Photonics Technical Lead

Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world’s first 3D-stacked photonics engine, Passage™, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads. Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter! We are hiring a Photonics Technical Lead to join our laser development team. In this role, you will develop integrated and highly scalable laser solutions for silicon photonics AI communications and computation. You will work closely with cross-disciplinary engineering teams both internally and across our ecosystem of manufacturing partners to assess the technical feasibility of product requirements, develop an engineering plan to meet architectural specifications, execute new product designs for laser solutions, and validate system performance on hardware. Responsibilities

Engage with a cross-functional team to design and deliver a successful high-volume laser product Collaborate with product and architecture teams to drive new laser concepts Work closely with hardware and software teams to translate high level laser module product requirements and architecture specifications into a detailed engineering execution plan Engage in problem-solving to resolve design and manufacturing challenges for innovative high-performance laser solutions Actively collaborate across disciplines—with electronics, photonics, mechanical, thermal and package-design engineering teams—to build laser systems, control algorithms, PICs, and control ASICs that meet performance, power, and production requirements Collaborate with control-system and test engineers to define production test and validation protocols, as well as to characterize components and debug test results from prototype level to validation Work with external vendors to ensure timely development and delivery of key processes and components Requirements

A Ph.D. in Photonics, Electrical Engineering, Applied Physics, or a related discipline, with at least 3 years of relevant post-degree experience (or equivalent). A minimum of 8 years of experience in photonic devices, photonic integrated circuits, and semiconductor physics. Strong understanding of silicon photonics Experience of closely collaborating with cross-functional engineering teams, like photonics design, packaging, thermal, system engineering and firmware to name a few. Ability to convey complex technical concepts to both technical and non-technical stakeholders with strong and clear communication Demonstrated strong problem solving skills specifically pertaining to problems that do not have obvious solutions Preferred Qualifications

Strong understanding of laser physics Experience in lasers or silicon photonics for datacom applications Experience with control systems and system engineering Experience working in a high volume manufacturing environment Demonstrated technical leadership of a cross-functional team Willing and able to learn quickly, self-starter with a "no task is too big or small" attitude Benefits & Compensation
