Lightmatter is a photonic computer company redefining what computers and human beings are capable of by building the engines that will power discoveries and drive progress in a sustainable way. With modern human progress relying heavily on computers, the world has hit a dead end with traditional transistors and the prospect of constantly building data centers is an environmental nightmare. Lightmatter has created a solution in photonic computing: using photons instead of electrons to take advantage of their higher bandwidth. We build chips for artificial intelligence computing. Our architecture leverages unique properties of light to enable fast and efficient inference and training engines.

Founded and headquartered in Boston, MA, Lightmatter also has an office in the California Bay Area to be close to the top tech talent. Lighmatter has grown to more than 80 employees and has raised over $100 million in funding from backers like Google Ventures, Matrix Partners, Spark Capital, and Viking Global.

We are hiring a Digital Design Engineer to help develop an ASIC for the next-generation artificial intelligence computing architecture alongside a team of world-class scientists and engineers. If your passion is on innovation, solving challenging technical problems and doing impactful work you should join our team and help building the world's first optical computers!
