EV.Careers is seeking a full-time, direct-hire Operations & Service Technician for one of our partners: a Chelmsford, Massachusetts manufacturer of modular, battery-agnostic energy storage systems for commercial, industrial, and residential customers. In this hands-on role you will own the full technical lifecycle of the companyâs deployed Mobile Power Station hardware â from acceptance testing and in-house repair to field troubleshooting, failure analysis, and structured feedback to the engineering team.
This is a builderâs seat at a small, founder-led company. You will split your time roughly evenly between hands-on technical operations at the Chelmsford facility and on-site service travel to customer locations. You will partner directly with Engineering to investigate failures, validate hardware improvements, and evaluate prototype units, while making sure equipment is properly prepared, tested, and ready to deploy. The role also carries limited warehouse operations, inventory management, and shipping, so you will have real ownership over how the service and operations function runs and matures.
