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.

 

Position Snapshot

Range Energy is looking for a Firmware Validation Engineer. As a Firmware Validation Engineer at Range, you will be responsible for testing and releasing firmware for our eTrailer System. Collaborating closely with hardware, systems, and embedded software engineers, you will support the development and integration of automated tests and release processes for our eTrailer System. Your role will involve debugging, testing, and documenting various embedded software features on the electronic control units (ECUs) in our trailer platform. These features are multidisciplinary in nature and sit at the intersection of electrification, functional safety, security, software defined vehicles, and energy management.
