Firmware & Embedded Software Engineer

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 Firmware & Embedded Software Engineer to own software development across the embedded systems in our trailer platform. This is an early-career role built for engineers who are sharp, hungry, and ready to take real ownership from day one — not someone looking to sit in a support lane.

You'll work across embedded microcontrollers and Linux-based platforms, building the firmware, user-facing interactive features, and diagnostic tooling that our fleet customers interact with directly. You'll collaborate closely with hardware, systems, and validation engineers to bring up new features, debug complex integration issues, and help establish the development and release practices that the team depends on. If you move fast, learn faster, and want your code running on real trailers on real roads, this is the role.

• Develop and ship firmware on embedded microcontrollers (e.g. STM32) — interrupt handling, peripheral drivers, communication protocols, feature logic, and the user-facing UI and display functionality that operators interact with directly
• Develop and maintain software on embedded Linux platforms for system configuration, diagnostics, and integration
• Own development of desktop applications that interface with trailer systems — enabling field teams and customers to configure, inspect, and maintain the platform
• Build and maintain diagnostic and maintenance tooling: workflows, procedures, and code that field teams and customers use to inspect, configure, and troubleshoot the system
• Integrate and debug firmware across CAN-based vehicle networks, validating correct behavior at the system and subsystem level
• Collaborate with hardware engineers on bring-up, signal-level debugging, and schematic review to close the gap between hardware and software
• Write test cases and support SIL/HIL validation pipelines; contribute to automated test coverage for firmware features
• Participate in code reviews, contribute to coding standards, and help build a culture of quality on a fast-moving team

• Deliver multiple customer-facing UI features end-to-end — from implementation on-device through integration and validation — within the first 6 months
• Own and ship a meaningful piece of diagnostic or maintenance tooling that field teams rely on
• Demonstrate the ability to independently debug complex firmware issues across hardware and software boundaries with minimal hand-holding

Range Energy's compensation package includes a competitive salary, equity for all full-time roles, and a generous benefits package. The salary range for Mountain View, CA based applicants is between $140,000 - $180,000 annually. The total compensation will be determined based on multiple factors including domain knowledge, experience and location.
