Mechanical Assembly Technician

Parallel Systems is pioneering autonomous battery-electric rail vehicles designed to transform freight transportation by shifting portions of the $900 billion U.S. trucking industry onto rail. Our innovative technology offers cleaner, safer, and more efficient logistics solutions. Join our dynamic team and help shape a smarter, greener future for global freight.

Mechanical Assembly Technician

Parallel Systems is seeking a Mechanical Assembly Technician to support the assembly of our first production autonomous battery-electric rail vehicles. This role will be embedded in the build process from the ground up, working alongside our manufacturing partner and engineering teams to develop a deep understanding of how our vehicles are assembled, identify quality and process issues, and help improve how future vehicles are built.

The ideal candidate is a hands-on technician with experience assembling complex mechanical systems, thrives in low-volume production environments, and is comfortable working directly with engineers to solve problems on the shop floor.

This position is based at our Los Angeles facility and requires extensive travel to our contract manufacturer during active vehicle builds.

Responsibilities:

Support the end-to-end mechanical assembly of Parallel’s first production vehicles at our contract manufacturer’s facility

Perform hands-on assembly using hand tools, power tools, torque tools, fixtures, and shop equipment

Read and follow mechanical drawings, work instructions, torque specifications, and build documentation

Develop a comprehensive understanding of the vehicle architecture, subsystems, and assembly sequence

Identify quality issues, assembly challenges, and opportunities to improve vehicle design and manufacturing processes

Work directly with design and manufacturing engineers to communicate issues and implement corrective actions

Document lessons learned, assembly procedures, quality checkpoints, and recommended process improvements

Support the fabrication and assembly of engineering test benches, fixtures, prototype hardware, and other equipment at Parallel’s Los Angeles shop

Help develop standardized work instructions and processes for future vehicle builds

Train and support additional technicians as Parallel’s manufacturing team grows

What Success Looks Like:

After 30 Days: You’ve developed a strong understanding of the vehicle architecture, assembly documentation, and manufacturing process and are actively supporting production builds

After 60 Days: You’re independently completing major assembly tasks, identifying issues before they slow production, and working directly with engineering to improve build quality and repeatability

After 90 Days: You’ve helped bring the first three production vehicles to completion and are providing specific, actionable feedback on engineering and assembly process improvements

After 180 Days: You’ve supported the completion of the full initial production run, developed a comprehensive understanding of the end-to-end build process, and are helping plan and prepare for the next block of vehicles

Basic Requirements:

3+ years of hands-on mechanical assembly experience in a shop, manufacturing, prototype, or vehicle environment

Experience using hand tools, power tools, torque tools, and common shop equipment

Ability to read mechanical drawings, assembly instructions, and torque specifications

Experience assembling complex mechanical systems such as vehicles, heavy equipment, rail systems, aerospace hardware, industrial machinery, or robotics

Comfortable working in a low-volume environment where processes are still being developed

Strong attention to detail, commitment to safety, and ability to communicate effectively with engineers

Ability to travel extensively to our contract manufacturer during active vehicle builds

Preferred Qualifications:

Evidence of exceptional ability through prior projects, vehicle builds, fabrication work, or completed products

Experience assembling rail vehicles, commercial vehicles, heavy equipment, aerospace systems, or other safety-critical hardware

Experience working with vehicle systems such as brakes, gearboxes, axles, suspension systems, or bogies

Experience supporting prototype, first-article, or new product introduction builds

Experience building engineering test benches, fixtures, or prototype hardware

Experience identifying design-for-assembly or manufacturing process improvements

Experience training, mentoring, or leading other technicians
