R&D Prototype Assembler

Job Description

Job Description

Th e Prototype Assembler (Contract)  is responsible for assembling and refining pre-production robotic systems with a strong emphasis on engineering collaboration. Working from early-stage documentation, CAD models, wiring diagrams, and verbal direction, this role integrates mechanical, electrical, and control components into functional prototypes. Beyond assembly, this position plays an active role in Design for “x” (DFx) initiatives, providing real-time manufacturability, serviceability, and quality feedback to engineering teams. This collaboration ensures that designs are optimized for efficient, reliable, and cost-effective production before scaling to manufacturing.

Key Responsibilities

●     Interpret and work from CAD models, engineering drawings, wiring schematics, and assembly instructions to build robotic prototypes and subsystems.

●     Assemble mechanical frames, integrate wiring harnesses, and install sensors, actuators, and control systems.

●     Partner closely with mechanical, electrical, and manufacturing engineers to evaluate designs for manufacturability, assembly efficiency, cost reduction, and serviceability (DFx).

●     Provide actionable feedback to improve part fit, alignment, accessibility, wiring routing, and overall build processes.

●     Perform rework, modifications, and functional testing to support rapid design iterations.

●     Document assembly processes, tooling requirements, and recommended design changes for future builds.

●     Conduct functional and performance tests to validate subsystem and system-level integration.

●     Maintain compliance with safety protocols when working with mechanical, electrical, and pneumatic systems.

●     Contribute to continuous improvement of prototype build processes and DFx review practices.

Core Competencies

●     Execution – Delivers precise, functional assemblies on schedule, incorporating engineering feedback loops into the build process.

●     Collaboration – Works as an extension of the engineering team, influencing design decisions through hands-on prototype assembly insights.

●     Innovation – Proactively identifies and tests assembly process improvements, tooling options, and design refinements for DFx compliance.

●     Adaptability – Rapidly adapts to evolving designs, emerging technologies, and shifting DFx priorities in a fast-paced robotics environment.

Knowledge, Skills & Abilities

●     Proficiency in interpreting mechanical and electrical drawings, wiring diagrams, and CAD-based assembly instructions.

●     Strong mechanical assembly, wiring, soldering, and electromechanical integration skills.
Knowledge of robotics components such as servos, gearboxes, actuators, embedded controllers, and cable management systems.

●     Ability to analyze and communicate manufacturability and assembly considerations to engineering teams.

●     Skilled in troubleshooting integration issues across mechanical, electrical, and control systems.

●     Understanding of ESD safety, tolerance stack-ups, and ergonomic considerations in assembly.

●     Familiarity with basic programming or test interfaces for hardware validation (preferred).

Typical Qualifications

●     High school diploma or equivalent; technical certification or associate degree in mechatronics, robotics, or related field preferred.

●     3–5 years in prototype assembly, ideally with DFx or engineering collaboration experience in robotics or automation.

●     IPC soldering certification, OSHA safety training, or robotics technician certification (preferred).
