Staff Software Engineer, Digital Signal Processing

Location: College Park, Maryland

Team: Software

Type: Full-Time

IonQ is developing the world's most powerful full-stack quantum computer based on trapped-ion technology. We are pushing past the limits of classical physics and current supercomputing technology to unlock a new era of computing. Quantum computing has the potential to impact every area of human society for the better. IonQ’s computers will soon redefine industries like medicine, materials science, finance, artificial intelligence, machine learning, cryptography, and more. IonQ is at the forefront of this technological revolution.


Our quantum computers perform calculations by shooting individual atoms floating in a vacuum with carefully modulated laser pulses—the better the pulse, the better the computation. We’re looking for a staff software engineer to help us make the best pulses on the planet. You’ll be part of a cross-functional team whose mission is to ensure we consistently deliver the best quantum gates in the world, helping drive the technical direction for our next-generation quantum computers.
