Sr Staff Integrated Photonics Laser Systems Architect

Company Overview

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.

Job Overview

We are hiring a Senior Staff Laser Architect to join our Laser System Architecture & Engineering (LSAE) team. In this role, you will define the architecture of Guide™, Lightmatter's laser platform that supplies multi-wavelength optical power to photonic interconnects for AI infrastructure, and of Data-SOA, the semiconductor optical amplifier that boosts modulated data signals in the optical link.

Responsibilities

• Define and own the Guide laser architecture, from concept through high-volume production.
• Define and own the Data-SOA architecture in Lightmatter’s optical links.
• Deliver laser module architecture specifications and work closely with hardware and software teams to define functionality, interfaces, and documentation.
• Actively collaborate with Lightmatter Passage team to drive alignment between Guide and Passage product architectures.
• Engage in problem-solving to develop innovative high-performance laser solutions.
• Collaborate across disciplines with electronics, photonics, mechanical, and thermal engineering teams.
• Engage with engineering, product, sales, and architecture teams to define requirements for subsystems.
• Validate architectures, models, and specifications via hands-on testing.
• Collaborate with test engineers and technicians to define production test and validation protocols.
• Work with external vendors to ensure timely development and delivery of key processes and components.
• Contribute to the roadmap of laser development, improving performance, scalability, power consumption, and cost.
• Publish and present novel ideas, and participate in premier photonics conferences.

Required Qualifications

• PhD in Photonics, Electrical Engineering, Applied Physics, or a related technical field.
• 8+ years of hands-on experience in optical devices, PICs, and semiconductor physics.
• Expertise in mathematical modeling and simulation utilizing Python.
• Exceptional oral and written communication skills.
• Strong analytical problem-solving skills.
• Self-driven initiative with a collaborative mindset.

Preferred Qualifications

• Experience architecting lasers for datacom applications.
• Experience with semiconductor optical amplifiers in datacom links.
• Solid foundation in semiconductor laser physics.
• Experience with wavelength locking, thermal tuning, and power-control loops.
• Experience taking products into a high-volume manufacturing environment.
• Demonstrated technical leadership of a cross-functional team.
• Contributions to optical standards bodies, publications, and patents.
