Photonics Design and Layout Engineer

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!

If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders.

Lightmatter is (re)inventing the future of computing with light!

About this Role

We are hiring a Staff Photonics Design and Layout Engineer to join our rapidly growing team. In this role, you will be working closely with photonics, product, architecture, analog, digital and packaging teams to floorplan, design and layout block- and chip-scale photonic circuits. You will be tasked with supporting photonic products throughout their entire development cycle, from a clean sheet concept all the way to the tapeout and bring-up. Leveraging our industry-leading and proprietary photonics integration and verification flow and tools, you will be working on verifying that all blocks and circuits meet their performance design targets.

Join a tight-knit team where each individual’s contributions directly influence the success of the company and product. You'll have the opportunity to build innovative integrated photonic solutions from the ground up and tackle groundbreaking challenges. Work with people who love to build and who thrive in diverse technical environments where great ideas are prioritized.

Responsibilities

• Understand product requirements and work with customer-facing teams to help identify optimal photonics solutions
• Work on clean sheet design and layout of block- and system-level photonic circuits 
• Work with analog, digital and packaging teams to ensure seamless integration of on-chip photonics with other subsystems
• Perform rigorous layout-driven photonic simulation and verification. Identify performance bottlenecks and troubleshoot issues.
• Help develop and improve photonic layout, verification and integration flows for multiple photonic processes and foundries
• Contribute to proprietary PDK development
• Engage in problem solving and contribute to new photonic chip designs and architectures.
• Publish novel results, and participate in premier optics/photonics conferences.

Qualifications

• MS + 10 years or PhD + 3 years of industry experience in Electrical Engineering, Physics, Photonics, or related discipline
