Job Description

Xanadu is seeking a highly skilled Quantum Software Developer to join our team.

We are a company that is building quantum computers that are useful and available to people everywhere. Our mission is to create something that has never been built before, and we are looking for talented individuals to help us achieve this goal.

About the Role

As a Quantum Software Developer, you will be responsible for developing and maintaining JIT and AOT hybrid compilation pipelines for PennyLane, an open-source software framework for quantum machine learning, quantum computing, and quantum chemistry.

Your key responsibilities will include:

  1. Converting abstract descriptions of algorithms into efficient and understandable software implementations.
  2. Performing R&D to support new hardware platforms, programming paradigms, and software tooling to enable optimal performance for quantum computing workloads.
  3. Interpreting and communicating complex concepts to the wider team.
  4. Participating in software system specification, design, and quality assurance (e.g., requirements gathering, defining software architecture, documentation, verification & validation, etc.).
  5. Providing leadership in software best practices, including continuous-integration pipelines, unit testing, documentation, and code reviews.

Requirements

To be successful in this role, you will need:

  1. A Bachelor's Degree in Physics, Computer Science, Math, Engineering, or a related field.
  2. 2+ years of development experience in modern optimizing compilers, for a variety of architectures.
  3. Strong knowledge of Python and C++.
  4. Experience with benchmarking and performance-oriented optimizations.
  5. Strong focus on testing and software quality.

Preferred Qualifications

We are looking for candidates with:

  1. Experience developing projects using MLIR and/or LLVM.
  2. Understanding of advanced compiler optimization techniques.
  3. Familiarity and experience with automatic differentiation methods and frameworks (e.g., Autograd, Torch, TensorFlow, JAX).
  4. Education or training in quantum computing (such as work experience, coursework, thesis, or peer-reviewed publications).
  5. Experience developing toolkits, compilers, or runtime environments for heterogeneous architectures.

Our Values

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.
