Sr. Simulation Hardware/Software Engineer

Lightmatter is at the forefront of revolutionizing AI data center infrastructure, having invented the world's first 3D-stacked photonics engine, Passage™. This groundbreaking 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 Sr. Simulation Hardware/Software Engineer at Lightmatter, you'll be part of a team that's (re)inventing the future of computing with light. You'll work on developing and maintaining simulation tools across digital, analog, and photonics domains, collaborating closely with cross-functional teams to deliver groundbreaking products to the market.

Your responsibilities will include developing electro-optic simulation methodologies, working with various simulators (Xcelium, Spectre, scattering parameter simulators), and programming in languages like SystemVerilog, VerilogA, and Python. You'll be instrumental in architecting digital circuits to enable high-speed AMS circuits, with a focus on photonic circuits.

This role offers the unique opportunity to build a new kind of (super)computer from the ground up, solving groundbreaking challenges along the way. You'll be part of a tight-knit team where your contributions directly influence the company's success, working alongside people who love to build and thrive in technically diverse environments.

Lightmatter recently raised $400 million in its Series D round, reaching a valuation of $4.4 billion, which demonstrates the company's strong growth trajectory and the potential for significant impact in the field of AI and computing.

Join Lightmatter if you're passionate about tackling complex challenges, making a real impact, and being an expert in your craft. You'll be working with a team of brilliant scientists, engineers, and accomplished industry leaders, all dedicated to enabling the next giant leaps in human progress through revolutionary computing technology.
