HRL is a world-leader in silicon quantum dot technologies. At HRL, we are developing a full quantum device and computation stack, including an optimizing compiler for a quantum programming language. As a Principal Software Engineer within the Quantum Programming group, you will be a core contributor to this stack, including both maintenance and significant new feature development. Our compilers are primarily written in Common Lisp, and interface with a lot of software, both as a library and as a stand-alone application. In addition to technical work, you will have leadership responsibilities, helping shape the direction of compiler and programming language development activities at HRL.
