Cryogenic RF/Analog IC Design_Engineer

About QpiAI

QPiAI is one of the first quantum computing company from India. At QpiAI, we aim towards designing the full quantum computing stack along with integrating it with special-purpose optimization hardware and GPU accelerators. More information about us can be found at: https://qpiai.tech/

QpiAI Quantum hardware team is responsible for designing the Cryogenic Quantum Control Circuits, RF Control Hardware and QpiAI ASGP. As a Cryogenic IC Design and characterisation, you would be involved with designing the Analog/RF frontend for qubits control and readout that would operate at extreme low temperatures (~4 Kelvin).

Job Description

Role offers opportunity to work in scalable Quantum hardware development of both QpiAI RF control hardware for Quantum Computer.

Candidate will be part of the QpiAI Quantum Hardware team.

Requirements
