Job summary

Infleqtion is seeking a Staff Quantum Sensor Physicist to translate customer needs into practical architectures for deployable atom-based inertial and gravitational sensors. You will lead R&D across atom interferometry, laser systems, vacuum hardware, and controls, collaborating with cross-disciplinary teams to deliver robust sensor solutions.

The ideal candidate holds a PhD, has hands-on experience with atom-based sensors, and can effectively communicate with customers.

Qualifications

• PhD in atomic physics, optical physics, quantum sensing, precision measurement, or related field.

Responsibilities

• Participates in and/or leads research and development projects involving atom interferometry, atom-based inertial and gravitational sensing, cold-atom systems, laser systems, vacuum systems, controls, and quantum sensing systems
• Translates customer needs, use cases, and specifications into practical quantum sensor architectures, requirements, error budgets, trade studies, operating concepts, and development plans
• Leads or supports development from concept and architecture phases all the way through test, operation, and eventual deployment
• Develops and maintains physics models, simulations, calculations, and error budgets to guide architecture decisions, performance estimates, and identification of technical risks
• Evaluates sensor concepts against real-world and deployed-system constraints including sensitivity, bandwidth, dynamic range, SWaP-C, environmental robustness, manufacturability, reliability, cost, schedule, and technical risk
• Works with electrical, mechanical, software, firmware, vacuum, laser, and controls engineering teams to develop requirements, guide design trades, and convert physics concepts into buildable and operable instrument designs
• Participates in proposal development and customer technical discussions, including practical work scope, risks, system concepts, and deployment consideration
• Communicates project findings and progress to both internal stakeholders and external customers
