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. What we are doing is extremely hard, the classic moon shot. 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

• Design, build, deploy, and maintain the tooling that is internally used by hardware researchers.
• Design APIs and full-stack web-delivered services for consumption by internal and external stakeholders.
• Manage cloud-backed data infrastructure (AWS) that stores, processes, and serves results to the broader hardware organization.
• Work alongside researchers to translate their research and engineering needs into high-quality software solutions
• Ensure production-quality code by maintaining automated test coverage, CI/CD pipelines (GitHub Actions, Docker), and a dynamic code review process.
• Own a significant part of the domain, exploring and advocating for new technologies.
• Perform DevOps tasks, including maintaining build and deployment pipelines, containerized environments, and release strategies across multiple repositories.

Basic Qualifications And Experience

• BSc in Computer Science, Engineering, Physics, Math, or a related field.
• Years of Experience:
• Intermediate: 3+ years of professional software development experience.
• Senior: 7+ years of professional software development experience.
• Strong knowledge of modern development languages (Python, Go, or Rust).
• Proficient in PostgreSQL and SQL optimization.
• Familiar with developing and interfacing with API endpoints.
• Experience using Docker, Infrastructure as Code, and deploying to cloud providers like AWS or Google Cloud.
• Strong communication and collaboration skills - ability to work closely with hardware engineers and scientists and translate their needs into software solutions.
• A desire to learn the fundamentals of a new domain (e.g., photonics, chip fabrication, hardware architecture) in order to build effective tooling.

Preferred Qualifications And Experience

• Experience with AWS services (S3, DynamoDB, Lambda, ECS, API Gateway).
• Experience with Rust.
• Experience with simulation or EDA tooling for integrated photonics or chip design (e.g., IPKISS, GDSFactory, KLayout).
• Experience with optical or electromagnetic simulation tools (e.g., FDTD, Eigenmode Expansion, Finite Element Methods).
• Experience with scientific/numerical Python libraries (NumPy, SciPy, pandas, xarray).
• Experience with Docker and containerized development environments (Docker Compose, multi-architecture builds).
• Experience managing complex branching and release strategies across interdependent repositories.
• Familiarity with Jupyter notebook-based workflows for engineering teams.

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 100,000 - 140,000 CAD for intermediate candidates and 150,000 - 190,000 CAD for senior candidates. You will also be eligible for equity and benefits.
