Staff Quantum Physicist, Hardware Systems Lead

Help Infleqtion build the future of quantum in Illinois. We are 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 deploying a neutral-atom quantum computer in Chicago and are seeking a leader to build, manage, and develop the team that will bring it to life. You will lead the hardware team’s technical execution and people’s development. You will collaborate with our facilities and project management personnel to help the new team succeed at our new Chicago quantum hardware lab. 

Your primary responsibility will be to enable a talented team to succeed. You will set up technical priorities, shape and ratify high-impact technical decisions, coach and develop team members, and create an environment where physicists and engineers can do their best work. You will also partner with experts across Infleqtion to advance our neutral-atom quantum computing systems. 

We value demonstrated people leadership, sound judgment, and the ability to deliver through a team above any single technical specialization. A strong scientific or engineering foundation is essential, along with the curiosity and credibility to lead experts working on complex quantum systems. 

For candidates excited to make Chicago their next home, we are willing to provide relocation assistance for the right candidate. 

Role and Responsibilities 

This is a quantum hardware leadership and people-management role with technical oversight. You will be accountable for team performance, employee development, and execution at our new Chicago lab, while remaining close enough to the technical work to guide decisions and remove obstacles. Responsibilities may evolve as the effort grows, and the program needs to change. 

Lead the Chicago Quantum Systems Team, Guide Technical Development, and Deliver Results 

• Lead the hardware team launching Infleqtion’s Chicago quantum computer. Establish and maintain effective working practices and operational readiness, and reinforce Infleqtion’s culture of accountability, inclusion, scientific rigor, and open communication. 

• Manage up to six direct reports, setting clear expectations and providing regular feedback, performance management, coaching, and career development. 

• Help hire and onboard physicists and engineers, building a team with complementary strengths. 

• Represent the Chicago hardware team within Infleqtion and coordinate its work with the Chicago quantum software team and across the broader Computing organization. 

• Lead the team’s development, integration, commissioning, and operation of neutral-atom quantum computing systems, drawing on specialists’ expertise to guide technical decisions and improve processor performance, including gate fidelity, stability, availability, and reliability. 

• Ensure the team uses rigorous approaches to experimentation, validation, troubleshooting, and system operation. 

• Contribute to technical roadmaps, proposals, intellectual property, and external technical discussions. 

• Participate directly in technical problem-solving when needed, while maintaining primary focus on leading and developing the team. 

• Work closely with project managers to translate program goals into clear priorities, achievable milestones, staffing needs, and coordinated work plans; identify and track risks and resolve obstacles.
