Own strategic sourcing, supplier strategy, negotiations, cost optimization, supply continuity, and supplier performance for photonics products. Build and manage global supplier networks across silicon photonics, advanced packaging, optical components, contract manufacturing, and manufacturing partners. Partner with engineering, operations, manufacturing, and finance to support NPI, supplier qualification, capacity planning, risk mitigation, and transitions to high-volume manufacturing.

Lead development and optimization of wafer backside grinding, laser stealth dicing, and die sorting for silicon photonics. Troubleshoot process issues, improve yield and throughput, ensure compatibility with bumping/flip-chip, and produce SOPs, WIs, failure reports, and support NPI and process verification.

Develop and optimize optical alignment and assembly processes for photonic products from prototype through NPI and volume manufacturing. Responsibilities include active and passive alignment, epoxy dispensing and curing, equipment qualification, DOE, process characterization, statistical capability analysis, root-cause investigation, yield improvement, documentation, DFM/DFA support, and manufacturing transfer. The engineer will collaborate with R&D, manufacturing, suppliers, quality teams, and contract manufacturers to establish robust processes and production controls.

Manage external semiconductor foundry partnerships and coordinate technical, business, and production deliverables. Lead product transitions from NPI to high-volume manufacturing, improve on-time delivery and cycle time, and resolve yield, RMA, and process-excursion issues. Oversee root-cause analysis, corrective actions, quality metrics, process change notifications, fab audits, SPC, DOE, and FMEA activities while supporting process integration and production quality.

Own and improve wafer-level testing operations, including process development, qualification, production execution, process control, yield improvement, failure debugging, data analysis, documentation, and cycle-time optimization. Lead continuous improvement using DOE, SPC, Six Sigma, and root-cause analysis while collaborating with engineering, quality, supply chain, and manufacturing partners to support product qualification and production ramp.

Lead development, integration, optimization, and technical support for wafer bumping and Fan-Out processes used in silicon photonic chip wafers. Responsibilities include process pathfinding, materials qualification, reliability validation, failure analysis, yield improvement, SPC control, incoming wafer quality, and NPI documentation. The role requires hands-on advanced packaging experience and expertise in photolithography, deposition, electroplating, finite element analysis, DOE, FMEA, and analytical software.

Lead development of wafer-level opto-electrical test solutions for NPO/CPO products across NPI to volume production. Design and qualify test hardware and software, manage RFQ and vendor qualification, transfer testers to production, create process documentation and training, and provide ongoing engineering support to maintain yield, throughput, alignment stability, and reliability.

Lead cross-functional programs across silicon, photonics, packaging, bring-up, validation, and system delivery. Create and execute project plans, manage risks and schedules, coordinate vendors and partners, and communicate status to leadership to drive product readiness on aggressive timelines.

Drive end-to-end process development and manufacturing-readiness programs across photonics, advanced packaging, optical module assembly, and external manufacturing partners. Manage schedules from DOE and qualification through pilot builds and high-volume manufacturing release. Coordinate engineering, quality, operations, OSATs, suppliers, and manufacturing teams while ensuring process FMEA, DFM, audits, change control, reliability, and production requirements are met. Lead technical discussions, resolve risks, and make data-driven decisions during development and ramp-up.

Manage supplier quality relationships, define quality requirements, conduct audits, and improve supplier performance through structured reviews and corrective actions.

The Director of FP&A will lead financial planning, operational KPIs, and analysis for Lumilens, collaborating with R&D and business leaders to strengthen financial discipline in a fast-paced environment.

The Epoxy Engineer will develop and optimize epoxy formulations, troubleshoot adhesive failures, support manufacturing scale-up, ensure reliability, and provide global technical support.

The Silicon Test Engineer develops test solutions for silicon photonics and semiconductor products, optimizing test processes, collaborating with teams, and ensuring production readiness.

The Director/Sr. Director of Controlling leads corporate controllership across APAC, managing consolidations, statutory reporting, SOX compliance, and audit relations while partnering with finance and operations.

The Component Engineer is responsible for ensuring the quality, performance, and reliability of electronic components, supporting production and testing, coordinating with internal teams and vendors, and preparing technical documentation for products.

Lead development and support of flip chip assembly for silicon photonics, including DOE, material qualification, reliability validation, failure analysis, SPC, and NPI documentation to improve yield and manufacturability.

Develop and optimize optical active alignment processes for photonic transceiver production. Operate, control, qualify, and buy off alignment equipment; develop alignment algorithms; manage epoxy dispensing and curing; design alignment fixtures; troubleshoot production issues; and collaborate with R&D and manufacturing teams to improve yield, quality, documentation, and continuous improvement.

Own optical transceiver manufacturing readiness and product execution from development through high-volume production. Lead NPI, product transfers, contract manufacturer qualification, yield improvement, quality and reliability efforts, BOM accuracy, testing, failure analysis, corrective actions, documentation, and cost reduction. Collaborate with design, process engineering, quality, suppliers, and contract manufacturers to launch and scale 800G and 1.6T products. International travel is required.

Own end-to-end recruitment across technical, manufacturing, operations, and corporate roles in Singapore. Lead high-volume hiring campaigns, partner with contract manufacturers and business leaders, develop sourcing strategies, manage candidate experience and onboarding, monitor recruitment metrics, and advise leadership on workforce planning, talent availability, timelines, and hiring competitiveness. Coordinate across US and APAC time zones and support hiring initiatives at the Bulim Square facility.
