Heavy Duty Truck / Trailer Mechanic

Range Energy•Mountain View, CA

1d•$50 - $75

About The Position

Range Energy builds powered trailers that help electrify heavy-duty trucking without requiring fleets to replace their tractors. We solve real-world problems with real hardware. We move fast, take ownership, and hold a high bar for execution. We value people who are low ego and team-first, calm under pressure, direct and respectful communicators, willing to roll up their sleeves, and focused on solutions, not drama. We operate with high integrity. We do what we say weâll do, weâre transparent about risks and tradeoffs, and we build trust through consistent follow-through. The work is hands-on. Sometimes messy. Often fast. Always meaningful. Founded in 2021, Range is led by experienced EV operators from Tesla, Zoox, Honda, and other leading OEMs. We are backed by strong investors and focused on building hardware that fleets will actually use. If you like building real things, solving hard problems, and working with low drama, high output teammates, you will fit here. Role Summary We are hiring an experienced, hands-on technician to support prototype builds, testing, and early field deployments of Range-powered trailers. This role is primarily focused on high-quality mechanical and electrical execution, structured troubleshooting, and supporting engineering validation efforts. Success in this role requires strong mechanical fundamentals, structured troubleshooting habits, and a willingness to work closely with engineering in a fast-moving environment.
