Qualifications

• BS or MS in electrical, mechanical, or software engineering with a specialization in control systems or power systems.
• 2-5 years of relevant work experience.
• Experience designing, implementing, and testing controls and automation algorithms in software.

Responsibilities

• Help integrate inverters, batteries, brake resistors, and generators all on a common DC bus.
• Design, implement, and tune control algorithms that coordinate the DC bus, batteries, and grid tie inverters, in simulation and on hardware.
• Implement algorithms and continuous-integration tests (MIL, SIL, PIL) in C++17.
• Develop automation, diagnostics, and fail-safes for a novel integrated platform.
• Analyze system data and refine control strategies.
• Develop and automate test plans, test cases, and traceability matrices to ensure comprehensive coverage.
• Conduct failure analysis, risk mitigation, and validation to maintain robust control performance.
• Debug sensors, actuators, and subsystems, addressing noise, disturbances, and calibration.
• Support fleet generator operation, manufacturing testing, and reliability efforts.
• Collaborate cross-functionally with power electronics, mechanical, thermal, firmware, and test teams to define requirements, integrate multi-physics systems, implement new software features, and drive validation.
• Start by building simulation tests and supporting hardware validation of new grid tie inverter control algorithms, with a structured pathway toward taking full technical ownership of critical control subsystems.
