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. At Lumilens, we’re developing high-speed photonics products purpose-built to power the future of AI infrastructure and high-performance computing. \nThis isn’t incremental innovation, it’s a ground-floor opportunity to rethink the optical layer from the silicon up. You’ll work alongside a team of world-class engineers solving some of the hardest challenges in scaling optical systems. If you're looking for mission, momentum, and the chance to make an outsized impact, jump on the rocket ship. We’re just getting started.\nRole Overview\nWe are seeking a detail-oriented Material Planner to execute day-to-day material planning and procurement activities that keep prototype, pilot, and production builds on schedule. This role owns the tactical, hands-on work of running MRP, placing and tracking purchase orders, monitoring supplier deliveries, and flagging shortages - turning the material plans set by the Planning Manager into concrete, on-time execution. This is an execution-focused role, distinct from the Planning Manager, who owns overall material strategy and cross-functional planning.\nKey Responsibilities\nMaterial Planning & Execution\nRun MRP and translate net requirements into purchase orders and supplier releases.\n\nPlace, track, and expedite purchase orders to ensure on-time delivery against build schedules.\n\nMonitor open PO status daily, following up directly with suppliers/CM partners on delayed or at-risk shipments.\n\nMaintain accurate system data for lead times, order quantities, safety stock levels, and delivery dates.\n\nInventory Management\nMonitor daily inventory levels against safety stock and consumption plans.\n\nFlag excess, aging, or at-risk (expiring/obsolete) inventory to the Planning Manager.\n\nSupport cycle counts and inventory accuracy reconciliation.\n\nShortage & Exception Management\nIdentify and escalate material shortages that put build schedules at risk.\n\nCoordinate with suppliers and CM partners to resolve delivery exceptions and expedite critical shipments.\n\nMaintain a shortage/exception tracker and provide daily/weekly status updates.\n\nCross-Functional Support\nWork with the Planning Manager to align material orders with updated build plans and forecasts.\n\nSupport engineering change implementation by updating orders/quantities affected by BOM changes.\n\nCoordinate with logistics/warehouse teams on receiving, inspection, and staging of incoming materials.\n\nReporting\nMaintain PO tracker and delivery status reports for build readiness reviews.\n\nReport on delivery, shortage, and inventory metrics to the Planning Manager.\n\nQualifications\n2+ years of experience and a bachelor’s degree in engineering, business, supply chain, or a related field.\n\nStrong knowledge of materials planning fundamentals, including master data management, order policy, bill of material control, planning release, and fulfillment execution.\n\nProficiency with MRP and ERP systems used to support complex manufacturing and supply planning processes.\n\nStrong analytical skills with proficiency in Microsoft Office, mathematics, and statistics.\n\nExcellent verbal and written communication skills and a collaborative, team-oriented approach in a fast-paced environment.","description_format":"text","description_chars":3635,"description_truncated":false,"requirements":{"experience_years_min":2,"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":["Servers
