​Senior Power Electronics Engineer 

Southampton, Hampshire - Some Hybrid working available

£45-60k + Bonus + Excellent Benefits - 4.5 week 

Bowman develops radical new technologies that support businesses across the world in their journey to Net Zero. Bowman’s eTurbo Systems, powered by its unique TorqIQ® technology, are enabling more efficient and flexible use of today’s fuels while accelerating the transition to tomorrow’s.

The primary purpose of this role is to support and be responsible for the development and validation of electric vehicle power electronics and Industrial power electronics for inverters/converters to electrify turbomachinery for a range of applications. 

You’ll develop circuit schematics, layout to design an efficient and cost-effective power electronics hardware using cutting edge technologies, prepare the test bench, support development and validate prototype/products.


  • Design of electrified vehicle/industrial power electronics, such as drives, grid tied power generation including transistor selection, gate drive design, power supply design, measurements circuits, operating and protection strategies.

  • Be responsible for preparing appropriate test bench and test

  • Support in developing concept, proving key technologies and demonstrating the system functionality.

  • Specification of associated passive components, contactors, cables, connectors and fusing.

  • Design and test adequate thermal management solutions for power electronics systems.

  • Demonstrate designs are robust, cost effective and fit for purpose for a high-volume manufacture environment, through detailed laboratory testing, simulation and analysis

  • Participate in customer assessments, post-test inspection reviews, detailed failure analysis

  • Define and carry out all required bench development/validation testing to ensure achievement of all functional objectives and assure compliance to programme goals.

  • Ensure designs can comply with relevant EMC/EMI standards and modifying the design where needed to ensure this is the case.

  • Work closely with suppliers and manufacturing entities

  • Initiating the production solution and developing suitable documentation prior to handover


  • Degree in Electronic Engineering or other relevant discipline with a demonstrable level of industrial experience.

  • Excellent knowledge of power electronic devices, including silicon based IGBTs and MOSFETs through to emerging SiC / GaN based technologies: gate driver, control architecture and measurement circuits, selection/characterisation of devices for inverter, DC/DC converters and battery charger applications

  • Understanding of device characteristics and issues with switching behaviour in real circuits.

  • Knowledge of automotive standards and regulations for hybrid and full-electric vehicles and their components would be desirable. Or alternatively industrial standards for drives and grid tied invertors.

  • DVP&R and DFMEA creation and execution experience, with exposure to ISO26262.

  • Power electronics layout for best compromise between good switching performance, cooling, cost and size.

  • Schematic capture using Altium Designer.

  • Use of SPICE based simulation tools and System level modelling tools such as Matlab, Simulink or

  • Good quality engineering process understanding and appreciation

This company would suit an Engineer who likes variety in their work and the ability to take ownership of power electronics design for a specific project. You'll be working in the 50-100kw range so ideally anything above 10kw is what we are looking for. It’s a small but professional business where intellectual horsepower is readily found. If you like complex and technically challenging problems then this is the place for you.
