Quantum IC Design Engineer

Berkeley, CA
Fabrication – Fabrication
Full-time
As a Quantum IC Design Engineer, you will drive systematic improvements to Rigetti Computing’s quantum processors through modeling and design. You will be actively involved in realizing the chips that are at the core of our technology stack. You will contribute to our quantum hardware simulation tools and use them to model the classical and quantum dynamics of superconducting circuits. You will lay out and design multi-qubit circuits for fabrication and develop next-generation quantum processors.

Key Responsibilities:

    • Design, lay out, and simulate quantum processors
    • Build CAD models of circuits and simulate them using commercial software (HFSS) 
    • Use custom simulation tools (Julia) to perform quantum analysis
    • Collaborate with fabrication and experimental teams to determine different circuit architectures to fabricate and measure 

Preferred Qualifications:

    • Formal mathematical skills, specifically linear algebra and analysis
    • Software engineering experience (Python, Julia is a plus)
    • BS or BASc in Physics/Computer Science/Electrical Engineering or related field
    • Excellent written and verbal communication skills
    • Ability to collaborate across diverse teams of expert engineers
    • Understanding of quantum mechanics, preferably including circuit quantum electrodynamics
    • Knowledge of computational modeling, in particular of quantum circuits, integrated or lumped element electrical circuit
    • Demonstrated contributions to open source software 
    • Experience using commercial EM solvers (HFSS, COMSOL, CST)
    • Research and/or industry experience
    • Understanding of semiconductor fabrication processes
    • Curiosity
About Rigetti
Rigetti Computing is on a mission to build the world’s most powerful computers. Based in Berkeley and Fremont, CA, we are scientists, engineers, builders, and visionaries who believe quantum computing is going to significantly affect health care, how we treat disease, how we generate energy, and how we feed humanity. We design and fabricate quantum circuits and deploy them as quantum computers available online. Our engineers build the full stack of technologies that are integrated into these machines, including cryogenic hardware and microwave circuitry, advanced analog and digital control modules, and a software stack that provides the world’s most advanced SDK and runtime environment for quantum computers. Our quantum computer is available through Our product, Quantum Cloud Services, which is the world’s first full-stack programming and execution environment for quantum/classical computing. We were founded by Chad Rigetti in 2013, and today employ over 140 people.
