Partnering with transmission rebuilders, our R&D teams identify failing OEM parts and design components to repair or enhance automatic transmissions, meeting a wide range of performance and warranty needs.

Summary:

The Rapid Product Development Machinist/Engineer is responsible for machining, modifying, planning, executing, and supporting the manufacture of prototype and pilot-lot components for new products. This role serves as the critical bridge between engineering design and full-scale production, translating engineering designs into high quality physical parts, focusing on speed-to-market to meet immediate customer needs. The machinist/engineer works cross-functionally with Design Engineering, Manufacturing Engineering, Product Line Managers, Quality, Supply Chain and Operations to support successful product development and production launch.

Key Responsibilities:

Prototype & Pilot Lot Machining

• Set up and operate manual and/or CNC machines (e.g., mills, lathes, wire EDM) to produce prototype and pilot-lot components
• Machine parts from engineering drawings, models, sketches, or verbal instructions in low-volume and high-variation environment
• Support rapid iterations, rework, and design changes during prototype and pilot builds
• Maintain dimensional accuracy and quality while working with evolving designs
• Identify and resolve manufacturing issues related to process capability, material availability, tooling, and product design

Engineering & Manufacturing Support

• Collaborate with Design and Manufacturing Engineers to clarify design intent and manufacturing processes and requirements to support new product development and product changes
• Collaborate with Design Engineers on component functionality and manufacturing feasibility to optimize design for manufacturability or for the equipment available.
• Provide feedback on part manufacturability, tolerances, tool access, and process feasibility
• Support prototype and pilot builds by troubleshooting machining-related issues impacting assembly or function

Cross-Functional Collaboration

• Partner with Design Engineering to improve manufacturability, assembly, and testability
• Coordinate with Quality to inspect prototype and pilot components using precision measuring tools and to ensure they meet design requirements
• Coordinate with Supply Chain to source prototype materials, components and tooling
• Coordinate with the in-house manufacturing team to schedule or execute processes that require additional capabilities or capacity.
• Assist in the coordination and execution of prototype and pilot builds requiring external manufacturers

Documentation & Knowledge Transfer

• Capture lessons learned from prototype and pilot builds and transfer knowledge to production teams
• Support root cause analysis and corrective actions for machining-related issues
• Support transition from pilot to production, including production readiness reviews and launch support

Continuous Improvement

• Identify opportunities to improve machining methods, setup efficiency, cost, quality, delivery, and safety in low-volume and production environments
• Support lean manufacturing initiatives and continuous improvement projects related to NPI

Maintain a clean, organized, and safe work area in compliance with shop safety standards

Required Qualifications

• BS degree in Manufacturing Engineering, Mechanical Engineering, Industrial Engineering, or a related field
• Strong ability to read and interpret engineering drawings, GD&T, and basic CAD models
• Proficiency with manual machining and/or CNC machining (setup and operation)
• Experience working with a variety of materials (steel, aluminum, plastics, etc.)
• Strong mechanical aptitude, problem-solving and analytical skills
• Excellent communication skills and ability to work effectively in cross-functional teams

Preferred Qualifications

• Experience supporting prototype, pilot, or low-volume manufacturing builds
• Familiarity with CAD/CAM software
• Exposure to quality systems and inspection requirements
• Experience with lean manufacturing or continuous improvement tools

Physical / Work Environment

• Regular work in a machine shop or prototype lab environment
• Ability to stand for extended periods and operate machine tools
• Lifting of materials or components and use of hand tools and measuring equipment

What Success Looks Like in This Role

• Prototype and pilot builds are executed on schedule with minimal disruption
• Manufacturing issues are identified early and resolved before production launch
• Products transition smoothly from design to full-scale manufacturing
• Cross-functional teams view this role as a trusted manufacturing partner during new product development
