Mechanical Design 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!

In this role, you will be working on leading-edge packaging technologies to enable AI architectures that set new industry standards for compute power, performance, and efficiency. As a member of the Packaging team, you will collaborate with several teams to identify key failure modes under product use conditions and run appropriate parametric design studies to influence product and package design upstream. You will be responsible for the package stack-up analysis, co-optimizing mechanical, optical and thermal aspects that influence package form factors, and driving socket/enabling mechanisms. You will utilize Geometric Dimensioning and Tolerancing (GD&T) to propose solutions that finalize the design. Your work will result in advanced package designs that meet power dissipation, assembly, optical, and reliability requirements, while delivering a system level solution for leading edge products in the data centers and high-end compute segment.

Responsibilities:

• Create CAD models of package stack-up and associated components.

• Perform mechanical design anal
