Job Description

Mainspring Energy manufactures and delivers fuel-flexible, low-emissions local power solutions that rapidly add new capacity and deliver reliable, affordable, and sustainable electric power.

Key Responsibilities

Lead the selection, sizing, and configuration of industrial grid-interactive off-the-shelf (OTS) inverters
Lead the troubleshooting and root cause analysis of complex hardware issues arising in the field, lab, or during testing of grid forming and grid following inverters and AC power systems
Configure and tune inverter parameters for stable operation across grid-forming and grid-following modes
Design system-level tests to validate grid-edge behaviors, including low-voltage ride-through (LVRT) and frequency response
Analyze AC power waveforms, power quality, and fault behavior to diagnose system issues
Ensure system compliance with grid interconnection standards such as IEEE 1547, UL 1741, and local utility requirements
Perform critical design reviews and collaborate cross-functionally with mechanical, thermal, controls, test engineering and software engineers to ensure holistic system performance and manufacturability

Requirements

Bachelor's or Master's degree in Electrical Engineering or a related field
3+ years of hands-on experience working with power inverters or power conversion systems
Strong troubleshooting skills with AC power systems, including waveform analysis, fault behavior, and system stability
Comfort working on high voltage systems (400-800 Vac, up to 1500Vdc) in both a laboratory and industrial field environment
Experience with industrial communication protocols (Modbus TCP/RTU, CANbus, SunSpec) for power electronics control
Working knowledge of NEC (NFPA 70), specifically regarding grounding, conductor sizing, and overcurrent protection for power generation systems.
The ability to work independently and own complex technical problems from initial identification through final resolution
