Microwave Engineer, Quantum Processor

Job Description

Job Title: Microwave Engineer, Quantum Processor Microwave Design. Location: Berkeley, CA, USA

You will focus on superconducting circuits, full-wave electromagnetic simulation, and layout optimization to improve performance, reduce loss, and minimize crosstalk in next-generation quantum processors.

Duties:

• Design, lay out, and simulate superconducting microwave integrated circuits for quantum processors.
• Optimize on-chip signal delivery including routing, filtering, and multiplexing.
• Perform full-wave electromagnetic simulations using finite element tools to analyze resonant structures and coupling.
• Engineer mode profiles and feedline coupling to improve device performance;
• Analyze simulation and experimental data to identify and reduce loss, crosstalk, and unwanted microwave effects.
• Collaborate with fabrication and experimental teams to evaluate and select circuit architectures.
• Contribute to the design of multi-qubit microwave circuits for future quantum processors.

Qualifications:

• PhD in Physics, Applied Physics, Electrical Engineering, or a related field, or equivalent industry experience.
• Strong background in microwave engineering, including theory, simulation, and practical design.
• Experience with electromagnetic simulation tools such as HFSS, COMSOL, or CST.
• Solid mathematical foundation, including linear algebra and numerical methods;
• Programming experience in Python for scientific or engineering applications.
• Strong written and verbal communication skills.
• Ability to work effectively in a collaborative, cross-functional environment.

Nice to Have:

• Experience with 2D CAD tools for IC layout and the GDS file format.
• Familiarity with gdspy or similar tools for automated layout generation.
• Understanding of quantum mechanics or circuit quantum electrodynamics.
• Experience with semiconductor fabrication processes;
• Contributions to open source software or prior startup experience.

Benefits and Instructions:

• Base salary range: $145,000–$175,000 per year.
• Final compensation depends on experience, skills, and location.
• Benefits include equity, medical, dental, vision, 401(k), paid parental leave, rejuvenation days, and competitive vacation policy.
• Rigetti is an equal opportunity employer and encourages applications from underrepresented groups;
• AI tools may be used during parts of the hiring process, with final decisions made by humans.
• Apply directly to be considered or submit your profile for future opportunities if no current role fits.
