Test Engineer

Job Summary

We are seeking a hands-on Test Engineer with experience in semiconductor testing and Automatic Test Equipment (ATE). The successful candidate will be responsible for test program development, first-silicon debug, device characterization, production release, yield improvement and test-time optimisation for Digital, PMIC, RF and Mixed-Signal semiconductor products.

Key Responsibilities

• Develop and maintain semiconductor test programs for Digital, PMIC, RF and Mixed-Signal products using ATE platforms.
• Develop and debug test programs primarily on Advantest 93K with SmarTest 7 / SmarTest 8 and/or Teradyne UltraFLEX.
• Work closely with Design Engineers during first-silicon debug, device characterization, test program bring-up and production release.
• Debug digital test vectors including JTAG, SCAN, ATPG, Functional and MBIST.
• Perform device characterization across PVT (Process, Voltage and Temperature) conditions.
• Support characterization of Mixed-Signal IP including ADC, DAC, PLL and related circuits.
• Develop, debug and optimise test methodologies to improve product quality and test coverage.
• Analyse test data and identify opportunities for yield improvement and test-time reduction.
• Support test program hand-off from engineering development to high-volume production.
• Investigate test failures and perform root-cause analysis in collaboration with Design, Product and Quality Engineering teams.
• Support production test issues, yield excursions and test-related failure analysis.
• Prepare and maintain test specifications, test plans, test programs, characterization reports and technical documentation.
• Participate in engineering builds, product qualification and production release activities.
• Collaborate with cross-functional teams including Product Engineering, Design Engineering, Quality Engineering and Foundry Engineering.
• Perform hands-on laboratory testing, debugging and measurement activities using relevant test and measurement equipment.
• Support continuous improvement of semiconductor test processes, methodologies and test coverage.

Job Requirements

• Diploma or Bachelor's Degree in Electronics Engineering, Electrical Engineering, Microelectronics, Semiconductor Engineering or a related discipline.
• 2–5 years of relevant semiconductor Test Engineering experience preferred.
• Hands-on experience with Teradyne UltraFLEX and/or Advantest 93K ATE is highly advantageous.
• Experience with SmarTest 7 and/or SmarTest 8 is an advantage.
• Good understanding of analog and digital electronics.
• Knowledge of semiconductor testing, device characterization and production test methodologies.
• Understanding of Digital, Mixed-Signal, PMIC and/or RF device testing.
• Knowledge of JTAG, SCAN, ATPG, Functional Test and MBIST is advantageous.
• Understanding of PVT characterization and semiconductor test data analysis.
• Experience in test program development, debug and production release is preferred.
• Strong analytical, troubleshooting and problem-solving skills.
• Ability to perform hands-on debugging and testing in a laboratory environment.
• Good written and verbal communication skills.
• Ability to work independently as well as collaboratively in a cross-functional engineering environment.
• Willingness to support engineering and production activities as required.
