The company combines custom silicon, integrated sensors, and software into a unified platform for robotics, mobility, and next-generation automation. Lyte is headquartered in Sunnyvale, California, with a global presence. For more information, visit www.lyte.ai\nIf you’re excited about building impactful technology in a dynamic, hands-on environment, we’d love to hear from you!\nAbout the role\nWe are seeking an experienced Wafer-Level Test (WLT) Engineer/Lead based in Taiwan (Hsinchu area preferred). You will own wafer-level (CP / wafer sort) test for Lyte's custom mixed-signal CMOS silicon, the chips at the heart of our products. You will develop, validate, and maintain ATE wafer-level test programs with Lyte's test house partners, and transfer released programs to OSAT partners for volume production. \nWhat you'll do\nOwn wafer-level (CP / wafer sort) test at Lyte's Taiwan test house partners, managing test program development, engineering lots, and production wafer sort.\nDevelop ATE wafer-level test programs for mixed-signal CMOS on Advantest V93000 or Teradyne platforms. This covers test program architecture, test flows, pin/levels/timing set-ups, binning, and limits tables.\nWork daily with Lyte's chip design team at our US headquarters to translate design into test plans, test specifications, and test coverage matrices.\nImplement and debug BIST, scan/DFT, analog and mixed-signal parametric tests, and OTP/eFuse trimming routines.\nValidate test programs before first silicon using offline/virtual tester environments and pattern conversion (WGL/STIL/VCD) from design simulation.\nBring up new silicon on the tester, covering first-silicon debug, characterization, and correlation between bench, ATE, and simulation results.\nMaintain released programs across their lifecycle, with full regression and sign-off. This covers change requests, limit updates, bug fixes, test-time reduction, and yield improvements.\nTransfer released test programs to OSAT partners for volume production. This includes tester-to-tester and site-to-site correlation, GR&R, golden-wafer checks, and production release readiness.\nDeploy and maintain test programs at partner sites, including production issue triage, excursion response, and root cause and corrective action (8D / 5-Why).\nWork with partners on probe card specification and qualification, prober set-up, contact/overdrive optimization, and tester hardware debug.\nAnalyze wafer test data (STDF, wafer maps, bin Paretos, Cp/Cpk) to monitor yield, detect excursions, and drive yield and test-time improvements.\nExtend Lyte's capability into advanced wafer-level test as programs mature, including optical wafer-level test, working with partners on test methods, hardware, and correlation.\nOwn test documentation and version control so every build is traceable and reproducible across partner sites. Report regularly on test development, yield, and production readiness to engineering and operations leadership.\nTravel to test house and OSAT facilities in Taiwan and across Asia as needed to resolve issues and support production ramps.\nRequired Qualifications\nBachelor's degree in Electrical Engineering, Electronics, Computer Engineering, Physics, or a related field.\n5+ years of hands-on ATE test program development for mixed-signal CMOS ICs, including direct wafer-level (CP / wafer sort) experience.\nHands-on experience with Advantest V93000 (SmarTest) and/or Teradyne (UltraFLEX, J750, or similar) platforms.\nWorking knowledge of BIST/DFT test methods and OTP/eFuse trimming at wafer level.\nExperience validating test programs pre-silicon in collaboration with chip design teams.\nProven experience maintaining production test programs and supporting OSATs or test houses, including program transfer and correlation.\nProgramming in C/C++ and/or Java (SmarTest) or VB/VBT (IG-XL). Python or Perl scripting is a plus.\nSolid data analysis skills: STDF, wafer maps, yield Paretos, Cp/Cpk, and GR&R.\nDisciplined documentation, version control (e.g., Git/SVN), and change-management practices.\nStrong written and spoken English to work with HQ engineers across time zones, plus Mandarin fluency to work with local partners.\nOwnership mindset and strong teamwork. You are comfortable working independently at partner sites and willing to travel regularly within Taiwan and occasionally across Asia.\nPreferred Qualifications\nMaster's degree in Electrical Engineering or a related field.\nExperience as a test lead, owning test strategy and coordinating multiple test house and OSAT partners.\nFamiliarity with probe card design and qualification, load boards, and prober set-up and cleaning recipes.\nPrior experience at, or working closely with, a Taiwan test house or OSAT.\nExperience with test-time reduction, multi-site test development, and adaptive test / outlier screening (e.g., Part Average Testing).\nExperience with yield-management and analysis tools (e.g., JMP, Spotfire, or similar).\nExperience testing analog/mixed-signal blocks such as ADCs/DACs, PLLs, LDOs, bandgaps, and high-speed interfaces.\nKnowledge of automotive quality standards such as AEC-Q100.\nExperience with known-good-die (KGD) screening and advanced-packaging wafer-level test.\nExperience with, or strong interest in, optical and silicon photonics wafer-level test.\nFamiliarity with lidar, FMCW, photonics, or robotics sensor technologies.\nBenefits (subject to location and local regulations)\nCompetitive salary and equity \nFlexible vacation and time-off policy \nCollaborative, fast-paced, and inclusive work environment \nOpportunity to work on cutting-edge technologies with a highly cross-functional team","description_format":"text","description_chars":5732,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-02T08:38:29Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":4,"expected_fill_days":35,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-10-06T05:45:30Z"},"pay":null,"html_url":"https://alion.io/job/lyte-wafer-level-test-engineerlead","json_url":"https://alion.io/job/lyte-wafer-level-test-engineerlead.json","meta":{"generated_at":"2026-10-07T01:06:59Z","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","counted_by":"address","units_charged":1,"used_today":1898,"day_limit":5000,"remaining_today":3102,"minute_limit":60,"resets_at":"2026-10-08T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"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":30000},"rest":"https://alion.io/mcp/rest/get_company?id=30000"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flyte-wafer-level-test-engineerlead"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"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%2Flyte-wafer-level-test-engineerlead"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"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%2Flyte-wafer-level-test-engineerlead"},{"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/lyte-wafer-level-test-engineerlead\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flyte-wafer-level-test-engineerlead"}]}
