Principal Laser Architect

Laser Architect

Lightmatter builds chips for artificial intelligence computing that leverage unique properties of light for efficient computing and communications. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems, and doing impactful work...work like building the world's first optical computers, consider joining the team at Lightmatter!

We are hiring a Principal Laser Architect. The selected candidate will partner with external facing teams at Lightmatter and the internal engineering team to deliver groundbreaking products to the market. As a laser architect, you will design laser systems and provide detailed technical documents that describe our lasers. This will require a solid understanding of process technology, state-of-the-art laser design, and clear communication skills. You will represent the company externally at technical conferences as an example of our technical leadership.

We seek a motivated and dedicated hands-on Laser Architect to help develop next-generation lasers for our ground-breaking optical communication fabric alongside a team of world-class scientists and engineers. In this role, you will define the laser architecture for a photonic-based communication fabric. From component-level design to top-level layout, you will be part of a team that enables high-bandwidth, low-latency photonic interconnect/switch fabric.

This is a high-visibility role. You will also work closely with our photonic, analog, and packaging teams to define and optimize the features needed to improve the power, performance, and area (PPA) of the next-generation product. We are particularly looking for someone with expertise in laser cavity design, gain materials, and semiconductor optical amplifier technology.

Join a tight-knit team where each individual’s contributions directly influence the success of the company and product. You'll have the opportunity to build a new kind of computer from the ground up and to solve groundbreaking challenges along the way. Work with people who love to build and who thrive in technically diverse environments where great ideas are prioritized.
