Job Summary

As a Microwave Engineer in the quantum integrated circuit design team you will drive systematic improvements to Rigetti Computings 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 full-wave electromagnetic simulation workflow and use it to model the performance of superconducting circuits. Drawing from your expertise in full-wave radio-frequency engineering from fundamental theory through practical application you will identify and implement improvements to the integrated circuit layout to mitigate loss and crosstalk channels. You will lay out and design microwave multi-qubit circuits for fabrication and develop next-generation quantum processors.

Key Responsibilities

Design lay out and simulate superconducting microwave integrated circuits for quantum processors with a focus on optimal on-chip signal delivery (routing filtering multiplexing etc)
Simulate the full-wave electromagnetic performance of quantum processors (eigenmode & driven analyses) using commercial finite element software engineering the mode profile of resonant structures and the coupling between these resonant structures and on-chip feedlines to optimize device performance
Interpret simulation and experimental results to identify and mitigate unexpected loss and crosstalk channels or other undesirable microwave properties of the circuit
Collaborate with fabrication and experimental teams to determine different circuit architectures to fabricate and measure

Preferred Qualifications

PhD in Physics Applied Physics Electrical Engineering or a related field or the equivalent experience in industry
Demonstrated experience with microwave engineering in theory simulation and practice including the design and simulation of resonant structures and waveguides
Experience using commercial electromagnetic solvers (HFSS COMSOL CST)
Formal mathematical skills specifically linear algebra and numerical methods
Programming skills in Python for scientific applications ideally in industry or a highly collaborative environment
Excellent written and verbal communication skills
Ability to excel in a collaborative environment

Nice to Have

Experience with 2D CAD tools for integrated circuit layout and the GDS file format
Experience with gdspy or similar for automated circuit layout
Understanding of quantum mechanics potentially even circuit quantum electrodynamics
Demonstrated contributions to open source software
Understanding of semiconductor fabrication processes
Experience in a technical role within an industry or startup environment

$145000 - $175000 a year
