<div>This is a senior; hands-on field engineering role focused on the electrical power hardware side of microgrid deployment. You will lead commissioning of paralleling switchgear, protection relays, metering, battery systems, power supplies, and control panels across a variety of sites and system configurations. You will work closely with the Principal Controls Engineer (who owns controls software architecture and integration) and the Senior Applications Engineer (who owns design and electrical studies), but your focus is the site/plant: cable/hardware/configuration/integrated testing. You may need to pull/terminate cables, verify terminating cables, verifying protection schemes, energizing equipment, and troubleshooting systems holistically when things don’t work as designed. With an expectation of 50-75% travel, working remote with a field-based focus.  The ideal candidate has a strong technician and field engineering foundation, understands electrical power systems from first principles, and is comfortable working on energized 480VAC, 125VDC, and 1500VDC equipment. You think in terms of whole systems — not just the component in front of you — and you bring the discipline and safety culture needed for hot work, LOTO, and substation operations. BoxPower’s engineering culture integrates AI tools throughout our workflow for documentation, troubleshooting reference, and analysis. You should be comfortable using AI tools to accelerate field documentation and reporting work.
