Software Developer - Systems Integrations Tooling

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:

As a Software Developer, you will contribute to the platform and the infrastructure for our software and hardware products. You will work on a team to support Hardware R&D, Hardware Operations, Cloud Infrastructure, and Developer Enablement. The Tools Team’s primary goal is to help accelerate the Hardware Team’s timelines to build the first commercially viable quantum computer. As a result, you will completely reshape the nature of computation as we know it. You will:

• Design and build interactive graph visualization interfaces using modern web technologies (e.g., WebGL, React) to render and navigate hierarchical networks and systems at scale.
• Develop and maintain the Python backend, including graph data models, serialization, and querying APIs for internal consumption.
• Optimize for performance across both frontend rendering and backend data processing, ensuring responsiveness with datasets containing millions of nodes and edges.
• Collaborate closely with quantum physicists, systems architects, and other developers to translate scientific requirements into intuitive, usable tools.
• Maintain code quality through automated test coverage (pytest), CI/CD pipelines (GitHub Actions), and thorough code reviews.

Basic qualifications and experience:

• BSc in Computer Science, Engineering, or a related field.
• 4+ years of software development experience.
• Previous experience with front‑end development frameworks and tools (React, Typescript).
• Strong knowledge of modern development languages like Python and/or web backend frameworks.
• Experience with any major cloud providers: AWS, GCP or Azure.
• In-depth knowledge of different software development methods such as Test Driven Development, Unit Testing, Agile, etc.
• Self‑driven to deliver high‑quality solutions to your stakeholders.
• Comfortable working in a fast‑paced environment.
• Strong communication and collaboration skills.

Preferred qualifications and experience:

• Familiarity with graph visualization at scale (rendering 10K+ nodes interactively, level‑of‑detail techniques, lazy loading/virtualization).
• Experience with graph libraries such as rustworkx or NetworkX.
• Experience with UI/UX, industrial control panels, scientific HMI, user‑centered design.
• Experience with AWS (S3, RDS DB, lambda, ECS).
• Experience with performance profiling and optimization (memory profiling, time complexity analysis, benchmarking).
• Proven record of bootstrapping frontend projects end to end.
• Experience developing and maintaining software related infrastructure (CI/CD pipelines, GitHub Actions, containerization).

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.
