System Integration Manager

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.

• 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 61850, Modbus TCP/RTU, SunSpec, MESA-ESS, IEEE 2030.5, OPC UA, CAN — including hands-on protocol mapping, point list design, and debugging (Wireshark, protocol analyzers, simulators).
• Hands-on experience with SEL RTAC , Codesys , and MATLAB / Simulink for model-based control development. Experience with industrial HMIs and historians (Ignition, AVEVA/Wonderware, Canary, OSIsoft PI) is a strong plus.
• Strong understanding of grid-following and grid-forming inverter control , droop response, virtual inertia, and the trade-offs between them at plant scale.
• Familiarity with IEEE 1547-2018, IEEE 2800, UL 1741 SB/SC, IEEE 519 , FERC Order 2023, and applicable NERC reliability standards.
• Proven ability to author concept of operations documents, sequence diagrams, state machines, and control narratives that engineering, operations, and external stakeholders can all build against.
• Proficiency in Python (or similar) for tooling, point list automation, and SCADA data analysis.
• Fluency with AI-assisted development — daily use of LLM coding assistants and agentic workflows to accelerate control code, test harnesses, point list generation, protocol parsing, and documentation. Working knowledge of applying ML/AI to operational data (forecasting, anomaly detection, optimization) is a strong plus.
• Strong understanding of LV/MV power plant architecture — transformers, switchgear, BOP, metering, and protection coordination at the plant level.
• Experience supporting commissioning, FAT/SAT, and grid-code witness testing in the field.
• Exceptional communication skills with the ability to translate between control engineers, power engineers, software developers, and utility/ISO counterparts.
• Self-driven, with the grit to solve ambiguous, cross-disciplinary plant-level problems in a fast-paced, clean-slate environment.
• Hands-on experience with the complete lifecycle of utility-scale renewable energy power plant development.
• Experience with industrial communication protocols such as Modbus TCP, CAN, and Ethernet.
• Proven ability to perform failure analysis (FMEA) at both system and subsystem levels.
