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. You will build the executable model of the chip before silicon exists. Your architecture models will settle the decisions that are expensive to change late, including datapath latency, throughput, buffer sizing, and control-loop tuning. Your reference models will become the golden checkers the verification team scores against, and the platform will run real firmware months ahead of RTL. This is a founding, critical-path role: the virtual platform is what unblocks the firmware and architecture work in parallel with design.\nWhat You'll Own\nA SystemC/TLM-2.0 virtual platform - MCU (ISS-backed) + peripherals + memory map + a UCIe transactor + host stub - that firmware runs on pre-RTL.\n\nArchitecture/performance models: architectural trade studies, end-to-end datapath throughput and latency, FIFO/buffer sizing, design-space/configuration exploration.\n\nGolden reference models handed to DV as scoreboards.\n\nBehavioral models of the analog and control circuits.\n\nPartner with the FE architect and firmware lead to keep model, RTL, and firmware views coherent.\n\nRequired\n8+ years in architecture/performance modelling or virtual-platform development for complex SoCs.\n\nStrong SystemC and TLM-2.0; solid modern C++.\n\nBuilt or led a virtual platform / ESL model that real firmware ran on for pre-silicon bring-up.\n\nIntegrating a third-party ISS (e.g., Arm or RISC-V) into a SystemC/TLM platform; modelling buses, memory maps, and peripherals.\n\nArchitecture/performance modelling judgment - knowing what to abstract versus model faithfully.\n\nComfortable spanning hardware micro-architecture and embedded software.\n\nPreferred\nFamiliarity with High-speed serial links and die-to-die / chiplet interconnects, and link-layer concepts such as FEC and equalization (e.g. PCIe, UALink, Ethernet or memory-semantic interconnects like CXL).\n\nExperience feeding golden models into a UVM/DV verification flow.\n\nModelling for mixed-signal or optical/SerDes systems, including control-loop / plant modelling.\n\nHigh-throughput datapath modelling.\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":3591,"description_truncated":false,"requirements":{"experience_years_min":8,"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":36,"band":"fade","label":"Fading","p_open":1,"p_active":0.81,"p_room":0.44,"age_days":120,"expected_fill_days":118,"reasons":["conf:2","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-23T05:54:15Z"},"pay":null,"html_url":"https://alion.io/job/lumilens-modelling-lead-systemc-virtual-platform-architect","json_url":"https://alion.io/job/lumilens-modelling-lead-systemc-virtual-platform-architect.json","meta":{"generated_at":"2026-10-23T05:59:06Z","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":9671,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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-modelling-lead-systemc-virtual-platform-architect"},{"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-modelling-lead-systemc-virtual-platform-architect"},{"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-modelling-lead-systemc-virtual-platform-architect"},{"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-modelling-lead-systemc-virtual-platform-architect\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flumilens-modelling-lead-systemc-virtual-platform-architect"}]}
