Senior Test Infrastructure Engineer - Quantum Systems

IonQ, Inc.; Bothell (WA); Hybrid; USD 146,000 - 209,000; Full time

Job summary

IonQ, Inc. is seeking a Software Engineer - Test Infrastructure to join the Release Engineering team. You will own the quality signal for the software that runs IonQ's quantum computers, and design automated tests across hardware-software boundaries.

You will build and operate CI infrastructure, extend test coverage for operator-facing tooling, and collaborate with software, hardware, and physics teams to define robust test strategies for first-of-their-kind systems.

Qualifications

• 5+ years of professional experience in test infrastructure, software test automation, CI engineering, or a closely related field.
• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field, or equivalent practical experience.
• Strong programming skills in Python or another general-purpose language, with experience creating test frameworks and automation tooling.
• Hands-on background designing, operating, and scaling CI/CD systems that engineering teams depend on.
• Experience implementing system-level integration tests for complex, multi-component systems.
• Experience with hardware-in-the-loop or lab-based test environments, or demonstrated aptitude for working close to physical hardware.
• Excellent debugging skills, particularly across the boundary between software and hardware.
• Strong collaboration skills; this role works closely with engineers on multiple product teams.

Responsibilities

• Own end-to-end integration testing of our system software: design, develop, and maintain the automated test suites that validate complete quantum computing systems on shared test environments, including circuit execution under realistic customer workloads.
• Extend automated test coverage of operator-facing tooling and workflows, exercising the interfaces engineers and physicists use to operate and calibrate systems.
• Design, build, and operate the CI infrastructure that catches integration bugs before software is deployed onto systems, in partnership with software development teams - and keep it fast, reliable, and trusted.
• Define and evolve system-level test strategy: identify coverage gaps beyond functional job execution and build the tests and instrumentation to close them, including performance characterization and electronics-control validation where appropriate.
• Own integration-test triage and reporting: drive failures to root cause, attribute regressions to the responsible component, and deliver specific, actionable feedback to owning teams.
• Manage the lifecycle of the test system fleet across IonQ product lines: establish consistent hardware and software baselines across instances, coordinate upgrades and decommissioning with the product teams that define their requirements, and maintain an authoritative record of each system's configuration and fitness for purpose.
• Champion testability across component teams, promoting the interfaces, test hooks, and practices that make our system software easier to validate.
