Job summary

Infleqtion is seeking a Staff Quantum Physicist to lead design, integration, and operation of neutral‑atom quantum computing systems. The role emphasizes hands‑on technical leadership, system development, and mentoring across teams in a fast‑paced, AMO‑oriented environment.

You will translate goals into experimental plans, develop Python tools for control and data analysis, and drive performance improvements in gate fidelity and processor reliability.

Qualifications

• PhD in atomic, optical, AMO, quantum physics or equivalent; typically 5+ years post‑PhD experience or equivalent leadership in complex quantum systems.
• Hands‑on experience designing, operating, or improving AMO or coherent‑control experiments with atom–light interactions and laser/optics tech.
• Proficiency with Python for control, data analysis, automation; working knowledge of Linux and version control.
• Ability to translate ambiguous goals into executable plans and lead cross‑disciplinary system work.

Responsibilities

• Lead the design, integration, calibration, operation, and improvement of neutral‑atom quantum computing systems and subsystems.
• Translate program goals into technical requirements, experimental plans, performance targets, and direction across processor design, Rydberg excitation, laser systems, and calibration.
• Design experiments and models to improve gate fidelity, stability, availability, and processor performance; guide tradeoffs.
• Own critical systems through validation, troubleshooting, performance tuning, and documentation; drive cross‑functional delivery.
• Develop Python‑based tools in Linux environments for experiment control, data analysis, calibration, automation, and support.
• Review technical work and uphold team standards and best practices.
• Manage up to six direct reports, including expectations, performance, coaching, and career development.
• Contribute to hiring, proposals, roadmaps, and external technical discussions.
