Own Optical Transceiver ATE Test Programs

Lumilens; Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

Lumilens is building optical interconnects for AI data centers, delivering silicon in production clusters today. You will own production test programs for mixed-signal ICs, taking content from bench bring-up through OSAT release and maintaining it into production.

Based in Singapore, you will work hands-on with test partners, collaborating with design and validation teams across the US, India, and Singapore. You will grow into owning test architecture as we scale.

Qualifications

• 3–5 years developing production test for mixed-signal or high-speed ICs.
• At least one test program taken to production release.
• Hands-on ATE experience on major platforms (Advantest/Teradyne/Eagle/Chroma).
• Strong ability to read schematics and datasheets and design verifications.
• Collaborate with design, validation, OSAT partners; travel regionally.

Responsibilities

• Own test program development for assigned devices or blocks: build the test list against the coverage plan, and take it through wafer sort and final test insertions.
• Develop, debug, and optimize ATE test programs for mixed-signal and high-speed devices—analog, DC, high-speed paths, on-chip test points, and firmware-driven modes.
• Support test hardware bring-up: review load board designs, debug lab issues, and work with vendors on first article.
• Participate in first-silicon bring-up with design and validation; correlate ATE results with bench, investigate discrepancies.
• Be the day-to-day technical contact for programs at OSATs: release, cross-site correlation, production support.
• Analyze sort and final test data to identify yield limiters and drive fixes; support failure analysis.
• Build reusable test IP, scripts, and data tooling to accelerate the team.
