This job offering is in the Energy Storage Systems (ESS) group of LGES which develops lithium-ion based energy storage solutions for the stationary market. This market is growing fast due to increasing penetration of intermittent renewable generation resources, the superior performance of ESS compared to conventional gas plants in applications such as frequency response, and falling battery prices. In this rapidly growing market, LGES has a leading position due to its advanced technology, superior product offerings, and strong financial and commercial strength. LGES offers products for all the different sectors of this market i.e. residential, commercial & industrial, grid-scale, and UPS, and in all scales, namely, kW/kWh to multi-MW/MWh. LGES currently has deployments of over 11 GWh with a diverse and large customer base including project developers, utilities, energy service providers, data center and home owners.


The successful candidate will be the lead engineer from the proposal to the execution phase of energy storage projects. He/she is expected to contribute as an individual contributor on all electrical related topics. For other topics, he/she is expected to work with other team members to ensure successful project completion. Key responsibilities include:

  • Review RFPs and provide the required technical response. This includes determining the optimal battery size using LG’s proprietary tools that account for performance, thermal and aging behavior.
  • Design of electrical systems. This includes design of electrical architectures for custom build enclosures/containers and the overall system design. The work should include ampacity calculations, short circuit calculations, arc flash calculations, etc.
  • Collaborate with other engineers on mechanical and thermal management system design for custom build enclosures/containers. Ensure that these enclosures/containers are maintained at optimal temperature ranges throughout the battery life.
  • Design the communication and control architecture.
  • Identify and work with suppliers such as custom build enclosure/container manufacturers and power electronics companies.
  • Perform design reviews.
