Senior Software Engineer, Automation and Calibration

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.


We're looking for engineers who bring fresh ideas from all areas, including distributed computing, embedded systems, large-scale system design, networking and data storage, security, artificial intelligence, scientific computing—the list goes on. As a software engineer, you’ll help build our next-generation quantum computer operating system, with opportunities to switch projects as you and our business grow and evolve. We need enthusiastic, versatile, collaborative engineers to take on new problems across the stack as we continue to push quantum technology forward.

IonQ reflects the globally diverse audience that our products and technology serve. We believe that in addition to hiring the best talent, a diversity of perspectives, ideas, and cultures leads to the creation of better products and services. IonQ is and always will be an engineering company. We hire people with a broad set of technical skills who are ready to take on some of humanity’s greatest challenges and make an impact on millions, if not billions, of users.

Improving the quality and optimizing the efficiency of our quantum computers requires developing control routines and automated calibrations with our team of experimental physicist operators, and helping configure new hardware for the system. Prior experience with control theory, hardware device control, and working with scientists will be helpful; data analysis and statistical methods are even more useful.

This is an opportunity for a senior software engineer with an emerging or existing interest in quantum computing to bring their diverse background and talents into the future. Alternatively this is an opportunity for a quantum researcher with strong software engineering skills to engage in bringing quantum computers from the lab to the cloud. We’d love a blend of hands-on experience as well as tactical and strategic direction.

In your first three months, you’ll be helping bring up and support our newest quantum computers.
