Lumilens is building photonics infrastructure for AI supercomputing, focusing on chip-to-chip optical interconnects and scalable photonic engines. The company is Series B-funded by Mayfield and led by technology veterans.
As Senior Director of Manufacturing Software Engineering, you will lead strategy, development, and execution of software systems enabling high-volume manufacturing of next-generation optical transceivers (800G, 1.6T, and beyond). This is a critical leadership role at the intersection of software, manufacturing, and hardware systems.
Key responsibilities include:
**Manufacturing Software Strategy & Execution**: Define and lead the software roadmap for manufacturing systems supporting optical transceivers and photonic devices. Architect scalable test, calibration, and data infrastructure for new product introduction (NPI) and high-volume manufacturing (HVM). Drive software solutions for wafer probe, module test, system-level validation, and final test. Ensure seamless integration with MES systems and factory automation platforms.
**Yield, Test & Production Optimization**: Develop software frameworks to improve yield, throughput, and cycle time across manufacturing lines. Lead implementation of data-driven yield analysis, failure detection, and root cause methodologies. Build and deploy automated test and calibration systems for optical modules, including DSP tuning and optical alignment. Partner with manufacturing and quality teams to reduce escapes, improve reliability, and optimize cost.
**Hyperscaler & Production Readiness**: Ensure manufacturing software meets the scale, quality, and traceability requirements of hyperscale customers. Support customer qualifications, audits, and production ramp readiness. Implement robust telemetry, logging, and traceability systems. Drive alignment between internal manufacturing systems and customer validation environments.
**Cross-Functional Leadership**: Partner closely with photonics, ASIC, hardware, systems, and operations teams to enable manufacturable product designs. Support NPI to HVM transitions with robust, production-ready software systems. Interface with foundries, OSATs, and contract manufacturers to standardize test and software infrastructure. Collaborate with supply chain and operations to ensure capacity and scalability.
**Organizational Leadership & Team Building**: Build, lead, and scale a high-performing software manufacturing and test engineering team. Establish best practices in software development, release management, and manufacturing deployment. Drive a culture of operational excellence, accountability, and continuous improvement. Mentor engineers across software, test, and manufacturing domains.
Required qualifications: Bachelor's or advanced degree in Electrical Engineering, Computer Engineering, Computer Science, or related field. 15+ years of software engineering experience with significant focus on manufacturing, test, or production systems. 5+ years of leadership experience managing engineering teams. Strong background in manufacturing software, test automation, and production systems for semiconductor, photonics, or hardware products. Proven experience supporting NPI to HVM, including yield ramp and production scaling. Experience working with contract manufacturers, OSATs, and/or global manufacturing partners. Strong programming experience (Python, C/C++, or similar) for automation, test, and data systems. Deep understanding of manufacturing KPIs: yield, throughput, cycle time, cost, and quality. Experience with MES systems, data pipelines, and manufacturing analytics.
Preferred qualifications include experience with optical transceivers (QSFP, QSFP-DD, OSFP) and high-speed modules (400G, 800G, 1.6T), silicon photonics, advanced packaging, optical module manufacturing, factory automation systems, DSP-based systems, and experience supporting hyperscalers or Tier 1 data center customers.
