FPGA Engineer Bothell, Washington

Watch IonQ's Quantum World Congress 2025 Keynote On Demand.

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 such as medicine, materials science, finance, artificial intelligence, machine learning, cryptography, and more.

IonQ is at the forefront of this technological revolution.

As a Staff FPGA Engineer, you will be part of a cross‑functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems. You will design complex FPGA solutions for our trapped‑ion quantum computer control systems, perform top‑level requirements definition, create system specifications, design, code and simulate, and contribute to the development of our automated build and verification process for an RTL CI/CD pipeline.

You will enjoy hands‑on lab work, collaborate with a team, learn technical topics, work across multiple technical domains, and be uniquely positioned to help us reach the next horizon in quantum computing.
