We're committed to bringing passion and customer focus to the business. At Lumentum, we’re building the tech behind the world’s fastest networks and most advanced systems. Our optical and photonic solutions power everything from AI and cloud computing to data centers, telecom, and advanced manufacturing. We’re a global team of innovators working where light meets technology, solving big challenges that keep the world connected and moving forward.

Principal Engineer: silicon photonics – Hybrid integration is a key leader responsible for the development of high-volume process flows that integrate unique materials to enhance the performance of Silicon photonics. The solutions will be deployed to cloud and network applications, for the rapidly growing AI market. You will work in a team environment to develop unique process flows and chip functionality through conception, process step design, process integration, plus the analysis and optimization of the integrated component performance.

Work collaboratively with wafer fabrication partners and back end of line process integration partners to ensure that the final chip solutions meet all end customer specifications, and the constraints for target applications considering fabrication process capability and required manufacturing tolerances. Collaborate with test engineering team to develop dedicated test and verification plans, define requirements, and analyze engineering verification measurements. Consider performance and specification margin to enable high yield in a cost-sensitive high-volume manufacturing setting.

Create a culture of continuous improvement to optimize performance and cost efficiency,
