Requirements

• BS/MS in Electrical Engineering, Computer Engineering, Physics, or a related field. • 3–5 years developing production test for mixed-signal or high-speed ICs, including at least one test program you took to production release. • Hands-on ATE experience on at least one major platform (Advantest 93K or T2000, Teradyne UltraFLEX or J750, Eagle, Chroma, or comparable). • Strong programming: C/C++ and Python, on Linux. You write test code other engineers can read and extend. • Solid analog and mixed-signal fundamentals — you can read a schematic, reason about a datasheet spec, and design the measurement that proves it. • Practical test hardware skills: load board and probe card debug, bench instrumentation (scopes, BERTs, SMUs, network analyzers, VNAs), and lab troubleshooting. • Working knowledge of optical systems and networks: how an optical transceiver works, optical power and link budgets, and high-speed serial protocols such as Ethernet and PAM4 signaling. • Statistical fluency for yield and correlation work — JMP, MATLAB, Python/pandas, or equivalent. • Some exposure to OSAT or subcontract test operations, and comfort working with external partners. • Willingness to travel regionally to test sites, and to overlap with US and India hours when a bring-up or an excursion calls for it. • Silicon photonics, optical transceiver, or opto-electrical test background — coupled-fiber test, optical power and wavelength measurement, TIA and driver characterization. • High-speed SerDes test experience: BER, jitter decomposition, eye margining, loopback methods. • DFT familiarity: scan, MBIST, JTAG/IEEE 1149, on-chip instrumentation and monitors. • STDF and test data pipelines; building analytics that engineers actually use. • Experience supporting a product through its first production ramp.

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 and DC parameters, high-speed signal path, on-chip test points, digital scan, and firmware-driven test modes. • Support test hardware bring-up: review load board and probe card designs, debug hardware issues in the lab, and work with vendors through first article. • Participate in first-silicon bring-up alongside design and validation. Correlate ATE results to bench characterization, and investigate when they disagree. • Be the day-to-day technical contact for your programs at our OSATs: release, correlation across testers and sites, multi-site and test time optimization, and production support. • Analyze sort and final test data to find yield limiters, marginal tests, and guard-band problems. Drive the fixes on your devices and support failure analysis on returns and excursions. • Build the reusable test IP, scripts, and data tooling that make the whole team faster.

Benefits

• Optical I/O for AI is being defined right now, and test is one of the places where it is won or lost — a part that cannot be screened economically does not ship, however good the design. The team is small, so your programs are yours: you will see your test content go from a bench setup to millions of parts, and grow into owning test architecture as we scale.
