Posted on May 14, 2025

About Xanadu:

Xanadu’s mission is to build quantum computers that are useful and available to people everywhere.

At Xanadu, we are learners, innovators, researchers, collaborators and problem solvers. We are creating something that has never been built before. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems, and literally change the world. And that is something to be excited about!

Your role and responsibilities:

Based within the Fault Tolerant Quantum Computing Devices team, you will be working to develop and deploy the hardware required for our integrated photonic quantum computation platform. In the role of photonic engineer (low noise laser systems), you will be designing and building a new low noise laser system and using it to test new generations of our squeezed light sources. You’ll also work with internal and external engineering teams to capture and define requirements for Xanadu’s next generation of low noise lasers. The chosen candidate will have a proven track record of accomplishments in photonics research and development with an industrial mindset.

Basic qualifications and experience:

  • PhD in photonics, AMO, or related discipline
  • Academic or industrial experience in photonic engineering, specifically working with low noise/phase locked/injection locked lasers
  • Strong understanding of photonics and electronics
  • Self-motivated and comfortable working in a fast-paced team environment

Preferred qualifications and experience:

  • A solid understanding of narrow-linewidth lasers, phase stable frequency combs, optical interferometers and high-bandwidth control loops (PLLs, Pound-Drever-Hall etc.)
  • understanding of coherent detection (homodyne/heterodyne), phase-sensitive experiments, and shot noise-limited measurement
  • Experience with RF electro-optic tools and techniques (EOMs, IQ modulators, etc.)

Our values are important. They are fundamental and lay the foundation for culture at Xanadu. Learn more about our values here.

At Xanadu, we are committed to building an inclusive, safe, and equitable culture and fostering an environment where our employees feel included, valued, and heard.
