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 industry leaders.

Lightmatter is (re)inventing the future of computing with light!

About This Role

We are hiring a Photonics Architect. The selected candidate will partner with external facing teams at Lightmatter and internal engineering teams to deliver groundbreaking products to the market. In this role, you will design and develop innovative photonics architecture solutions to deliver high-volume products for our customers. You will engage with our cross-disciplinary engineering teams to model and analyze solutions. You may also test and measure prototypes to validate the models. This role requires a deep understanding of silicon photonics process technologies, state-of-the-art photonics designs, high-speed (40+ GHz) electro-optic interfaces, lasers, and 3D integration. The role also requires creativity, analytical skills, and clear communication skills. You may represent the company externally at technical conferences as an example of our technical leadership.

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.

Responsibilities

• Creative problem-solving and contributing to high-performance photonic architecture solutions for high-volume products.
• Develop specifications for passive photonic components, such as wavelength filters and polarization management components.
• Develop, simulate, and validate control and initialization algorithms for photonic circuits.
• Perform multiphysics considerations and simulations of photonic circuits.
• Validate the models by designing experiments, conducting proof-of-concept experiments, and analyzing data.
• Actively collaborate across disciplines—with electronics, photonics, and mechanical engineers—to design systems, algorithms, circuits, and devices that meet performance, power, and production requirements.
• Document and present your contributions.

This is not a complete listing of the responsibilities. It’s a representation of the things you will be doing.

Qualifications
