Quantum Compiler Engineer - 466

Quantinuum • Broomfield, CO

4d • Onsite

About The Position

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 a 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.

Requirements

• Bachelors Degree minimum
• Minimum 2+ 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.

Nice To Haves

• Masters/PhD degree in Computer Science
• History of working with and developing for the LLVM toolchain
• 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
• Proficiency with software testing and deployment tools

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

Benefits

• A competitive salary and innovative, game-changing work
• Flexible work schedule
• Employer subsidized health, dental, and vision insurance
• 401(k) match for student loan repayment benefit
• Equity, 401k retirement savings plan + 12 Paid holidays and generous vacation + sick time
• Paid parental leave
• Employee discounts
