Original job description

Position Summary This Quantum Software Engineer role will join the Compiler Team within Infleqtion’s Quantum Software organization. This role will be responsible for designing, building, and maintaining quantum compilation software alongside considerable involvement in co-design efforts that span the full quantum stack, including applications, algorithms, hardware and control. This role combines hands-on coding, code review, and system design with R&D. Ideal candidates have a strong software development background and familiarity with quantum computation. This role is open to both entry-level and senior-level candidates. 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.

Conduct R&D toward cutting-edge advances in quantum technology with a focus on quantum compilation, similar to work described in https://arxiv.org/abs/2309.05157 and https://arxiv.org/abs/2509.13247
