We are seeking a Quantum Compiler Engineer for our Broomfield, CO location.
Our compiler team is at the forefront of bridging the gap between groundbreaking quantum applications and the unparalleled computing power of quantum machines. As a Quantum Compiler Engineer, you are invited to join an interdisciplinary team of physicists and software developers dedicated to transforming platform agnostic quantum algorithms into concrete, executable instructions tailored for our state-of-the-art trapped-ion quantum computers.
In this role, you will engage in pioneering work, collaborating closely with compiler specialists to forge user-friendly languages and tools designed for crafting quantum programs. Your expertise will be instrumental in advancing the development of sophisticated heuristics and algorithms. These innovations are critical for optimizing the routing of ions across complex topologies, significantly enhancing the speed and efficiency of quantum applications executed on our platforms.
By contributing to our team, you will not only play a key role in optimizing code generation for quantum computing but also in shaping the future of quantum technology. Your work will ensure that our quantum computers can realize their full potential, unlocking new possibilities for solving some of the world's most challenging problems.

Key Responsibilities:

    • Design and develop 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 iteratively improve the execution performance of our compiler and the quality and performance of quantum programs aligned to current and future architectures
    • 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
    • Create high quality code in an R&D and rapid prototyping environment


    • Bachelors Degree
    • Minimum 2+ years of industry or graduate experience in an engineering, lab, or R&D environment
    • Minimum 2+ years of programming experience with Python, Rust, C++, or similar language
    • Applicants for employment for this position must have work authorization that does not now or in the future require sponsorship of a visa for employment authorization in the United States and with Quantinuum (i.e., H1-B visa, F-1 visa (OPT), TN visa or any other non-immigrant status).


    • Masters/PhD degree in Computer Science 
    • Ability to solve complex problems and ability to communicate how you did it
    • Rust development experience especially including any LLVM or optimization algorithm development
    • Demonstrated ability to work with a variety of algorithms, including tree, graph, SAT, and, at times Machine Learning and other algorithms 
    • Experience with domain-specific language development or programming language development
    • History of working with and developing for the LLVM toolchain
    • Experience with LLVM IR or MLIR
    • Experience with development of application-specific algorithms, especially where exact/optimal solutions are computationally intractable
    • Proficiency with software testing and deployment tools
$126,000 - $157,000 a year
