Quantum Software Engineer
Job Description
Job Title: Quantum Software Engineer Role Summary: Design, develop, and maintain quantum compilation software as part of a cross‑functional quantum stack team. The role blends hands‑on coding, system design, R&D, and collaboration with physicists, customers, and other engineers to advance quantum compilation technologies and productize solutions. Expectations: Deliver production‑grade code, perform code reviews, and adhere to robust engineering practices. Engage in R&D, publish findings, interface with customers, contribute to proposals, and support global programs. Work independently in a dynamic environment, travel up to 10 % internationally, and attend on‑site meetings three days per week. Key Responsibilities: • Conduct R&D on quantum compilation algorithms and optimizations. • Build and maintain compiler components for cloud platform deployment. • Apply industry‑grade engineering practices: documentation, linting, testing, and type‑checking. • Interface with customers to understand needs and provide support. • Collaborate with experimental physicists and software engineers to translate theory into practice. • Prepare and contribute to government and commercial proposals. • Publish research and present at conferences. • Guide and mentor team members, fostering a collaborative research culture. Required Skills: • Proficient in Python; experience with C/C++ or Julia, and rapid up‑skilling in Python. • Deep familiarity with Cirq or Qiskit and ability to modify open‑source libraries. • Strong software engineering fundamentals: version control, CI/CD, automated testing, coverage, type checking, profiling, documentation. • Knowledge of quantum computing concepts: error correction/fault tolerance, native gate decomposition, qubit mapping/routing, variational quantum algorithms. • Experience with cloud platforms (GCP, AWS) and backend development (FastAPI, PostgreSQL/SQLAlchemy). • Familiarity with security best practices (access control, encryption, key rotation, logging). • Excellent communication, collaboration, and problem‑solving skills. • Ability to learn complex topics quickly and thrive in a fast‑paced environment. Required Education & Certifications: • Bachelor’s degree in Computer Science, Engineering, Physics, or a directly related field. • PhD in Quantum Computation, Physics, Computer Science, or related discipline preferred.
