Director, Software Manufacturing

Director, Software Manufacturing LocationSan JoseEmployment TypeFull timeDepartmentEngineeringAbout LumilensAt Lumilens we are building the critical photonics infrastructure that powers tomorrow’s AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing, faster, cooler, and massively more efficient.We’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. This 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 optics, systems, and scale. 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.Position OverviewLumilens is seeking a Director of Software Manufacturing to lead the strategy, development, and execution of software systems that enable high-volume manufacturing of next-generation optical transceivers (800G, 1.6T and beyond). This role is responsible for building and scaling the software infrastructure that drives yield, test, calibration, and production efficiency across our photonics manufacturing ecosystem.This is a critical leadership role at the intersection of software, manufacturing, and hardware systems. You will define and implement manufacturing software frameworks that support end-to-end production—from wafer-level test and module assembly to final system validation—ensuring high yield, reliability, and throughput at scale.The ideal candidate brings deep experience in manufacturing software, test automation, and production systems within semiconductor, optical transceivers, or high-performance hardware environments, along with a strong track record supporting hyperscale customer deployments.Key ResponsibilitiesManufacturing Software Strategy & ExecutionDefine and lead the software roadmap for manufacturing systems supporting optical transceivers and photonic devicesArchitect scalable test, calibration, and data infrastructure for NPI and high-volume manufacturing (HVM)Drive software solutions for wafer probe, module test, system-level validation, and final testEnsure seamless integration between manufacturing software, MES systems, and factory automation platformsYield, Test & Production OptimizationDevelop software frameworks to improve yield, throughput, and cycle time across manufacturing linesLead implementation of data-driven yield analysis, failure detection, and root cause methodologiesBuild and deploy automated test and calibration systems for optical modules, including DSP tuning and optical alignmentPartner with manufacturing and quality teams to reduce escapes, improve reliability, and optimize costHyperscaler & Production ReadinessEnsure manufacturing software meets the scale, quality, and traceability requirements of hyperscale customersSupport customer qualifications, audits, and production ramp readinessImplement robust telemetry, logging, and traceability systems across the manufacturing lifecycleDrive alignment between internal manufacturing systems and customer validation environmentsCross-Functional LeadershipPartner closely with photonics, ASIC, hardware, systems, and operations teams to enable manufacturable product designsSupport NPI → HVM transitions with robust, production-ready software systemsInterface with foundries, OSATs, and contract manufacturers to standardize test and software infrastructureCollaborate with supply chain and operations to ensure capacity and scalabilityOrganizational Leadership & Team BuildingBuild, lead, and scale a high-performing software manufacturing and test engineering teamEstablish best practices in software development, release management, and manufacturing deploymentDrive a culture of operational excellence, accountability, and continuous...
