Staff Analog/Mixed-Signal IC Design Engineer (US)

High Speed Analog Design EngineerLightmatter builds chips that enable extreme-scale artificial intelligence computing clusters. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems, and doing impactful work like building the world's first optical computers, consider joining the team at Lightmatter!In this role, you will be a key member of the analog team architecting the world's first photonic computers. This is fundamentally an interdisciplinary team, and outside-the-box thinking is the daily norm. You will need both deep expertise in mixed-signal and analog design and breadth across other engineering disciplines, such as photonics and digital electronics, semiconductor device physics, thermal/packaging, and machine learning. The successful candidate will demonstrate an eagerness to refresh and grow their competency in these areas.*We are currently hiring for multiple levels for this role. Your level and compensation will be determined by your experience, education, and location.Responsibilities
