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. This is an exciting opportunity!

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 framework for quantum machine learning, quantum computing, and quantum chemistry.

You will:

• Convert abstract algorithm descriptions into efficient, understandable software implementations.
• Conduct R&D to support new hardware platforms, programming paradigms, and software tools to optimize quantum workloads.
• Interpret and communicate complex concepts to the team.
• Participate in software system specification, design, quality assurance, documentation, verification, and validation.
• Lead best practices in software development, including CI 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 with modern optimizing compilers for various architectures.
• Strong knowledge of Python and C++.
• Experience with benchmarking and performance optimization.
• Focus on testing and software quality.

Preferred qualifications and experience:

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