We are seeking an Advanced Quantum Compiler Engineer in our Broomfiel, CO Location.

Our compiler team builds the software that makes our quantum computers useful. We turn quantum programs into hardware-ready instructions that can run efficiently on our trapped-ion systems, and we solve the hard compiler problems required to scale performance as the technology advances.

As an Advanced Quantum Compiler Engineer, you will develop the languages, optimization passes, and hardware-aware compilation strategies that power next-generation quantum computing. You will work across the stack - from front-end tooling to real-time, high-performance backends - with a focus on performance, correctness, and scalability.

This role is ideal for someone who wants to tackle deep compiler challenges in a fast-moving R&D environment. You will help shape how quantum programs are optimized, routed, and executed, and your work will directly influence the capabilities of our quantum systems.

All applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test.

Key Responsibilities:

• Contribute to the development of compiler front-end (quantum languages), back-end (machine-specific targeting), and optimization (quantum circuit optimization and classical optimization) passes operating on both classical and quantum operations
• Benchmark, profile, and optimize the execution of our compiler and the quality and performance of quantum programs it generates
• Collaborate on the design and implementation of a compiler targeting a real-time, distributed, execution environment
• Work with a diverse team including physicists and other engineering disciplines to solve complex problems
• Write high quality, maintainable code in an R&D and rapid prototyping environment

YOU MUST HAVE:

• Bachelors Degree Minimum
• Minimum 4+ years of industry or post-graduate experience in an engineering, lab, or R&D environment
• Minimum 3+ years of programming experience with Rust, C++, or similar language
• Coursework in compiler fundamentals and a strong understanding of compiler design
• Due to Contractual requirements, must be a U.S. Person defined as, U.S. citizen permanent resident or green card holder, workers granted asylum or refugee status
• Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.

WE VALUE:

• Masters/PhD degree in Computer Science, EE, Physics or other relevant field

• Ability to understand, combine, and apply algorithms to solve complex problems
• Experience developing and extending compiler infrastructures (LLVM, MLIR, GCC, Cranelift, custom research compilers, or equivalent).
• Ability to solve complex problems and ability to communicate how you did it
• Track-record using python or other rapid prototyping and development tools to solve complex challenges
• Rust development experience with a track-record of contribution to open-source and commercial projects
• Demonstrated ability to work with a variety of algorithms, including tree, graph, SAT, and, at times Machine Learning and other algorithms
• Experience with development of application-specific algorithms, especially where exact/optimal solutions are computationally intractable
• Experience with testing and correctness verification of compiler transformations and optimizations
• Proficiency with software testing and deployment tools

$138,000 - $173,000 a year

Compensation & Benefits:

The pay range for this role is $138,000 - $173,000 annually. Actual compensation within this range may vary based on the candidate's skills, educational background, professional experience, and unique qualifications for the role.

By joining Quantinuum, you'll be at the forefront of this transformative revolution, shaping the future of quantum computing, pushing the limits of technology, and making the impossible possible.
