Sr. Grid Integration Engineer

About the role

1st Avenue Power is seeking a Sr. Grid Integration Engineer for its System Engineering team in Mountain View/San Jose Bay Area. The role focuses on architecting the software and control fabric that brings power conversion hardware, energy storage, and balance-of-plant equipment together as a dispatchable power plant.

You will build the Energy Management System (EMS) and Power Plant Controller (PPC) layer above PCS, MPPTs, batteries, meters, and switchgear, defining device communications, setpoint flow, and plant behavior under grid operating conditions.

Responsibilities

• Architect and build EMS and PPC software to orchestrate inverters, MPPTs, battery systems, meters, and balance-of-plant equipment as a grid-interactive plant.
• Own the plant Concept of Operations, including sequence diagrams, state machines, and control narratives for PV-only operation, charging, discharging, curtailment, frequency response, voltage regulation, black start, night-mode transitions, and fault ride-through.
• Integrate power electronics, revenue and protection-class meters, balance-of-plant equipment, and PV systems using DNP3, IEC 61850 (MMS, GOOSE, Sampled Values), Modbus TCP/RTU, SunSpec Modbus, MESA-ESS, IEEE 2030.5 (CSIP), OPC UA, and CAN.
• Develop plant-level control logic for active power dispatch, reactive power and voltage support, ramp-rate control, frequency response (PFR / AGC), autonomous curtailment, and setpoint coordination.
• Implement and tune plant-level grid-following and grid-forming control strategies, coordinating inverter modes and virtual inertia.

Key facts

• The role is with 1st Avenue Power's System Engineering team.
• The listed location is Mountain View, United States.
• The role focuses on EMS and PPC software for a grid-interactive power plant.
