Quantum Compiler Engineer

Quantum Compiler Engineer

Location:

Broomfield, CO

We are seeking a Quantum Compiler Engineer for our Broomfield, 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 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.

• 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

• Bachelor’s 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 a 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

• 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

The pay range for this role is $136,000–$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.

• 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, 401(k) retirement savings plan and 12 paid holidays and generous vacation and sick time
• Paid parental leave
• Employee discounts
