Advanced Quantum Compiler Engineer - 925

US Broomfield, COScience & Technology – Quantum Computing Software /Full-time /HybridWe are seeking an Advanced Quantum Compiler Engineer in our Broomfield, CO Location.As quantum hardware rapidly scales toward fault-tolerant systems, compiler technology is becoming one of the fundamental enablers of practical quantum computing.At Quantinuum, our compiler team develops critical software that translates our users’ groundbreaking quantum applications to hardware-specific operations that execute efficiently on our world-class hardware. We tackle some of the hardest compiler and optimization problems in quantum computing, including scalable routing across trapped-ion architectures, compilation for fault-tolerant quantum systems, and architecture-aware optimizations. With the support of physicists, quantum error correction (QEC) experts, and fellow compiler engineers, we co-design the software stack that will compile algorithms into tailored, executable instructions for our trapped-ion quantum computers. Through this work, we are building the compiler technologies that enable scalable, fault-tolerant quantum computing on increasingly capable hardware.In this role, you will design, implement, and optimize software used at compile-time and run-time that enables our next-generation quantum computing platforms. You will be responsible for projects that design and implement new platform capabilities and expose them to users. Working with subject matter experts, your contributions will develop new and improve existing quantum platform capabilities and optimize the execution of logical and physical quantum circuits.As a member of our team, you will help build the compiler technologies that make large-scale quantum computing possible.  You will directly impact how future quantum computers are programmed, optimized, and ultimately used to solve problems beyond the reach of classical computing.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 operationsBenchmark, profile, and optimize the execution of our compiler and the quality and performance of quantum programs it generatesCollaborate on the design and implementation of a compiler targeting a real-time, distributed, execution environmentWork with a diverse team including physicists and other engineering disciplines to solve complex problemsWrite high quality, maintainable code in an R&D and rapid prototyping environmentYOU MUST HAVE:Bachelor’s Degree minimumMinimum 3+ years of industry or post-graduate experience in an engineering, lab, or R&D environmentMinimum 3+ years of programming experience with Rust, C++, or similar languageDue 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 statusDue 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 fieldCoursework in compiler fundamentals and a strong understanding of compiler designAbility to understand, combine, and apply algorithms to solve complex problemsExperience 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 itTrack-record using python or other rapid prototyping and development tools to solve complex challengesRust development experience with a track-record of contribution to open-source and commercial projectsDemonstrated ability to work with a variety of algorithms, including tree, graph, SAT, and, at times Machine Learning and other algorithmsExperience with development of application-specific algorithms, especially where exact/optimal solutions are computationally intractableExperience with testing and correctness verification of compiler transformations and optimizationsProficiency with software testing and deployment tools$138,000 - $173,000 a yearCompensation & Benefits:The pay range for this role is $138,000 – $173,000 annually.
