About the job

Are you looking for an exciting new career opportunity?

Reporting to the Chief Commercial Officer, the Battery Energy Storage System (BESS) Application Engineer is responsible for conducting techno-economic modelling of various use cases and customer installations globally. Models will consider the load and generation profiles, electricity and capital equipment and related installation costs of the entire system at candidate sites. The Application Engineer is expected to be the voice of the customer on technical matters to the CCO and play a critical role in leading business-critical projects.

Position scope and responsibilities

The successful candidate is fluent in all technical aspects of battery sizing and power flows in and out of the battery and is a valued technical resource to advise on product specifications and work packages. You will also be responsible for the following:

  • Analyze various end-use (loads and generation at customers’ projects both utility-scale and BTM) to develop power and energy models to size BESS systems and predict energy throughput through the BESS.
  • Develop techno-economic models that comprehend energy input costs, charge and discharge times, efficiency losses, storage times and resulting revenue.
  • Model Active/Reactive Power, voltage and frequency deviation resulting from varying load, generation and battery manoeuvring.
  • Evaluate costs, system architectures, BOP, and operational requirements for various customer use cases.
  • Research and recommend AC equipment, software and partners for various field installations.
  • Support engineering cost estimations and total cost of ownership of the system to the customer.
  • Monitor and report on the performance of the company’s field pilot installations. Make recommendations for altered charge control and dispatch strategies and other improvements to the design of future systems.
  • Work with the BMS firmware team to develop controls that enable controls that follow optimal charge control/dispatch strategy.
