The Senior Prototype Technician – Mechanical Builds is a highly skilled hands-on expert responsible for leading complex prototype vehicle and subsystem assemblies within R&D and product development environments. This role involves advanced mechanical integration, low-volume fabrication, technical troubleshooting, and support for engineering evaluations. The technician plays a key role in bridging design intent and real-world functionality, while mentoring junior staff and ensuring high-quality, safe build execution.
Key Responsibilities:
Lead mechanical assembly and integration of advanced prototype vehicles, test rigs, and mechanical subsystems.
Interpret and provide feedback on detailed CAD drawings, BOMs, and mechanical design concepts.
Modify, fabricate, and fit components for one-off builds, including brackets, housings, and mockups.
Oversee fit-and-function checks, alignments, and adjustments for mechanical systems (powertrain, chassis, HVAC, etc.).
Identify and troubleshoot mechanical interface issues, providing hands-on solutions and design improvement feedback.
Collaborate closely with engineering, test, and validation teams throughout build and test cycles.
Document build processes, deviations, and rework; ensure alignment with prototype quality and safety standards.
Mentor and train junior and mid-level technicians on mechanical build best practices, tool use, and safety.
Key Focus Areas:
Leadership in mechanical assembly for prototype and pre-production vehicles
Low-volume fabrication and modification of mechanical parts
Cross-functional collaboration with engineering and R&D teams
