practical, analytical and comfortable working close to hardware.
You should be able to move between simulation, design review, lab testing and debugging. You should have a good understanding of how power electronics interact with the motor, controls, sensors, thermal system and mechanical package.
This role would suit someone who wants to take real ownership of power electronics development in a small engineering team, rather than working on a narrow subsystem in a large organisation.
Why join Cooled Motors?
At Cooled Motors, you will have the opportunity to:
- Work on a novel electric traction motor technology.
- Help develop power electronics and controls for a new electric-drive platform.
- Work directly on real prototypes, not just simulations or documentation.
- Gain exposure to electric machines, inverters, embedded control, cooling systems and testing.
- Take real ownership in a small, ambitious engineering team.
- Contribute to technology aimed at reducing rare-earth dependence in electric vehicles and other electrified systems.
- Work with applications across automotive, aerospace, heavy-duty transport, drones and industrial electrification.
Location
Cooled motors has multiple small offices and access to co working spaces in the following locations Sheffield, Coventry, Oxford and London. We operate a hybrid working model and site work when essential.
