Job summary

Fractile is seeking a board/test engineer to develop and maintain automated test content for high-power, high-speed boards used in frontier AI hardware. You will implement ICT, boundary scan, and functional tests, build fixtures, and firmware for manufacturing diagnostics.

You will collaborate with hardware, firmware, and SI/PI teams, analyze failures, and help raise test coverage and throughput across offshore EMS/CM sites, contributing to robust production testing.

Qualifications

• 4-7 years in board/PCBA test engineering in high-volume manufacturing.
• Hands-on with functional test development, ICT, and boundary scan/JTAG.
• Experience designing or supporting test fixtures and automated test stations.
• Knowledge of high-speed digital interfaces and board-level failure modes.
• Experience developing embedded test firmware on MCUs.
• Strong debugging across digital logic, power delivery, and interconnect issues.
• Ability to work with offshore manufacturing partners.

Responsibilities

• Develop and maintain board test content for high-power boards.
• Implement and debug test coverage across ICT, boundary scan/JTAG, and functional test stages.
• Design and support board-level test solutions including fixtures, probes, cabling, and instrumentation.
• Develop 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.
• 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.
