Senior / Staff ATE Test Engineer – Optical Transceiver Silicon

The role

You will own the test strategy and development for mixed-signal ICs. This includes first-silicon bring-up, ATE test program optimization, and managing production programs at OSATs.

What you will do

• Own the test strategy for one or more ICs including coverage plan, test list, and insertion flow.
• Develop, debug, and optimize ATE test programs for mixed-signal and high-speed devices.
• Specify and bring up test hardware including load boards, probe cards, and socketing.
• Drive first-silicon bring-up alongside design and validation teams.
• Correlate ATE results to bench characterization and system-level performance.
• Own the relationship with OSATs and test houses in the region.
• Analyze sort and final test data to find yield limiters and lead failure analysis.
• Set the standard for test IP, data infrastructure, documentation, and review practice.
• Mentor junior test engineers as the Singapore team grows.

Required qualifications

• BS/MS in Electrical Engineering, Computer Engineering, Physics or a related field.
• 8+ years developing production test for mixed-signal or high-speed ICs.
• At least one program taken from first silicon through to high-volume production.
• Deep hands-on ATE experience on at least one major platform (Advantest 93K or T2000, Teradyne UltraFLEX or J750, Eagle, Chroma, or comparable).
• Strong programming in C/C++ and Python, on Linux.
• Solid analog and mixed-signal fundamentals.
• Practical test hardware skills including load board and probe card design review, signal integrity at speed, and bench instrumentation.
• Statistical fluency for yield and correlation work using JMP, MATLAB, Python/pandas, or equivalent.
• Direct experience running programs at OSATs and managing external test partners.
• Willingness to travel regionally to test sites.

Nice to have

• Established working relationships with OSATs and test houses in Singapore, Malaysia, Taiwan, or the Philippines.
• High-speed SerDes test experience at 100G/lane and above.
• Silicon photonics, optical transceiver, or opto-electrical test background.
• DFT familiarity: scan, MBIST, JTAG/IEEE 1149, on-chip instrumentation and monitors.
• STDF and test data pipelines.
• Experience defining test for a product line in its first generation.
