Principal Quantum Compiler Engineer - 924

US Broomfield, COSenior8+ years

We are seeking a Principal 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 hands-on technical leadership role, you will shape the compiler roadmap by architecting, prototyping, and evaluating technologies that advance the languages, tooling, and optimization strategies used to develop and execute programs efficiently on our quantum platforms. You will champion engineering standards and practices through direct technical contributions, feedback, and mentorship and influence how our compiler stack evolves to support increasingly capable quantum hardware. Working closely with key technical leaders, you will co-develop strategies that will enable execution of fault tolerant quantum programs at scale.

Through your contributions, you will be a key driver of the strategy shaping key compiler technologies powering the next generation of fault-tolerant quantum computers that will ultimately 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:

Drive strategic vision and leadership in architecture and implementation of compilers targeting advanced quantum computer capabilities.

Collaborate with industry leaders, academic researchers, and standards organizations to shape emerging quantum programming and compiler standards.

Mentor and develop technical leadership within the compiler team to build long-term organization capability and architectural vision.

Architect and contribute to advanced compiler design projects and development including:

Compiler front-end (quantum languages)
Back-end (machine-specific targeting)
Optimization passes (quantum circuit optimization and classical optimization) operating on both classical and quantum operations
Cross-disciplinary collaboration and technical leadership while working with a diverse team including physicists and other engineering disciplines to solve complex problems.
Champion code quality and engineering excellence, leading by example while contributing high quality code in an R&D and rapid prototyping environment.

YOU MUST HAVE:

Master’s degree minimum

Minimum 8+ years of industry or post-graduate experience in an engineering, lab, or R&D environment.

Minimum 8+ years of hands-on experience developing compiler infrastructure and technologies.

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:

Master’s or PhD in Computer Science, Electrical Engineering, or a relevant field, or equivalent demonstrated experience in compiler research and development

Strong understanding of compiler architecture and design principles, with the technical judgment to drive architectural decisions across complex compiler systems.

Significant experience extending or developing compiler infrastructure using LLVM or comparable compiler frameworks.

Demonstrated track record of leading the development of innovative algorithmic solutions to complex optimization problems and clearly communicating design decisions, tradeoffs, and impact to technical and cross-functional stakeholders.

Exceptional communication skills, with the ability to clearly articulate architectural direction, explain key tradeoffs, and align short-, medium-, and long-term plans to deliver sustainable success.

Experience with Rust or a strong understanding of Rust’s core technical principles and design philosophies.

Experience or familiarity with Fault-Tolerant Quantum Computation

Experience as a technical lead in an academic or industry R&D team focused on development of compiler technologies

A track-record of contribution to open-source and commercial projects

Demonstrated ability to work with a variety of algorithms, including tree, graph, SAT, machine learning and other algorithms

Experience with MLIR or other high-level IR

Experience with development of application-specific and heuristic algorithms, especially where exact/optimal solutions are computationally intractable

Proficiency with software testing and deployment tools
