  • safety-critical builds.
  • Develop infrastructure to run automated test suites including regression, simulation,
  • and hardware-in-the-loop.
  • Energy Storage Integration
  • Apply knowledge of utility-scale energy storage systems (battery management, PCS
  • interfaces, dispatch logic).
  • Participate in the development of control panel design for various components of energy
  • storage system.
  • Design & develop EMS/SCADA application to map controls data into historians, HMIs,
  • and cloud telemetry systems for monitoring & management of the system.
  • Support system integration, commissioning, and field validation.

Requirements
