Job description

Quantum Software Developer - Compilation (Hybrid)

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. If successful, the technologies we develop will solve some of the world’s most challenging problems and change the world. That is something to be excited about!

Your role and responsibilities :

As part of the PennyLane Compilation team, you will develop and maintain JIT and AOT hybrid compilation pipelines for PennyLane, an open-source software framework for quantum machine learning, quantum computing, and quantum chemistry.

You will :

• Convert abstract descriptions of algorithms into efficient and understandable software implementations.
• Perform R&D to support new hardware platforms, programming paradigms, and software tooling for optimal quantum computing performance.
• Interpret and communicate complex concepts to the wider team.
• Participate in software system specification, design, and quality assurance, including requirements gathering, software architecture, documentation, verification, and validation.
• Provide leadership in software best practices, including continuous integration pipelines, unit testing, documentation, and code reviews.

Basic qualifications and experience :

• Bachelor’s Degree in Physics, Computer Science, Math, Engineering, or related field.
• 2+ years of experience in developing modern optimizing compilers for various architectures.
• Strong knowledge of Python and C++.
• Experience with benchmarking and performance optimizations.
• Focus on testing and software quality.

Preferred qualifications and experience :

• Experience with MLIR and/or LLVM projects.
• Understanding of advanced compiler optimization techniques.
• Experience with automatic differentiation frameworks (e.g., Autograd, Torch, TensorFlow, JAX).
• Education or training in quantum computing (e.g., coursework, research, publications).
• Experience developing toolkits, compilers, or runtimes for heterogeneous architectures.
