HW design engineer - vehicle on-board charger

Opportunities

• The comprehensive product offers a wide range of activities - we offer positions related to the design of power, control and communication circuits
• Large production runs provide the opportunity to develop custom components, use the latest technologies and imply an emphasis on precision development and validation.
• Multinational cooperation with top experts (primarily Germany, additional R&D in US and CN)
• State-of-the-art laboratory
• High dynamics of the electric vehicle sector

Job description:

You will be part of a team that designs the device as a whole (HW, SW, design) and you will be given the space to apply your ideas beyond your duties.

• Identify and implement technical innovations in collaboration with industrial partners, internal experts or scientists
• Calculations and modelling
• Component selection and schematic design
• Analyses, for example related to manufacturing tolerances of components
• Design of prototype DSPs and collaboration with the DSP specialist
• Definition and implementation of associated tests
• Creation of documentation and presentation of results

The position is also suitable for graduates with the aim of gaining expertise in power electronics.

About the product

On-Board Charger (OBC)

Charges the traction battery, but can also turn the vehicle into a large power bank - a bi-directional inverter connected to the 1f/3f grid.

HVLV DC/DC converter

Inverter for powering on-board electronics and battery (e.g. at 12V level) with traction battery potential as input.

Charger Inlet Controller (CIC)

Module for communication between vehicle and stationary charging station

We require:

• Enthusiasm for electronics development and willingness to further your education
