Company

hirify.global is developing an autonomous, zero-emissions heavy-duty hauler using vision-based AI for the global logistics network.

What you will do

• Own end-to-end development of the electric powertrain, including the battery pack, high-voltage distribution, motors, inverters, and drivetrain.
• Define system architecture and trade-offs across performance, range, efficiency, thermal management, and durability.
• Lead battery integration, including pack requirements, thermal strategy, high-voltage safety, and BMS interfaces.
• Model energy consumption, thermal behavior, duty cycles, and degradation at the system level.
• Plan and execute component, battery, vehicle, and durability validation, including prototype builds and hands-on debugging.
• Manage supplier technical relationships, review designs, set engineering standards, and mitigate risks related to safety, thermal limits, and reliability.

Requirements

• Bachelor’s degree in Mechanical Engineering, Electrical Engineering, or a related field.
• 5+ years of experience in electric powertrain, battery systems, or vehicle propulsion.
• Strong fundamentals in electric machines, power electronics, and lithium-ion battery systems.
• Experience with high-voltage system design and safety, system modeling tools, and hardware development from concept through validation.
• Hands-on experience prototyping, testing, and debugging electromechanical systems.
• Ability to work independently, make engineering decisions under uncertainty, and collaborate across controls, autonomy, electrical, and thermal teams.

Nice to have

• Experience with heavy-duty trucks, commercial EV platforms, battery pack design, BMS, high-voltage distribution, or thermal management.
• Experience with inverter and motor integration, controls, and scaling systems from prototype to production.
• Familiarity with ISO 26262, SAE, FMVSS, or other automotive standards.
• Experience in fast-paced startup or product development environments.

Culture & Benefits

• Work in a fast-moving, close-knit team of autonomous vehicle industry veterans and innovative engineers.
• Build safety-critical hardware for autonomous, zero-emissions freight transportation.
• Artificial Intelligence tools may assist with comparing qualifications during interviews; a human reviews all output and makes the final decision.
