Senior Quantum Compiler Engineer

D-Wave Quantum Inc.; New Haven (CT); On-site; USD 125,000 - 187,000; Full time

Job summary

D‑Wave Quantum Inc. in New Haven, CT, is seeking a Senior Quantum Software Engineer, Compiler, to advance our compiler and interface to quantum environments.

You will convert general quantum circuits into gate-level implementations for our dual-rail qubit architecture and collaborate with engineers, physicists, and application teams. The role requires 5+ years of software experience in C/C++, Python, and a strong background in compiler design, IRs, and quantum programming languages.

Qualifications

• Master’s degree in computer science, electrical/computer engineering, math, physics, chemistry, or equivalent experience with strong physics aptitude.
• 5+ years of hands-on software development experience with C, C++, Python, or another general-purpose compiled programming language.
• Strong understanding of compiler design fundamentals.
• 2+ years developing compiler software/transpiling quantum models and using quantum API’s (Qiskit, CUDA-Q, Q#, or Cirq) to convert quantum circuits into quantum logic and basis gates.
• Experience with intermediate representations such as QIR and compiler toolchain technologies including LLVM, MLIR, lexers, and parsers.
• Experience programming with one or more high level quantum programming languages and/or models such as Qiskit, CUDA-Q, Q#, or Cirq.
• Proficient with database systems and SQL with hands-on experience working with relational databases (e.g. PostgreSQL, Oracle).
• Competence with Git version control, build tools, and CI/CD pipelines.
• Use of software testing principles and practices, including unit testing, integration testing, and end-to-end testing.
• Strong problem-solving skills, attention to detail, and the ability to work in a collaborative team environment.
• Excellent communication and interpersonal skills with the ability to effectively communicate complex technical concepts.

Responsibilities

• Collaborate with product managers, scientists, and other engineers to translate functional requirements into technical specifications and robust solutions.
• Work directly with quantum application engineers and quantum physicists to understand how to convert quantum circuits into implementations targeting our industry-leading dual-rail qubit architecture.
• Architect and build efficient, reliable, scalable, and maintainable compiler software and tools.
• Write clean, well-documented code and conduct thorough code reviews to ensure code quality and maintainability.
• Troubleshoot and debug issues, identify bottlenecks, and implement solutions to optimize performance and improve the user experience.
• Provide software mentorship and guidance on best practices and help drive adherence to software best practices.
