We are seeking a talented and experienced Senior Software Engineer to join our dynamic team and work on developing key pieces of QCI’s software platform and tools focusing primarily on our compiler and interface to various quantum programming environments. The ideal candidate will have a strong background in developing tools and transpilation layers converting general quantum circuits into gate and lower-level quantum control sequences. You will work closely with cross-functional teams including application engineers, quantum physicists, and embedded software engineers to design, develop, and deploy innovative solutions.
Responsibilities / Description:
- Collaborate with product managers, scientists, and other engineers to translate functional requirements into technical specifications and deliverables.
- Work directly with quantum application engineers and quantum physicists to understand how to convert general quantum circuits into an implementation on our industry-leading dual-rail qubit architecture.
- Architect and build efficient, reliable, 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 to quantum physicists on best practices and help drive software best practices.
- Remote or hybrid position based in New Haven, CT to be discussed with the candidate.
- Sponsorship available.
Minimum Qualifications:
- Minimum MS or higher in Computer Science, Electrical/Computer Engineering, Math, Physics, or Chemistry.
- Minimum 5+ years of hands-on software development experience with C, C++, Python, or another general-purpose programming language.
- Minimum 2+ years developing compiler software / transpiling quantum models and using API’s such as Qiskit, CUDA-Q, Q#, or Cirq to convert quantum circuits into quantum logic and basis gates.
- Strong understanding of compiler design fundamentals.
- 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#, Cirq, etc.
- 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 effectively in a collaborative team environment.
- Excellent communication and interpersonal skills with the ability to effectively communicate complex technical concepts.
Preferred Qualifications:
- PhD in Computer Science, Electrical/Computer Engineering, Math, Physics, or Chemistry.
- Minimum 7+ years of hands-on software development experience with C, C++, Python, or another general-purpose programming language..
- Minimum 5+ years developing compiler software / transpiling quantum models and using APIs such as Qiskit, CUDA-Q, Q#, or Cirq to convert quantum circuits into quantum logic and basis gates
- Minimum 2+ years directly programming with one or more high level quantum programming languages and/or models such as Qiskit, CUDA Quantum, Q#, etc.
- Experience in scientific computing, quantum physics, or quantum computing a plus.
- Experience developing toolkits, compilers, or runtime environments for heterogenous architectures.
- Experience with ahead-of-time and just-in-time compilation for quantum computing.
- Experience with embedded systems, algorithms, and/or low-level control software for hardware a plus.
- Experience with multi-threaded programming, execution, and HPC architectures.
- Experience with meta programming languages.
