Description
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 &
