The Job

Reporting to the Chief Engineer of Electrical Systems, this client seeks a Power Electronics Engineer with experience of developing e-machine/motor control power electronics for production; particularly for automotive traction applications in EV and hybrid vehicles at system power levels from 50kW to >750kW.

The UK Electrical department is currently involved in the customer-facing delivery of both hybrid and pure electric drivetrain solutions, supported by a team of over 110 e-machine; power electronics; electronic hardware and software specialists based in Würzburg and Lenting, Germany.

The key functions of the role:

Lead the design and delivery of motor control power electronics for a variety of customer applications, interfacing directly with the design teams in the UK and Germany and/or the appropriate project team.

Capture and manage inverter hardware requirements, developing into specifications; schematics; PCB layouts and drawings, ensuring alignment between internal team(s), suppliers and the customer.

Design and develop inverter hardware, including gate drivers; control boards; DC link components and selection and characterisation of power modules. Use intelligent design to deliver modular and scalable solutions; often based on internal inverter platform development.

Management and definition of inverter mechanical interfaces and requirements, to include thermal system.

Develop customer inverter components to the agreed requirements and processes, from concept level through to production.

Contribute to system and lead inverter-level safety case development, and follow industry standard techniques to ensure a robust design, e.g. FMEA.

Plan and action Design Verification (DV) and Production Validation (PV) activity at a component level.

Manage interfaces between the inverter and the rest of the e-powertrain system, liaising with cross-functional teams within hofer and the customer.

Liaison with, including travel to, other hofer sites in order to co-ordinate design activities and ensure delivery is in line with the programme requirements.

Qualifications / Education / Experience required:

Degree or equivalent in a relevant Engineering or Science related discipline.

Demonstrable power electronics design experience in an automotive or similar engineering environment.

Proven experience of developing inverters for production applications and understanding their interfaces and integration into the powertrain system(s) and vehicle.

Verifiable experience in inverter Specification; Requirements Capture/Management and DV and PV processes.

Strong background and knowledge of power electronics, analogue and digital circuits and schematic capture and development. Highly familiar with IGBT and future power switching technologies.

Good understanding of automotive HV standards; design methodologies and working practices.

Experience of designing power electronics in accordance with ISO26262 Functional Safety processes and concepts, and an understanding of what this means for hardware design processes and the design realisation.

Solid understanding of asynchronous and synchronous motor control theory, and motor position sensing technologies.

Confident user of MS Office products and competent user of industry-standard network and calibration tools, e.g. Vector CANalyzer, Vector CANape, ETAS INCA.

Experienced user of electronic CAD packages (e.g. Altium designer) and simulation packages (e.g. PSpice, LTspice).

Other beneficial attributes:

An understanding of the implementation of automotive-qualified microcontrollers, specific experience with the Infineon Aurix family would be advantageous.

Personal attributes:

Excellent attention to detail with good planning skills.

Strong communicator, capable of interacting with cross-functional teams both internally and externally.

Highly self-motivated and independent, with a willingness to seek guidance and involve others whenever required.

Remain focussed under pressure, familiar with working outside their normal comfort zone.

Proven record of operating in a customer-facing environment.
