Senior ATE Test Engineer – Optical Transceiver Silicon

Lumilens; Singapore; On-site; SGD 130,000 - 210,000; Full time

Job summary

Lumilens designs optical interconnects for AI data centers, and this role owns test for the mixed-signal ICs at the heart of our co-packaged optics and transceivers. You will drive first-silicon bring-up through to production, collaborating with design, validation, and external test partners across the region.

You will develop and optimize ATE test programs, specify test hardware, and ensure correlation between bench and system-level performance.

Qualifications

• BS/MS in Electrical Engineering, Computer Engineering, Physics or related field.
• 8+ years developing production test for mixed-signal or high-speed ICs.
• Hands-on ATE experience on major platforms (Advantest 93K/T2000, Teradyne UltraFLEX/J750, Eagle, Chroma).
• Strong programming: C/C++ and Python, on Linux.
• Solid analog and mixed-signal fundamentals — read schematics, interpret datasheets.
• Practical test hardware skills: load board/probe card design review, signal integrity at speed, bench instrumentation.
• Statistical fluency for yield and correlation work — JMP, MATLAB, Python/pandas.
• Direct experience running programs at OSATs and managing external test partners.
• Willingness to travel regionally to test sites, overlapping with US/India hours when needed.

Responsibilities

• Own the test strategy for one or more ICs: coverage plan, test lists, insertion flow (wafer sort, final test, system-level).
• Develop, debug, and optimize ATE test programs for mixed-signal and high-speed devices — analog and DC parameters, high-speed signal path, on-chip test points, digital scan, and firmware-driven test modes.
• Specify and bring up test hardware: load boards, probe cards, socketing, and the opto-electrical fixturing our photonics-attached parts require. Work with vendors through layout, fab, and first article.
• Drive first-silicon bring-up alongside design and validation. Correlate ATE results to bench characterization and to system-level performance, and close the loop when they disagree.
• Own the relationship with our OSATs and test houses in the region: program release, correlation across testers and sites, multi-site and throughput optimization, capacity planning, and day-to-day production support.
• Analyze sort and final test data to find yield limiters, marginal tests, and guard-band problems. Lead failure analysis and root cause on returns and excursions.
• Set the standard for how test is done here — reusable test IP, data infrastructure, documentation, and review practice — and mentor junior test engineers as the Singapore team grows.
