System Integration Manager

Location: Mountain View/San Jose Bay Area
Team: System Engineering

The Impact You’ll Make

The System Integration Manager owns the end-to-end integration of power electronics subsystems — inverters, DC/DC converters, battery management systems, controllers, and protection equipment — into complete, field-ready renewable energy systems. This role sits at the intersection of electrical, hardware, controls, mechanical, and software engineering, translating subsystem-level designs into a system that works reliably together, passes certification, and performs in the field. The ideal candidate has hands-on experience bringing power electronics hardware through system-level validation, and is comfortable being the person who catches integration problems before they become field failures.

Key Responsibilities

System Architecture & Integration

• Own the system-level integration across power electronics, battery, controls, and mechanical/thermal subsystems for BESS and PV/hybrid products.
• Define interface control documents between subsystem teams — electrical interconnects, communication protocols (CAN, Modbus, RS-485), control signal timing, and grounding/bonding schemes.
• Identify and resolve cross-domain design conflicts (e.g., thermal derating impacts on power electronics placement, EMI/EMC interactions between converters and BMS communication).
• Lead root-cause investigations when subsystems that pass individual qualification fail at system level.

Verification & Validation

• Develop and execute system-level test plans: power-up sequencing, fault injection, grid-fault ride-through, protection coordination, and communication/control loop validation.
• Coordinate factory acceptance testing (FAT) and site acceptance testing (SAT) for containerized BESS and PV systems.
• Work with the safety/certification team to ensure system designs support UL 9540, UL 9540A, UL 1741, and UL 1973 pathways, and that integration choices don't compromise certification scope.
• Maintain traceability between requirements, interface specs, and test evidence for design reviews and customer/lender due diligence.

Cross-Functional Leadership

• Act as the technical integration point of contact across mechanical/thermal, electrical/power electronics, BMS/firmware, and safety/certification teams.
• Support new product introduction (NPI) by flagging integration risk early in the design cycle, not just at system test.
• Mentor integration engineers and test technicians; build out test infrastructure and documentation standards as the team scales.

The Skills You Bring

• Degree in Electrical Engineering, Controls, or equivalent experience with a focus on Power Systems, Control Theory, and software-defined controls.
• 5+ years of experience building EMS, PPC, or plant-level controls for utility-scale solar, storage, hybrid, or wind power plants.
• Deep working knowledge of utility and industrial communication protocols: DNP3, IEC
