At Quantum Circuits Inc., we are building the world’s first truly algorithmic quantum computers to achieve transformational computing capabilities. Our full-stack quantum computing platform uses superconducting devices along with a modular, robust, and scalable architecture. Our unique approach is based on a decade of technology research and breakthroughs at Yale University's world-renowned quantum labs.
We are seeking a talented and experienced Senior Quantum 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 such as applications, quantum physicists, and embedded control to design, develop, and deploy innovative solutions.
Responsibilities:
- Collaborate with product managers, scientists, and other engineers to translate functional requirements into technical specifications and deliverables.
- Work directly with quantum application engineers and 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 physicists driving 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, and/or another general-purpose programming language such as Java.
- Minimum 2+ years developing compiler software / transpiling quantum models and using APIs such as Qiskit, CUDA Quantum, or Q# to convert quantum circuits into quantum logic and basis gates.
- Experience programming with one or more high-level quantum programming languages and/or models including Qiskit, CUDA Quantum, Q#, etc.
- Proficient in 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:
- Ph.D. in Computer Science, Electrical/Computer Engineering, Math, Physics, or Chemistry.
- Minimum 7+ years of hands-on software development experience with C, C++, Python, and/or another general-purpose programming language such as Java.
- Minimum 5+ years developing compiler software / transpiling quantum models and using APIs such as Qiskit, CUDA Quantum, or Q# 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 including Qiskit, CUDA Quantum, Q#, etc.
- Experience in scientific computing, quantum physics, or quantum computing a plus.
- Experience with embedded systems, algorithms, and/or low-level control software for hardware a plus.
- Experience with multi-threaded programming, execution, and HPC architectures.
