  • 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

YOU MUST HAVE:

  • Bachelors Degree minimum
  • Minimum 1+ years of industry or post-graduate experience in an engineering, lab, or R&D environment
  • Minimum 2+ years of experience developing for quantum compilers and/or quantum algorithms
  • Minimum 3+ years of programming experience with Python, Rust, C++, or similar language
  • 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:

  • Masters/PhD degree in Computer Science
  • Strong understanding of compiler design fundamentals
  • Ability to understand, combine, and apply algorithms to solve complex problems
  • Ability to solve complex problems and ability to communicate how you did it
  • Track-record of using python or other rapid prototyping and development tools to solve complex challenges
  • 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
  • History of working with and developing for the LLVM toolchain
  • Experience with LLVM IR and MLIR
  • Experience with development of application-specific algorithms, especially where exact/optimal solutions are computationally intractable
  • Proficiency with software testing and deployment tools
Compensation & Benefits:
Non-Incentive Eligible
Estimated Salary Wage: $97,000 - $122,000 Annually
What is in it for you?
-A competitive salary and innovative, game-changing work
