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.

Contribute to system architecture decisions and technical strategy
Write clean, maintainable, and well-tested code in a fast-paced environment

What Success Looks Like (first 6–12 months)

Establish and manage a configuration database for tracking and servicing deployed production units.
Build and deploy scalable infrastructure for long-term data storage and tracking from deployed systems.
Develop end-to-end (frontend and backend) testing infrastructure for factory and commissioning data.
Create comprehensive tooling (frontend and backend) to support field service operations and diagnostics.
For the above projects, some of these may involve evaluating 3rd party software tools and integrating them with internal tools that you are responsible for developing

Required Qualifications

3–7+ years of experience in full stack software development
Strong proficiency in modern frontend frameworks (e.g., React, Vue, or similar)
Backend experience with languages such as Python, Node.js, or Go
Experience building and consuming RESTful APIs and working with distributed systems
Familiarity with cloud infrastructure (AWS, GCP, or Azure)
Experience with databases (SQL and/or NoSQL), and with time-series high-resolution, high-volume data
Strong understanding of software engineering best practices (testing, version control, CI/CD), as well as familiarity with building and maintaining CI/CD pipelines
Ability to work cross-functionally with hardware and embedded systems teams

Preferred / Nice-to-Haves

Experience working with IoT systems, telemetry data, or connected devices
Familiarity with vehicle data protocols (CAN, UDS, etc.)
Experience building data visualization tools or analytics platforms
Exposure to real-time data processing (Kafka, streaming systems, etc.)
Background in fleet, logistics, automotive, or energy industries

About the company

Range Energy designs and builds powered and intelligent trailers that attach to standard tractors to cut fuel use and emissions in heavy-duty trucking. Its flagship RA-01 is a 53-foot electric trailer with an e-axle and a 200 or 300 kWh battery that measures hitch force and adds propulsion through its own axle, letting the tractor behave like it’s pulling an empty trailer. The system can power auxiliary loads (like refrigeration) and works with Thermo King, while a telematics platform provides fleet insights on emissions, routes, and maintenance. Unlike rivals, Range Energy offers a retrofit solution with direct sales (and potential leasing/service) to large fleets, focusing on immediate decarbonization without replacing tractors to speed up electrification.

Simplify's Take

What believers are saying

MVTS reported 36.9% fuel efficiency gains from Range's trailer testing.
Dot Transportation planned a 2025 pilot across its 2,600-trailer fleet.
ZF partnership and South Coast AQMD collaboration validate market interest and regulatory relevance.

What critics are saying

Commercialization depends on pilots turning into purchases before 2026 production starts.
Range raised only $23.5 million in February 2024, limiting manufacturing runway.
Trailer batteries, e-axles, and service networks create existential execution risk if reliability slips.

What makes Range Energy unique

Range's powered trailers retrofit existing diesel fleets without tractor replacement.
Thermo King and ESL Power Systems extend Range into refrigerated freight in 2025.
Fei Liu joined in March 2026 to scale hardware manufacturing and operations.

Range Energy Debuts Its Next Generation Electric-Powered Trailer System, The Rb-01, At The Advanced Clean Transportation Expo

LAS VEGAS--(BUSINESS WIRE)--Range Energy (Range), the company bringing powered trailers to the commercial trucking market, today debuted its next generation electric-powered trailer system, the RB-01, at the Advanced Clean Transportation (ACT) Expo. The RB-01 is the next iteration in Range’s series of trailer systems with initial tests yielding 47-67 percent miles-per-gallon (mpg) improvements, equivalent to a 32-40 percent reduction in fuel costs. Notably, during its transit to ACT, the tractor towing the RB-01 achieved 18.1 mpg during the final 281.6 miles between Bakersfield, CA and Las Vegas, NV. The results from this trip included a 2,000-foot net elevation gain and 12,000 feet total of climbing with ambient temperatures as high as 105 degrees Fahrenheit. The electric-powered trailer system includes an e-axle, 200 or 300 kWh battery pack, and smart kingpin, and is built with hardware and software components that are sourced from Range’s supply chain partners. Improved results shown by the RB-01 highlight Range’s continued progression of its trailer system to ease the transition to electric for fleet owners and operators, and in doing so, significantly reduces emissions and improves the efficiency of fleets’ diesel-powered heavy-duty trucks in the near-term
