From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.\nWe’re a well-funded startup backed by Mayfield and led by veterans who’ve built and scaled some of the most transformative technologies in the industry.\nThis isn’t incremental innovation, it’s a ground-floor opportunity to rethink the optical layer from the silicon up. The market is moving fast, and we’re moving faster. You’ll work alongside a team of world-class engineers solving some of the hardest challenges in optics, systems, and scale. Every line of code, every design decision, every breakthrough you help deliver will shape the infrastructure of tomorrow.\nIf you're looking for mission, momentum, and the chance to make an outsized impact, jump on the rocket ship. We’re just getting started.\nAbout the Role\nYou own verification end to end for a first-of-its-kind chiplet. As a founding hire you define the methodology before there's RTL to verify - this role is on the critical path, and getting the coverage strategy and regression infrastructure right early is the single biggest schedule lever we have.\nAbout the role. You define the digital front-end micro-architecture - the spec the design team implements - and personally own the high-speed datapath that moves data between UCIe and the optical front end. This is the architectural center of the chip: the datapath, the UCIe streaming interface, in-house IP, and the interface to the optical engine all converge in your blocks. As a founding hire you set the partitioning, interfaces, and coding/CDC standards the whole front end follows.\nWhat you'll own\nFront-end micro-architecture and block partitioning; the architecture spec the RTL team builds to.\n\nFront-end design methodology and quality: RTL coding standards, lint, CDC/RDC signoff, and clean-RTL policy across the team.\n\nThe high-speed datapath: per-lane alignment/deskew/mux, the UCIe streaming /RDI adapter, elastic FIFOs, and custom logic.\n\nTransport/link framing/mapping and the adaptation logic.\n\nTiming- and floorplan-aware micro-architecture: pipelining, retiming, and partitioning for physical closure at multi-hundred-Gbps (with the backend team).\n\nClocking, reset, and low-power architecture - clock/reset domains, gating strategy, and UPF power intent.\n\nEstablish designer-level verification: block-level testbenches/sanity checks and assertion (SVA) coverage that designers own before handoff to DV.\n\nArchitectural DFT and debug provisioning - scan-friendly structure and on-die observability/controllability for a die you can't probe (with the DFT and DV leads).\n\nIP integration and interface/register conventions; parameterization for configurability across lane counts/configurations.\n\nArchitectural trade-offs with the modelling lead (latency, buffering, datapath sampling/observability) and the DV lead (verifiability and debug).\n\nLead, grow, and mentor the front-end design team as the group scales (datapath, interfaces, integration).\n\nRequired\n10+ years digital design / micro-architecture, with lead ownership of a high-throughput datapath or SerDes-adjacent SoC.\n\nExperience designing the datapath of a network switch/NIC card or memory controller at a major XPU / fabric vendor (or a comparable high-throughput, high-reliability datapath).\n\nSolid understanding of scale-up vs. scale-out interconnect architectures and their bandwidth/latency trade-offs.\n\nStrong SystemVerilog RTL and timing-aware micro-architecture at multi-hundred-Gbps aggregate rates; CDC discipline.\n\nWorking command of UCIe/PCIe/CXL datapath concepts and high-speed lane alignment/deskew.\n\nProven ownership of front-end design methodology - lint/CDC/RDC signoff, clocking/reset architecture, and design-for-test and physical-closure collaboration.\n\nTrack record translating system requirements into an implementable, verifiable architecture spec.\n\nPreferred\nUCIe (or PCIe/CXL/CHI) interface architecture; die-to-die / chiplet experience.\n\nFEC/coding datapath familiarity (e.g., Reed-Solomon) and gray-code mapping.\n\nOptical transceiver, CPO, or linear-drive optics background; advanced-node (N5/N3/N2) design experience.\n\nWhat We Offer\nCompetitive salary commensurate with experience\n\nComprehensive benefits package including health, dental, and vision\n\nProfessional development opportunities and certification support\n\nAccess to cutting-edge technology and cloud platforms\n\nCollaborative work environment with cross-functional teams\n\nLumilens is an equal opportunity employer. All qualified applicants will receive consideration without regard to race, color, religion, gender identity, sexual orientation, veteran status, disability, or any other legally protected status.","description_format":"text","description_chars":4883,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Servers & Data Center Hardware","Optical Communications","Optics & Photonic Components"],"lifecycle":[{"event":"open","at":"2026-09-10T18:47:58Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":0.4,"p_active":0.831,"p_room":0.44,"age_days":130,"expected_fill_days":118,"reasons":["seen:130","velocity","win:tail","crowd:brand"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/lumilens-rtl-design-leadic-front-end-architectdatapath-lead","json_url":"https://alion.io/job/lumilens-rtl-design-leadic-front-end-architectdatapath-lead.json","meta":{"generated_at":"2026-11-03T02:35:21Z","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":3419,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"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":678172},"rest":"https://alion.io/mcp/rest/get_company?id=678172"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flumilens-rtl-design-leadic-front-end-architectdatapath-lead"},{"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%2Flumilens-rtl-design-leadic-front-end-architectdatapath-lead"},{"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%2Flumilens-rtl-design-leadic-front-end-architectdatapath-lead"},{"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-rtl-design-leadic-front-end-architectdatapath-lead\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flumilens-rtl-design-leadic-front-end-architectdatapath-lead"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":621934}},{"tool":"search_jobs","arguments":{"company":"lumilens.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":621934},"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.
