Job description

POSITION SUMMARY

Responsible for the end-to-end design, development, and validation of high-precision jigs and fixtures specifically for gadget manufacturing. This role bridges the gap between customer concepts and shop-floor execution, ensuring that all tooling meets stringent precision, repeatability, and "First Article" success standards.

CORE RESPONSIBILITIES

• Technical Analysis & Customer Liaison3D Model Study:Perform a detailed audit of customer-provided 3D models / 2D drawings to identify assembly constraints and critical dimensions.Gap Analysis:Detect DFM/DFA gaps and communicate directly with the customer to resolve technical ambiguities.Acceptance Criteria:Define the specific performance and quality benchmarks for each fixture.
• Design & Component SelectionBOP Management:Select and specify Bought-Out Parts (BOP), including identifying equivalent makes to optimize cost and lead times.Mechanical:Precision bearings, linear rails, and slide ways.Pneumatics:Cylinders, DCV valves, and manifold systems.Automation:PLCs, HMI units, and sensors (Proximity, Optical, Magnetic).Electrical:Switches, push buttons, and wiring harnesses.
• Documentation & StandardsAssembly Guides:Create visual, step-by-step assembly instructions for the toolroom.Check Sheets:Develop comprehensive inspection check sheets to verify fixture build quality.
• Execution & ValidationTroubleshooting:Lead the technical debugging of fixtures during the assembly and testing phases.FAI Support:Actively support the assembly team during First Article Inspection (FAI) to ensure the fixture delivers parts that meet 100% of customer specifications.TECHNICAL SKILLS & QUALIFICATIONSCAD Mastery:Expert-level proficiency in 3D modeling software (e.g., SolidWorks, CATIA, or NX).Pneumatic/Electrical Logic:Ability to design actuation sequences and sensor integration for automated fixtures.Analytical Thinking:Strong root-cause analysis skills for troubleshooting mechanical misalignments.Precision Focus:Deep understanding of tolerance stack-up and high-precision manufacturing techniques.KEY PERFORMANCE INDICATORS (KPIs)Fixture Accuracy:Zero deviation from defined Acceptance Criteria.FAI Success Rate:Achieving "Right First Time" on First Article Inspections.Documentation Clarity:Zero errors in Assembly Instructions and Check Sheets.
