• Lead and provide technical focus on specific R&D topics, including gate calibration, qubit relaxation/dephasing, piloting new research ideas, integration of innovations into large processors, or implementation of quantum error correction;
• Collaborate with cross-functional engineering teams (fabrication, design, electronics, software) to turn experimental concepts into robust, scalable technologies.
• Stay up to date with cutting-edge research, synthesize results from literature, and implement state-of-the-art calibration, error diagnostics, and system optimization techniques.

Qualifications:

• PhD in Physics or a similar applied scientific field, or Master’s in Physics with 2+ years of relevant industry experience.
• Proven abilities in experimental problem-solving and research.
• Expertise in implementing coherent quantum effects and control.
• Proficiency in Python for scientific applications;
• Strong collaboration skills with a team-first mindset.
• Excellent communication skills.

Preferred:

• Experience calibrating and characterizing single- and two-qubit gates in superconducting quantum devices.
• Experience with quantum simulation frameworks such as QuTip.
• Demonstrated ability to execute and communicate outcomes from innovative R&D initiatives.
• Software development experience in collaborative industry settings;
• Prior technical role in industrial or startup environments.

Benefits and Compensation:

• Base salary: $155,000 - $200,000 per year, determined by experience, skills, and location.
• Full benefits including medical, dental, and vision coverage.
• Equity opportunities and 401(k) plan.
• Paid parental leave and vacation policy in line with local regulations.
• Rejuvenation days to support work-life balance.
• Inclusive work culture promoting diversity and equity.

Other Information:

• Rigetti Computing is a pioneer in full-stack quantum computing with proprietary multi-chip quantum processors and in-house fabrication at Fab-1.
• Commitment to equal opportunity employment and diversity in hiring;
• AI tools may be used in parts of the hiring process, but final decisions are made by humans.
