Job Title Infleqtion is on a mission to commercialize atom-based quantum technologies that deliver orders-of-magnitude improvements in sensing and computing applications. As a deep-tech startup, we embrace a results-driven, fast-paced, and customer-focused approach to innovation. We are seeking self-motivated, energetic individuals with exceptional problem-solving and technical skills to help drive our Quantum Sensing mission forward. We encourage applications from physicists with computational and/or theoretical backgrounds, particularly those with experience in Atomic, Molecular, and Optical (AMO) physics and coherent control of quantum systems such as ultra-cold atoms or multi-level systems. Role and Responsibilities Design, build, and test numerical simulations of physical systems, and work with experimental colleagues to incorporate real-world physical effects into the simulations Use GPUs or other High Performance Computing techniques to speed-up simulations Drive results and present findings to customers Stay up-to-date on literature, assess and pursue cutting edge quantum simulations for novel applications Communicate and interpret cutting-edge research in both theory and experiment with colleagues Customer-centric focus on solving end-user needs and proposing new work to customers Ownership of codebases to maintain high usability and performance. Mentor and teach junior team members as indirect reports. Supervise interns. Work will normally be performed in an office and laboratory environment and around technical equipment including computers and lasers. We ask that candidates be able to efficiently use automated office equipment such as laptops, copiers, and printers; able to effectively engage in communications (via phone, computer, or in-person). Any required Personal Protective Equipment will be provided and must be properly used in accordance with company requirements.
