Lightmatter builds chips for artificial intelligence computing that leverage unique properties of light for efficient computing and communications. If you're a collaborative engineering leader who has a passion for innovation, solving challenging technical problems, and doing impactful work...work like building the world's first optical computers and developing high-speed silicon photonics-based optical interconnect solutions, consider joining the team at Lightmatter!

We are hiring a Director of Engineering for our Laser Development Team. The selected candidate will partner with our Architecture Group, Packaging Team, and a dedicated team of laser engineers to deliver designs aligned to the requirements of our new generation of Passage photonic-based communication fabric products from definition through design, lab test, characterization, qualification, and volume product release. In this high-impact role, you will work closely with our Architecture, Photonic, Analog, and Packaging teams to define and optimize the design features needed to improve the power, performance, and area (PPA) of our laser solutions. This will require a solid understanding of silicon photonics platforms and process technology, state-of-the-art laser design, component-level design, physical design, and laser modeling as well as clear technical documentation and communication skills. We are particularly looking for someone with hands-on expertise in semiconductor optical amplifier technology, laser cavity design, and gain materials.

Join a tight-knit team where each individual’s contributions directly influence the success of the product and the company. You'll have the opportunity to build a new kind of computer and photonic interconnect solutions 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.
