Mechanical Engineer II / Staff

About Range Energy 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 we’ll do, we’re 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're looking for a Mechanical Engineer with high drive, low ego, and a genuine desire to own hard problems across our trailer platform. This role sits at the center of our hardware development process — you'll be hands-on with CAE, executing FEA models and validating designs through simulation, while also contributing directly to the physical design and integration of trailer subsystems. The level is open. Whether you're early in your career and ready to build real skills fast, or an experienced engineer looking to take on significant technical ownership with minimal hand-holding, we want to talk. What matters is strong fundamentals, a bias toward execution, and genuine curiosity about how things work. You'll partner closely with systems, electrical, and manufacturing teams to ensure designs are robust, manufacturable, and ready for the road.
