Lightmatter is building the world's first 3D-stacked photonics engine (Passage™) to enable extreme-scale AI and HPC data centers. The company recently raised $400M in Series D funding at a $4.4B valuation and is accelerating development across all departments.
As a Photonics Architect, you will define the micro-architecture for a groundbreaking photonic-based communication fabric, working from component-level design through top-level layout. You will partner closely with the internal engineering team to deliver innovative photonic products to market, providing detailed technical specifications and architectural documentation.
Reporting directly to the Sr. Director of Architecture, you will collaborate extensively with photonic and analog engineering teams to optimize power, performance, and area (PPA) metrics for next-generation products. Your work will directly influence the success of the company and product in a tight-knit, technically diverse environment.
Key responsibilities include:
- Proposing innovative photonic designs (modulators, receivers, multiplexers, lasers, amplifiers) for the product
- Providing performance, power, and area estimates for photonic devices within Passage
- Collaborating with analog engineering teams to deliver high-bandwidth photonic interconnect solutions
- Authoring, reviewing, and validating architectural specifications
Qualifications:
- PhD in electrical engineering, physics, applied physics, or related photonics discipline
- In-depth knowledge of photonic devices and semiconductor physics
- Experience with integrated silicon photonics components
- Preferably experience with photonic simulation tools (FDTD, Lumerical, Verilog-A, VPI Photonics)
- Strong ability to collaborate across disciplinary teams
- Demonstrated problem-solving skills for complex, non-obvious technical challenges
