Power Electronics Engineer

  • Full-time

Company Description

We are on a mission to help people lower their electricity bills. We want to provide every household and small business with a better way to access cleaner, cheaper energy and help protect the planet. Our smartly designed energy storage systems reimagine how batteries are connected, distributed and used. Flexible and modular, our systems are intelligently managed via the cloud to maximise life make energy storage more affordable for everyone.

Job Description

We are seeking a power electronics specialist to join our team and lead the design of power conversion systems including AC/DC bi-directional converters, DC/DC converters, offline isolated power supplies, and inverters including the selection of topology, semiconductors, magnetics design, schematic design and layout, EMC and design of various safety aspects.

Responsibilities

  • Start-to-finish ownership of the power conversion system from specification through design, prototype, validation and manufacturing
  • Design AC-DC converters by contributing to product level features, design, and vision by leveraging your experience and creativity
  • Writing hardware specifications, selecting components, directly interfacing with external consultants and suppliers
  • Creating all relevant technical and project management documentation (requirements, specifications, DFMEA, test plan, project plans, etc.)
  • Testing of in-house prototypes and external converters to validate functionality, optimise performance, and evaluate critical characteristics
  • Collaborate to create efficient test and validation mechanisms for the individual components as well as the complete system and support of the development of custom test cards
  • Defining, maintaining and enforcing good engineering practices withing Embedded Hardware Development unit in field of EMI/EMC and Grid Compliance
  • Work in a multi-disciplinary research, development, and engineering environment

Qualifications

  • PhD in Electronics Engineering, or equivalent electronics knowledge
  • Minimum 3 years of experience in power electronics
  • Detailed understanding of active and passive component losses in power conversion and the various means to reduce/mitigate those losses
  • Familiarity with various topologies (two-level, multilevel, soft switching, etc.) and ability to analyse, select, and design topologies best suited for a given application
  • Knowledge of sensor design to measure converter parameters in real time in a noisy environment 
  • Familiarity with magnetics design and specification, applications of various core materials for both power and filtering, knowledge of winding structure and optimisation, and insulation strategies
  • EMC design and optimisation applied to PCB layout and filter designs
  • Ability to design schematics and conduct layout design or review as it applies to power conversion
  • Strong lab skills with working knowledge of the tools and techniques for power conversion test and analysis (e.g., use of oscilloscopes, impedance analysers, sources, and loads in an environment with both high voltages and currents, and high common-mode and differential-mode noise)
  • Working with high voltage, current, and power
  • Ability to simulate power converter systems
  • Familiarity with embedded control and application and programming of microcontrollers, PLDs and the like
  • Must be self-motivated and an effective team player
  • Eligible to work in the UK

Nice-to-haves

  • Good knowledge of Lithium-based battery cells and battery systems
  • Experience with battery management systems
  • Previous work in the solar, energy storage, or EV/ EV Charging
