Senior Electrical, Hardware Design Engineer

aac technologies pte. ltd.; Singapore; On-site; SGD 90,000 - 120,000; Full time

Job summary

AAC Technologies Pte. Ltd. in Singapore seeks an experienced Electrical Test Engineer to design and optimize test structures and automate wafer-level electrical testing.

You will perform DC/AC/RF characterization and collaborate with Process Integration and Product Engineering to drive device performance and yield. The role requires 5+ years in semiconductor electrical testing, solid device physics knowledge, and hands-on experience with Keysight/Keithley equipment and wafer probing systems.

Qualifications

• Bachelor’s or Master’s Degree in Electrical/Electronics Engineering or related discipline.
• At least 5 years of experience in semiconductor electrical testing, wafer characterization, or device engineering.
• Strong understanding of semiconductor device physics (MOSFETs, diodes, leakage, threshold voltage, reliability concepts).
• Hands-on with semiconductor test equipment such as Keysight/Keithley or equivalent, and wafer probing systems.
• Experience with PCB layout/design tools (Altium, PADS, Cadence Virtuoso, KLayout).
• Experience with Automated Test Equipment (ATE) and wafer sort testing is an advantage.
• Knowledge of SPC and data analysis tools (JMP, Minitab, Spotfire) preferred.

Responsibilities

• Design electrical test structures and scribe-line test vehicles for wafer process monitoring.
• Perform electrical characterization including DC/AC parametric testing and RF measurements with automated wafer probe stations.
• Develop and optimize automated electrical test hardware and equipment (SMUs, oscilloscopes, network analyzers).
• Analyze electrical test data to identify process variations and improve yield and device performance.
• Support failure analysis by investigating electrical defects (shorts, opens, leakage).
• Collaborate with Process Integration and Product Engineering to achieve manufacturing goals.
• Prepare and submit BOMs for development projects.
