Lightmatter Sr. Power Methodology Engineer (Boston) in Boston, Massachusetts

Power Methodology Engineer

Lightmatter is a photonic computer company that is redefining what computers and human beings are capable of by building the engines that will drive discoveries and progress sustainably. 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 builds chips for artificial intelligence computing. Our architecture leverages the unique properties of light to enable a fast and efficient compute platform. We created a solution in photonic computing: using photons instead of electrons to take advantage of their higher bandwidth.
