Electrical Engineer, RF Signal Delivery at Rigetti in Berkeley, CA

As an Electrical Engineer on the Rigetti Cryo-RF team you will design, build, and validate hardware that forms the signal chain for control and readout of our quantum computing system, from room temperature to the milli-kelvin cryogenic vacuum environment where the superconducting qubits operate. This involves design of printed circuit boards (PCBs) and selection of components for DC and RF signals up to 10 GHz, selection of materials and fabrication processes to balance competing electrical and thermal conductivity requirements, and working with component manufacturers, PCB fabrication suppliers, and electronic assemblers to ensure that manufactured components perform reliably as intended. You will be working closely with a team of electrical engineers, mechanical engineers, and physicists to define system and component requirements, and integrate your designs into functional customer-deployed quantum computers.

As scientific and engineering leaders, we value diversity and are committed to building a culture of inclusion to attract and engage innovative thinkers. Our technology, meant to serve all of humanity, cannot succeed if those who built it do not mirror the diversity of the communities we serve. Applications from women, minorities, and other under represented groups are strongly encouraged.

Preferred Qualifications:

• Experienced user of electrical CAD software for schematic and layout design (Altium preferred).
• Understanding of design requirements for performance of RF analog signal routing, including impedance control and crosstalk mitigation.
