Board Test Engineer

Responsibilities

• Develop and maintain board/PCBA manufacturing test content for complex, high-power, high-speed boards
• Implement and debug test coverage across ICT, boundary scan/JTAG, and functional test stages
• Design and support board-level functional test solutions, including fixtures, probes, cabling, and instrumentation
• Develop and maintain MCU-based board test firmware for manufacturing diagnostics, self-test, and telemetry validation
• Implement tests for detecting assembly defects, component failures, solder issues, and manufacturing marginalities
• Develop PCIe-focused board-level tests to verify chip-to-chip connectivity and integrity
• Support bring-up and debug of board test stations at offshore EMS/CM sites
• Analyze test failures and yield data to identify root causes and recommend corrective actions
• Work closely with hardware, firmware, and SI/PI teams to close board-level testability gaps
• Contribute to test documentation including test specifications, debug procedures, and manufacturing release notes
• Support fixture qualification, tester correlation, and ongoing test maintenance

Requirements

• 4–7 years of experience in board or PCBA test engineering in a high-volume manufacturing environment
• Hands-on experience with functional test development, ICT, and boundary scan/JTAG
• Experience designing or supporting test fixtures and automated test stations
• Working knowledge of high-speed digital interfaces and board-level failure modes
• Experience developing or supporting embedded test firmware on MCUs
• Strong debug skills spanning digital logic, power delivery, and interconnect issues
• Ability to work effectively with offshore manufacturing partners

Preferred Qualifications

• Experience testing boards with AI accelerators, GPUs, networking ASICs, or similar high-power devices
• Familiarity with high-current VRMs, multiphase power converters, and power integrity testing
• Exposure to PCIe Gen5/Gen6 or other high-speed serial links in a production test environment
• Experience using factory data systems and yield analysis to improve test coverage and throughput
• Experience supporting board test during NPI, ramp, and sustained production
