Job Description

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:

Contribute to the development of quantum algorithmic solutions for real-world problems by developing and implementing custom quantum software, including testing and evaluation through simulation and hardware execution.

Customer-centric focus on solving end-user needs and proposing new work to customers

Stay up-to-date on literature, assess and pursue cutting edge quantum algorithms for novel applications

Communicate and interpret cutting-edge research in both theory and experiment with colleagues

Engage with the broader scientific community by publishing research findings in scientific journals and presenting at conferences

Stay up to date with the latest developments in quantum algorithms and quantum application development

Provide guidance and support to other team members, working closely with them to foster a collaborative research environment
