Job description

Lead - Test Development Roles & Responsibilities :

• Test Strategy & Development - Define and implement test strategies for PCBA and electronic products covering In-Circuit Test (ICT), Functional Circuit Test (FCT), and Flying Probe Test based on product complexity, test coverage, volume, and customer requirements.
• ICT Program Development - Develop, debug, validate, and optimize ICT programs for component presence, value, polarity, shorts, opens, analog parameters, and manufacturing defects using platforms such as Keysight, Teradyne, SPEA, or equivalent.
• Functional Test Development - Design and develop FCT solutions to verify PCB functionality, electrical performance, interfaces, communication protocols, firmware, and product-specific operating parameters.
• Flying Probe Test Development - Develop and optimize Flying Probe Test programs for prototypes, NPI builds, low-volume production, and PCBAs where dedicated ICT fixtures are not economical or practical.
• Test Fixture & Hardware Design - Lead fixture design, bed-of-nails development, interface hardware, test adapters, wiring, switching circuits, and mechanical integration to ensure repeatability, maintainability, and safe operation.
• Test Coverage & Quality Improvement - Establish test coverage requirements, identify undetected defect risks, optimize fault detection, and improve test effectiveness using defect data, boundary-scan methods, and design-for-test (DFT) reviews.
• NPI & New Product Introduction - Lead test readiness during NPI, including DFT reviews, testability assessment, prototype debugging, engineering validation, test correlation, and production release approval.
• Test Debugging & Failure Analysis - Analyze ICT, FCT, and Flying Probe failures; distinguish genuine PCB defects from false failures; perform root-cause analysis with Design, Process, Production, and Quality teams.
• Test Equipment Qualification & Validation - Ensure equipment calibration, GR&R where applicable, repeatability and reproducibility, measurement-system validation, golden-board verification, and preventive maintenance.
• Test Cycle-Time Optimization - Reduce test cycle time, improve throughput, minimize false failures and retesting, and align test capacity with production requirements and takt time.
• Test Software & Automation - Develop or oversee test sequences, scripts, drivers, communication interfaces, automated data acquisition, and test result logging using suitable programming tools and test platforms.
• Firmware & Communication Testing - Integrate firmware programming and validation, including UART, SPI, I²C, CAN, Ethernet, USB, and other product-specific interfaces where applicable.
• Test Data & Traceability - Implement unique PCBA serial-number traceability, automatic test-result capture, failure-code mapping, and integration with MES, ERP, and production databases.
