Principal Member of Technical Staff, LCM Advanced Packaging & Manufacturing Engineer
Lumotive is pioneering the era of programmable optics—where light is controlled as intelligently and flexibly as software.
At the heart of this transformation is a once-in-a-generation innovation: a flat CMOS-based “general purpose optic.” Lumotive’s Light Control Metasurface (LCM™) beam forming chips can be programmed to function as a beam steering mirror, a lens, mirror, a beam splitter—or any optical function—replacing bulky and mechanical optical components with a fully digital, reconfigurable semiconductor . This breakthrough lays the foundation for a massive shift in multiple technologies—from 3D sensing and imaging to optical networking, free space optical communication, and beyond. Like the shift from analog to digital in electronics, programmable optics will reshape industries from robotics, self-driving cars, AI, defense, and healthcare.
Lumotive’s first commercial application is in LiDAR, where its software-defined beam steering chips are already enabling compact, high-performance, solid-state sensors. These sensors are being deployed today in smart infrastructure, robotics, and mobility systems through leading module makers and solution integrators.
With more than 200 patents and growing commercial traction, Lumotive is delivering the world’s first digital platform for light—and redefining what’s possible in the optical age.
Job Description: Lumotive is seeking a Principal Member of Technical Staff based in Taiwan with deep expertise in New Product Introduction (NPI) and production management for semiconductor advanced packaging and test of optical devices. This is an outward-facing role that requires regular travel to key suppliers across Taiwan and China. You will serve as a critical link between design and production, executing best practices with vendors across wafer fab, OSAT, LCOS assembly, optical sub-assembly, and test, including support for Lumotive’s wafer fab partner as needed. In addition to technical leadership, this role requires strong project ownership, supplier coordination, and disciplined execution to drive schedules, milestones, and issue resolution across a distributed supply base. The role reports to the Director, Semiconductor Module Manufacturing in the Redmond, Washington office.
Responsibilities: Supplier Engagement & Project Management
Own technical engagement and production support with OSATs, LCOS assembly, optical sub-assembly and test vendors, and wafer fab partners
Drive supplier project plans, schedules, deliverables, and risk mitigation to ensure on-time execution
Travel 50% of time to supplier sites across Taiwan and China to ensure alignment, troubleshoot issues, and remove execution barriers
Support customer fulfillment while helping define and implement long-term volume ramp strategy
Coordinate cross-functional escalation and decision-making between internal teams and suppliers to keep NPI and production activities on track
NPI & Technical Execution
Lead NPI assembly process development for LCM-based optical modules, transitioning from low-volume builds to scalable production
Define, develop, and qualify advanced packaging architectures (e.g., flip-chip, wafer-level assembly, fan-out, CoC using ACF, TCB, LAB)
Collect, consolidate, and communicate Design for Manufacturability (DFM) feedback from suppliers
Serve as the on-site production test interface between Taiwan suppliers and Lumotive’s in-house test team; provide Level 1 troubleshooting support, triage hardware/software interactions, and escalate issues with clear documentation
Guide suppliers and the Lumotive test team on manufacturing test best practices for a production environment, including test coverage strategy, yield tracking, and test station readiness criteria
Provide inspection and failure analysis (FA) feedback to drive supplier corrective actions for prototype and production builds
Establish build readiness criteria and support qualification activities for new processes, tooling, and suppliers
Documentation, Quality & Continuous Improvement
Contribute to design reviews and Technical Data Package creation
Apply configuration management and quality best practices internally and with suppliers for change management, RMA, SCAR, CAPPA, and related workflows
Develop and maintain assembly instructions, inspection plans, SOPs, and manufacturing documentation
Drive yield improvement, process optimization, and cost reduction across the supply chain
Monitor supplier readiness, process capability, and production risk to support successful product ramps
Own production test environments; provide Level 1 troubleshooting, support hardware/software interactions at the test station, and act as an effective on-site liaison with Lumotive’s test engineering team
Qualifications: Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Materials Science, or a related field (MS/PhD or equivalent practical experience strongly preferred)
12+ years of industry experience, including 10+ years in supplier-facing manufacturing, process, quality, or NPI engineering roles
Fluency in Mandarin and English is required
Proven experience in DFM and process design for opto-mechanical and opto-electronic systems
Strong background in semiconductor packaging, LCOS, or MEMS assembly, with a focus on optical subsystems
Experience working with semiconductor and advanced packaging suppliers in Taiwan
Demonstrated ability to manage complex project schedules and drive supplier execution
Experience with wafer bonding, dicing, AOI, wire bonding, optical alignment, and related assembly processes
Skilled in drawing review, process documentation, technical data packages, and production audits
Experience leading supplier qualification, process readiness reviews, and production ramp activities
Ability to drive technical issue resolution across design, test, quality, and operations teams
Experience with PLM, MES, and SPC systems for managing production data and supplier quality is required
Experience with tools such as Arena (PLM), SolidWorks, Tableau, and JMP
