Who We Are
Sonnax provides innovative transmission repair products for the automotive aftermarket and industrial sectors utilizing drivetrain components. 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 is responsible for planning, machining, modifying, and supporting the manufacture of prototype and pilot lot components for new products. This role is the hands on bridge between engineering design and full scale production-turning early concepts, drawings, and models into high quality physical parts. The machinist works closely with Design Engineering, Manufacturing, Quality, Supply Chain, and Operations to accelerate development cycles and support smooth product launches.
This position is ideal for a highly skilled machinist who enjoys problem solving, collaborating across departments, and taking ownership of a part, from concept to finished component.

Key Responsibilities

Prototype & Pilot Lot Machining

• Set up and operate manual and CNC machines (mills, lathes, wire EDM, etc.) to produce prototype and pilotlot components.
• Machine parts from engineering drawings, 3D models, sketches, or verbal instructions in a lowvolume, highvariation environment.
• Support rapid design iterations, rework, and engineering changes during prototype and pilot builds.

• Maintain dimensional accuracy and quality while working with evolving designs and limited documentation.
• Identify and resolve machining and manufacturability issues related to materials, tooling, tolerances, and part geometry.

Engineering & Manufacturing Support

• Work directly with Design Engineers to clarify design intent and understand functional requirements.
• Provide practical designformanufacture feedback to improve machinability, reduce risk, and optimize parts for available equipment.
• Review drawings and models to highlight manufacturability concerns, tolerance challenges, and tool access limitations.
• Troubleshoot machiningrelated issues that impact assembly, fit, or function during prototype and pilot builds.

CrossFunctional Collaboration

• Work with Quality to inspect prototype and pilot components using precision measurement tools and ensure compliance with design requirements.
• Partner with Design Engineering to improve manufacturability, assembly, and testability of new components.
• Coordinate with Supply Chain to source prototype materials, tooling, and outsourced processes.
• Collaborate with inhouse manufacturing teams to schedule or execute processes requiring additional capabilities or capacity.
• Assist in coordinating prototype and pilot builds with external vendors when specialized machining or processing is required.

Documentation & Knowledge Transfer

• Capture lessons learned from prototype and pilot builds and communicate them to production teams.
• Support rootcause analysis and corrective actions for machiningrelated issues.
• Contribute to the transition from pilot to production, including documentation of setups, tooling, and process notes.

Continuous Improvement

• Support lean manufacturing initiatives and continuous improvement projects related to new product introduction.
• Identify opportunities to improve machining methods, setup efficiency, cost, quality, delivery, and safety.
• Maintain a clean, organized, and safe work area in compliance with shop safety standards.

Required Qualifications

• Strong ability to read and interpret engineering drawings, GD&T, and basic 3D models.
• Proficiency in manual and/or CNC machining, including setup and operation.
• Experience machining a variety of materials (steel, aluminum, plastics, etc.).
• Strong mechanical aptitude and problemsolving skills.
• Effective communication skills and ability to work collaboratively with engineering, manufacturing, and vendors.
• Ability to manage multiple prototype jobs and adapt to changing priorities.

Preferred Qualifications

• Experience supporting prototype, pilot, or lowvolume manufacturing builds.
• Familiarity with CAD/CAM software (viewing or basic programming).
• Exposure to quality systems and inspection requirements.
• Experience with lean manufacturing or continuous improvement tools.

What Success Looks Like in This Role

• Prototype and pilot builds are completed on schedule with minimal disruption.
• Manufacturing issues are identified early and resolved before production launch.
• Products transition smoothly from design to fullscale manufacturing.
• Crossfunctional teams view this role as a trusted, goto machining and manufacturability partner during new product development.
