Full Job Description
Your role and responsibilities:

As a Software Developer, you will contribute to the platform and infrastructure that powers Xanadu's quantum hardware development. You will work alongside hardware architects, photonic engineers, scientists, and data analysts - building the tools and services that accelerate the design, simulation, fabrication, and operation of our quantum hardware. As a result, you will completely reshape the nature of computation as we know it. You will have the opportunity to:
  • 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.
