Infleqtion is commercializing atom-based quantum technologies for sensing and computing applications. We are seeking an experienced quantum physicist to design, integrate, calibrate, and operate neutral-atom quantum computing systems.
In this role, you will:
- Design, integrate, calibrate, operate, and improve neutral-atom quantum computing systems and critical subsystems
- Lead R&D projects involving quantum processor hardware, quantum-gate protocols, laser and optical systems, calibration, control, and system integration
- Translate program goals into technical requirements, experimental plans, and measurable performance targets
- Design and analyze experiments and physics-based models to identify performance limitations and guide technical decisions
- Independently own critical systems through development, validation, troubleshooting, reliability improvement, and routine operation
- Develop Python-based tools for experiment control, data analysis, calibration, automation, and hardware integration
- Collaborate across physics, software, electrical, mechanical, and systems-engineering teams
- Mentor junior team members and interns; contribute to technical reviews and team best practices
Work is performed in an office and laboratory environment around technical equipment including computers and lasers. Up to 10% travel may be required. Personal protective equipment will be provided as needed.
QUALIFICATIONS (Required):
- PhD in atomic, optical, AMO, quantum physics, or related field plus at least two years of relevant post-PhD experience, or comparable professional experience developing complex experimental systems
- Hands-on experience designing, building, and operating complex AMO, quantum-control, or precision-measurement experiments
- Experience applying quantitative atomic or optical physics models to experimental design or specification of laser, optical, RF, or control systems
- Hands-on experience with lasers and optical systems, including acousto-optic or electro-optic modulators, RF instrumentation, imaging systems, or ultra-high-vacuum equipment
- Experience using Python for experiment control, data analysis, automation, or hardware integration
- Evidence of independently leading a substantial experimental project or owning a critical technical subsystem
QUALIFICATIONS (Preferred):
- Experience with neutral-atom quantum computing, Rydberg physics, optical-tweezer arrays, or quantum-gate characterization
- Experience with advanced laser systems, optical beam delivery, high-NA imaging, beam shaping, or optical projection
- Experience characterizing and mitigating laser-frequency, phase, pointing, or intensity noise
- Experience with analog electronics, RF systems, or feedback control
- Experience integrating optical, electronic, vacuum, control, and software subsystems
- Experience developing automated calibration, health-monitoring, or experimental test infrastructure
- Familiarity with Linux, Git, command-line tools, and collaborative software-development practices
Note: This position may require access to information protected under U.S. export control laws and regulations for quantum computing technology. Any offer may be conditioned on authorization to receive software or technology controlled under these regulations without sponsorship for an export license.
