    • Work with manufacturing engineer to resolve manufacturing defects caught at test.

    • Work with customer to highlight design issues and manage resolution.

    • Verify test set up and provide enhancements through procedural, mechanical or automation software additions to improve yields and test process.

    • Review NFF and False Fails and develop/ establish test recommendations to address, optimize or eliminate.

  • Analyze, debug and support “non-functional” test stations, fixtures and equipment and establish a plan to minimize down time.

  • Mentor/Train test engineers and technicians on performing test process, provide additional documentation if needed.

  • Ensure the safety of the test operator and/or technician is designed into the test process and never jeopardized.

  • Evaluate test cycle times and provide a capacity measurement report for stations and manpower based on product demand loaded.

  • Interface with customer and on-site engineering team to improve test coverage.

  • Evaluate customer Engineering Change Orders (ECOs), identify hardware and software impact on test process, provide cost/labor changes if applicable; implement ECO when all technical/cost related items are submitted and resolved.

  • Validate/Update test programs with customer Engineering Change Notice (ECN) - Altering the test programs to meet new customer test requirements.

  • Backup all test programs – Ensure a spare copy for test programs is available or obtain from installation s/w from customer or development group, if not stored on the network.

  • Ensure/Prepare a list of necessary spares used on the test stations such as cables, connectors and test equipment to reduce down time.

  • Support Test FMEA, Cpk, Gauge R&R and related Functional Test Acceptance and Release criteria.

  • Work with program management and manufacturing coordinating and implementing activities to support successful new product launches.
