Xanadu’s mission is to build quantum computers that are practical and available to people everywhere. 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. We are looking for a hands-on, analytical, and driven Photonics Engineer to join our hardware team and accelerate the development of our Fault-Tolerant Quantum Computing (FTQC) systems.

If you thrive in a lab environment, love bridging the gap between physical hardware and mathematical modeling, and want to solve critical loss and performance challenges, we want to hear from you! You will rapidly onboard onto our proprietary testing frameworks, transition into independently running advanced characterization experiments, and ultimately leverage your insights to plan, order, and validate next-generation of devices. You will be the bridge between empirical lab data and the predictive models that drive our hardware roadmap.

Program custom Python scripts to automate lab testing, streamline data gathering, and process complex datasets independently. Utilize internal tools and python based frameworks to independently test, characterize, and benchmark incoming hardware. Translate baseline characterization data into actionable insights to help plan, specify, and order brand-new, optimized designs.

Build upon and refine our existing analytical and numerical models to unlock a deeper, company-wide understanding of the physical processes driving optical loss and system performance.



Propose innovative solutions to minimize loss, test them rigorously in the lab, and validate performance improvements on your own custom-planned designs.

Environmental Mitigation: Factor critical real-world variables—specifically thermal management and vibration isolation—into experimental setups to protect sensitive optical performance.

Environmental Physics: Clear understanding of thermal management and vibration dynamics, including how these environmental factors impact optical system stability.

Programming Aptitude: Basic proficiency in Python programming, with a strong willingness and aptitude to quickly learn lab automation and instrument control.

Technical Adaptability: A Bachelor’s or Master’s degree in Physics, Photonics, Optical Engineering, Electrical Engineering, or a related technical discipline. A self-starter mindset with a proven track record of gathering, processing, and drawing conclusions from data independently to push a project forward. The base salary range is 110,000 - 140,000 CAD.

You will also be eligible for equity and benefits. They are fundamental and lay the foundation for culture 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.

We are committed to meeting the needs of all individuals and support a barrier-free workplace. Please be advised that we may use artificial intelligence (AI) tools to assist in the screening and assessment of applicants for this position.
