* Specific sites setup to support many of the German OEMs

* Involved in many current and future AT, AMT, DCT and MT volume transmission design projects from clean sheet to production

* Ourc client has its own inverter / electric control technology and has designed hybrid modules and e-motors that are in production across the world

* Full design to production experience of hybrid powertrain technologies from energy storage to the road

* Full engine and motor driven test capability

* Production supplier to VAG group

Reporting to the Chief Engineer of Electrical Systems, Our UK office 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 powertrain 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 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.

* A minimum of 10 years' 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).
