Firmware Validation 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.

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. Additionally, you will work with our various suppliers to ensure proper integration and functionality of their software within our trailer platform, and serve as a primary internal contact for addressing, debugging, and resolving firmware issues in pilot and production assets.

We are looking for individuals who are passionate about software, automation, and building robust, scalable solutions. This role requires a high degree of autonomy. Success in this role depends on comfort making recommendations to the wider organization and proactively shaping validation processes, starting from the ground level.

Range Energy values applicants of all different backgrounds, experiences, and skill sets. If you think you could excel in this role (regardless if you meet all the qualifications), we encourage you to apply.

Inside the Role (Responsibilities)

• Develop and build upon validation procedures, automated testing, and release acceptance criteria for all firmware and software components of our eTrailer system.
• Collaborate with hardware, systems, and embedded software engineers
• Implement, test, and document automated testing infrastructure
• Write testing and release procedures for the eTrailer system
• Support hardware/software feature testing, participate in code reviews, contribute to developing best practices for software development at Range Energy
• Be hands-on with ECUs and wiring harnesses, testing features and diagnosing issues from the test bench to full trailer systems
• Serve as the first point of contact for firmware-related field issues reported by our field application engineers, including log collection, issue reproduction, and root-cause narrowing before escalation

The Must Haves (Qualifications)

• Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Computer Science, or related field.
• 2-8+ years of engineering experience (can include collegiate student teams)
• Experience developing and debugging applications on embedded devices
• Experience in programming with C/C++ and Python
• Experience with version control systems like Git
• Competency with electrical engineering fundamentals and hardware troubleshooting
• Comfortable using AI-assisted development tools while maintaining strong, independent technical judgment
• Desire to learn, solve difficult problems with imaginative solutions, and own complex systems
• Ability to work independently with minimal guidance or requirements definition, and be flexible to constantly changing company needs

Bonus Points (Preferred Skills)

• Experience with developing test automation infrastructure and writing test cases (software- and hardware-in-the-loop, pytest, etc.)
• Experience with CAN bus and automotive control architecture
• Familiarity working and developing in a Linux environment
• Experience with UDS
• Familiarity with EV charging standards and protocols
• Comfortable with electrical diagnostic and lab equipment (multimeter, oscilloscope, power supplies)

Other Requirements

• Physical Requirements: Ability to lift and carry up to 40 pounds of equipment. Comfortable with occasional bending, kneeling, and climbing as required for infrastructure maintenance.
• Travel Requirements: Some travel may be required for customer, pilot, and manufacturing support
• While we appreciate the importance of schedule flexibility, it's essential to note that the nature of this role necessitates a regular and consistent onsite presence.

What Success Looks Like (first 6-9 months)

• In your first 6-9 months, success would include establishing a repeatable firmware release validation process, building automated test coverage across core ECUs, and significantly reducing ad-hoc field debugging escalations. This role has a clear growth path into technical leadership in validation, systems, or firmware quality ownership as the team scales.
