Original job description

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!

We are hiring a Digital Design Engineer to help develop an ASIC for the next-generation artificial intelligence computing architecture alongside a team of world-class scientists and engineers. If your passion is innovation, solving challenging technical problems, and doing impactful work, you should join our team and help build the world's first optical computers!

Responsibilities

Develop RTL (i.e. system Verilog) modules with DFT considerations for IC development
Debug complex logic and mixed signal simulations
Understand and integrate silicon photonic communication and compute technology into digital accelerator design
Actively work with Architecture, Design Verification, Physical Design, Photonic, Analog and Software teams to realize high performance, low power designs in advanced technology nodes
Create design specifications and documentation to facilitate collaboration with partner teams
Generate documentation for modules, including functionality and timing
Manage RTL implementation to achieve functionally correct, performant designs within project schedules by identifying, communicating and mitigating risks.
