Senior Analog/Mixed-Signal Design Engineer

Lightmatter is at the forefront of revolutionizing AI data center infrastructure with their groundbreaking invention: the world's first 3D-stacked photonics engine, Passage™. This innovative technology enables the connection of thousands to millions of processors at the speed of light in extreme-scale data centers, catering to the most advanced AI and HPC workloads.

As a key member of the analog team, you'll be instrumental in architecting the world's first photonic computers. This role demands a unique blend of deep expertise in mixed-signal and analog design, coupled with a broad understanding of related disciplines such as photonics, digital electronics, semiconductor device physics, thermal/packaging, and machine learning.

Your responsibilities will include supporting micro-architecture development, collaborating with various design engineering teams, designing analog/mixed-signal blocks (focusing on transceivers), documenting designs, driving block-level floorplans, running simulations, and validating circuit performance in the lab.

The ideal candidate will have a strong background in optical or wireline transceiver design, with experience in designing Analog-Front-End blocks, Tx/Rx equalization techniques, and SERDES architectures. Familiarity with Cadence Design Environment and 3D Electro-Magnetic simulation tools is highly valued.

Joining Lightmatter means being part of a team of brilliant scientists, engineers, and industry leaders who are tackling complex challenges and making a significant impact. With a recent $400 million Series D funding round and a $4.4 billion valuation, Lightmatter is poised for continued growth and innovation in data center photonics.

The company offers a competitive salary range of $130,000 to $240,000 USD, along with comprehensive benefits including health care, retirement savings matching, generous time off, and stock options. Lightmatter promotes a flexible, hybrid workplace model and is committed to diversity and inclusion in its hiring practices.
