Develop and own production test programs for mixed-signal ICs in optical transceiver silicon.
Обязанности
- builds optical interconnect for AI data centers: silicon photonics, mixed-signal ICs, electrical-optical interposers, and the systems around them. Our silicon ships in production AI clusters today, and volume is climbing fast.
- You will develop and own production test programs for our mixed-signal ICs — the SerDes, TIAs, modulator drivers, and control silicon at the heart of our co-packaged optics and pluggable transceivers. You will take test content from bring-up on the bench through to release at the OSAT, and stay with it through production.
- Singapore puts you inside the assembly and test supply chain we depend on. You will be hands-on with our test partners in the region, working alongside a senior test engineer and partnering with design and validation teams across the US, India, and Singapore.
- This is the role where you go from executing someone else's test plan to owning your own.
- 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.
Требования
- 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.
Будет плюсом
- 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.
Другое
- 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.
