Original job description

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:

In this role you will help develop the numerical toolkit for fault-tolerant photonic quantum computing architectures. Improvements to the scalability and performance of the architectures can enter anywhere in the stack, requiring a broad understanding of Xanadu’s public architecture and its iterations, but the focus will be on the logical (quantum error-correction) layers. Although you can expect some analytical work at various levels of abstraction, from optical circuits to qubit quantum error correction, the focus will be on the development of our in-house software tools. This will involve using, maintaining, optimizing, and introducing new features to the existing fault-tolerant software stack to run large-scale error-correction simulations for the purpose of evaluating performance and estimating resources.

Basic qualifications and experience:

MSc. in Physics, Mathematics, Computer Science, or Engineering, especially in topics relevant to quantum information theory
Several years of research or industry experience in related fields
Strong experience with object-oriented programming in Python
Experience with high-performance computing, including writing and running optimized and parallelized code on supercomputers and computing clusters
Experience with software engineering best practices: testing, continuous integration, version control, documentation, and code review
Familiarity with quantum computation theory, including quantum error correction under various noise models, codes, and decoders
Familiarity with the optical platform for quantum computation, especially bosonic codes such as GKP states and the continuous-variable formalism
Great communication skills, and the ability to clearly express complex technical concepts

Preferred qualifications and experience:

Up-to-date knowledge of the latest developments in quantum computing and error-correction
Some knowledge of measurement-based quantum computation
Some experience programming in low-level languages (e.g., C, C++)
Familiarity with and experience working in a fast-growing technology start-up environment
PhD in Computer Science, Physics, Mathematics, or Engineering is an asset

This is for a new position. Your base salary will be determined based on your location, experience, and internal benchmarks. The base salary range is 120,000 - 150,000 CAD. You will also be eligible for equity and benefits.

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

We are an equal opportunity employer and encourage candidates of all backgrounds to apply. 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. Should you require accommodations at any point during the recruitment process please contact Recruiting at recruiting@xanadu.ai.

Please be advised that we may use artificial intelligence (AI) tools to assist in the screening and assessment of applicants for this position. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.
