Job Title: Prototype Engineering Technician

Job Description

The Prototype Engineering Technician plays a key role in building and supporting next-generation zero-emission refrigerated trailer systems in a hands-on R&D environment. This position focuses on mechanical assembly, system integration, and high-voltage electrical troubleshooting to help bring innovative, sustainable transport refrigeration technology from concept to reality.

Responsibilities

• Lead the mechanical build and assembly of prototype TRU Power 6000 units, supporting a ramp-up to a high volume of builds by year-end.
• Perform high-voltage system integration and troubleshooting, including wiring, harnessing, and electrical diagnostics on prototype and pre-production systems.
• Read and interpret CANalyzer data, fault codes, and system telemetry to identify issues and support system optimization.
• Collaborate closely with engineering teams on prototype builds, design iterations, and system validation activities.
• Build and modify custom wire harnesses and electrical systems to support evolving prototype requirements.
• Support system testing, validation, and root-cause analysis across mechanical and electrical components.
• Create and refine assembly instructions, work instructions, and build documentation to improve repeatability and quality.
• Assist with pre-production builds, commissioning, and field evaluation of refrigerated trailer systems.
• Support material movement, kitting, and build preparation in a prototype shop environment.
• Assist with shipping and logistics for prototype and production units as needed.
• Travel occasionally (approximately 5%) to support on-site installations, commissioning, and field service activities.
• Contribute across functions in a small, fast-paced team environment, taking on varied tasks to support builds, logistics, and field work.

Essential Skills

• Hands-on mechanical build experience, including assembly of complex systems, prototypes, or equipment.
• Exposure to high-voltage electrical systems such as battery systems and HV wiring, with strong safety awareness and diagnostic capability.
• Electrical troubleshooting skills using test equipment such as multimeters, including wiring inspection and fault isolation.
• Experience with mechanical assembly tools and techniques in an R&D or production environment.
• Ability to work effectively with engineering and technical teams to support prototype builds and system integration.
• Strong problem-solving skills applied to mechanical and electrical issues during build and test activities.

Additional Skills & Qualifications

• Experience with wire harnessing and system integration, including building, modifying, and routing harnesses.
• Ability to read and interpret electrical schematics and mechanical drawings.
• Experience using CAN tools and diagnostics, with CANalyzer or similar tools strongly preferred.
• Prototyping mindset, including comfort working in an R&D environment, iterating builds, and adapting to changing designs.
• Strong mechanical aptitude, including use of tools, basic fabrication, and assembly/disassembly of components.
• Experience performing root-cause analysis and structured problem-solving in build and test environments.
• Comfort working in a startup-style environment, wearing multiple hats and supporting builds, logistics, and occasional field work.
• In engineering, electronics, or related technical fields, including familiarity with test equipment and blueprints.
• Skills in electrical and electronics assembly, wiring, troubleshooting, and soldering.
