Job ID: 1753
The Role:
At scale, quantum computers will be integrated into classical datacenters — combining the unique strengths of CPUs, GPUs, and QPUs will help us solve the world’s hardest problems. We’re building a cloud service that lets customers combine quantum and classical computation seamlessly, where the classical can be either general-purpose or high-performance computing (HPC). As a Senior Staff Software Engineer leading our hybrid execution efforts, you’ll define and build the platform that makes hybrid quantum-classical workloads easy to write, extend, and run in production.
Responsibilities:
- Lead the design and delivery of our Hosted Hybrid Service, partnering closely with product management to define the product and validate it
- Define the execution model for the hybrid service — how quantum-classical workloads are defined, how they can be extended, and how customers specify HPC computation when it’s needed
- Drive the infrastructure strategy for the classical compute — both HPC and non-HPC — that backs hybrid jobs, in partnership with our cloud infrastructure team
- Build and maintain a library of reusable quantum workloads for customers and internal teams to build on
- Establish best practices for code development, quality assurance, documentation, and continuous integration and deployment
- Collaborate across HPC, Cloud, and Product teams, and communicate with executive leadership
- Mentor junior staff members; we’ll ultimately be building a team around you!
You’d be a good fit with:
- Bachelor’s degree in Computer Science, IT, or equivalent practical experience -- untraditional backgrounds are welcome and encouraged!
- Demonstrated experience as a technical lead, with the ability to deliver projects in a dynamic and ambiguous environment
- 10+ years experience in software engineering
- Experience designing, building, and operating cloud-hosted services or APIs that external customers depend on
- Familiarity with containerization technologies such as Docker and container orchestration platforms like Kubernetes
- Experience defining extensible service or function models (e.g. plugin architectures or function-as-a-service)
- Experience designing developer-facing libraries or SDKs used by external customers
You’d be a great fit with:
- 15+ years experience in software engineering
- Experience with hybrid quantum-classical computing frameworks or quantum SDKs
- Experience integrating cloud services with HPC infrastructure
- Exposure to quantum physics and/or quantum information science

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
US Non-Technical Jobs. Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
