Quantum Software Engineer - Applications

The newly hired Quantum Software Engineer – Applications will join the Applications team in Infleqtion’s Quantum Software division and contribute to the development of quantum algorithmic solutions for real-world problems. This role will involve the identification and selection of candidate problems for demonstration on early fault-tolerant QPUs, implementation and demonstration of quantum solutions, and assessment of resource needs for deployment at scale. As a member of the Quantum Software division, this role will involve close collaboration with teams working on the development of Superstaq, Infleqtion’s quantum software platform, and Sqale, Infleqtion’s neutral atom quantum computer.

Job Responsibilities

The 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:
