Infleqtion (Coldquantlabs/Super.tech) is a global quantum technology company solving the world’s most challenging problems. The company harnesses quantum mechanics to build and integrate quantum computers, sensors, and networks. From fundamental physics to leading edge commercial products, Infleqtion enables “quantum everywhere” through our ecosystem of devices and platforms. We are recruiting for a Quantum Software Engineer - Machine Learning and Optimization. LOCATIONInfleqtion has 6 office locations, operating out of Austin, TX; Boulder/Louisville, CO; Madison, WI; Chicago, IL; Oxford, UK; and Melbourne, AU. This position is a full-time, hybrid position which will be located in our Oxford, England office. Job Summary Infleqtion UK is looking for a quantum engineer who will be responsible for developing and delivering machine learning & optimization solutions based on quantum technologies. The engineer will drive work that contemplates the full quantum software stack, from applications to compiler to awareness of underlying hardware/controls. Job ResponsibilitiesThe duties and responsibilities outlined below include essential functions of the role. Depending on business needs, this role may perform a combination of some or all of the following duties. Duties, responsibilities, and activities may change, or new ones may be assigned at any time with or without notice.

• Develop quantum machine learning and optimization solutions for end users in industries such as defense and logistics
• Tailor solutions using full-stack quantum software optimizations: these optimizations can span the full stack, from algorithmic improvements, compiler optimizations, and pulse-level control techniques to force-multiply the capabilities of underlying quantum hardware (we target both NISQ and fault-tolerant hardware)
• Deploy software optimizations to our cloud platform (Superstaq) with industry-grade software engineering procedures including documentation, linting, testing, and type-checking
• Interface with customers of Superstaq to understand their needs and support them in a timely fashion
• Conduct R&D toward cutting-edge advances in quantum technology. Write and manage funding proposals to multi-million-dollar programs across the globe

Requirements

• Master’s or PhD-level training in computer science, engineering, physics or directly related field
• At least three (3) years of experience in quantum technology or machine learning, with at least two (2) years of professional industry-level quantum software work experience
• Strong familiarity with quantum computing is necessary, as well as familiarity with state-of-the-art tools for (classical or quantum) machine learning & optimization
• Experience with open-source quantum software frameworks such as Cirq or Qiskit; Ideal candidates will have experience not only using these libraries but also modifying them
• Experience with open-source machine learning & optimization frameworks such as PyTorch, SciPy, and scikit-learn; Ideal candidates will have experience not only using these libraries but also modifying them
• Experience with python programming and software engineering best practices; Ideal candidates will have an active track record on Github/Gitlab, contributing to open-source repositories or building their own repositories
• Strong work ethic and drive; Appetite for working at the frontiers of quantum technology
• Demonstrated ability to effectively share information with technical and non-technical staff
• Demonstrated ability to learn new and complex topics quickly
• Demonstrated ability to work and communicate with all levels of an organization; Professional-level communication skills, including verbal, written, and presentation skills
• Demonstrated ability to work comfortably in a highly collaborative, cross-functional, and team-oriented environment
• Desire and demonstrated ability to thrive and produce results in a fluid, dynamic, and fast-paced environment; Orientation towards execution
• Passion for solving complex problems and challenges in a highly technical and scientific environment
• Proficient in MS Office
