Our silicon ships in production AI clusters today, and volume is climbing fast.\nYou 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.\nSingapore 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.\nThis is the role where you go from executing someone else's test plan to owning your own.\nWhat you'll do\nOwn 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.\n\nDevelop, 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.\n\nSupport test hardware bring-up: review load board and probe card designs, debug hardware issues in the lab, and work with vendors through first article.\n\nParticipate in first-silicon bring-up alongside design and validation. Correlate ATE results to bench characterization, and investigate when they disagree.\n\nBe 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.\n\nAnalyze 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.\n\nBuild the reusable test IP, scripts, and data tooling that make the whole team faster.\n\nWhat we're looking for\nBS/MS in Electrical Engineering, Computer Engineering, Physics, or a related field.\n\n3-5 years developing production test for mixed-signal or high-speed ICs, including at least one test program you took to production release.\n\nHands-on ATE experience on at least one major platform (Advantest 93K or T2000, Teradyne UltraFLEX or J750, Eagle, Chroma, or comparable).\n\nStrong programming: C/C++ and Python, on Linux. You write test code other engineers can read and extend.\n\nSolid analog and mixed-signal fundamentals - you can read a schematic, reason about a datasheet spec, and design the measurement that proves it.\n\nPractical test hardware skills: load board and probe card debug, bench instrumentation (scopes, BERTs, SMUs, network analyzers, VNAs), and lab troubleshooting.\n\nWorking 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.\n\nStatistical fluency for yield and correlation work - JMP, MATLAB, Python/pandas, or equivalent.\n\nSome exposure to OSAT or subcontract test operations, and comfort working with external partners.\n\nWillingness to travel regionally to test sites, and to overlap with US and India hours when a bring-up or an excursion calls for it.\n\nPreferred Qualifications\nSilicon photonics, optical transceiver, or opto-electrical test background - coupled-fiber test, optical power and wavelength measurement, TIA and driver characterization.\n\nHigh-speed SerDes test experience: BER, jitter decomposition, eye margining, loopback methods.\n\nDFT familiarity: scan, MBIST, JTAG/IEEE 1149, on-chip instrumentation and monitors.\n\nSTDF and test data pipelines; building analytics that engineers actually use.\n\nExperience supporting a product through its first production ramp.\n\nWhy this role\nOptical 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.","description_format":"text","description_chars":4293,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Optical Communications","Servers & Data Center Hardware","Optics & Photonic Components"],"lifecycle":[{"event":"open","at":"2026-09-16T03:28:29Z"},{"event":"open","at":"2026-10-22T01:42:57Z"}],"visa":[],"liveness":{"score":58,"band":"ok","label":"Likely open","p_open":1,"p_active":0.802,"p_room":0.72,"age_days":57,"expected_fill_days":118,"reasons":["conf:0","win:mid","crowd:brand"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/lumilens-ate-test-engineer-optical-transceiver-silicon","json_url":"https://alion.io/job/lumilens-ate-test-engineer-optical-transceiver-silicon.json","meta":{"generated_at":"2026-11-14T02:14:41Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":2794,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":678172},"rest":"https://alion.io/mcp/rest/get_company?id=678172"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flumilens-ate-test-engineer-optical-transceiver-silicon"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Flumilens-ate-test-engineer-optical-transceiver-silicon"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Flumilens-ate-test-engineer-optical-transceiver-silicon"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/lumilens-ate-test-engineer-optical-transceiver-silicon\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flumilens-ate-test-engineer-optical-transceiver-silicon"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":953974}},{"tool":"search_jobs","arguments":{"company":"lumilens.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":953974},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
