Role Overview
Role:
We are looking for a HIL (hardware-in-the-loop) Test Manager to build and lead the team that owns our hardware test infrastructure: the systems our quantum-computer control software is tested on before it ever touches a real quantum system.
Every software and science change is validated against shared test systems before it reaches a quantum computer. We are now investing in the next generation of these: representative QA systems for fast feedback, and staging systems as close to a production quantum system as possible, with all the real-time and non-real-time hardware. You will define these systems, build them with our manufacturing team, and own them through their life: maintenance, upgrades to each programme baseline, and availability to the teams that depend on them.
This is a build-from-scratch role with budget and rack space already allocated. You will also act as our test architect: we have deep physics and engineering expertise, and you will bring the formal software-testing experience to shape what gets tested where (simulation versus real hardware) and how testing gates releases. You will start with one engineer hire alongside you and grow the team deliberately, turning the test estate into a reliable service the engineering teams depend on.
Responsibilities:
You will own the hardware test estate end to end and define how it is used. That includes making the estate self-service, with clear reservation and scheduling, published state and availability, and runbooks. Teams own their tests and what they gate on; your team owns the rigs and the plumbing.
You will hire, develop and lead a small team, starting with a hardware-focused test systems engineer, and work across the business with the wider Quantum System Infrastructure (QSI) teams, Compute IT, Facilities, Manufacturing, Software and Science.
Key responsibilities include:
- Own the hardware test estate: today's CI systems through to the new QA and staging systems for our current and future quantum-computer programmes.
- Define the test-system architecture: which systems exist, what each one represents, and how teams use them.
- Plan and deliver new test-system builds with Manufacturing, and own ongoing maintenance and upgrades so every test system tracks its programme's current baseline.
- Shape the testing strategy with the software teams: what runs in simulation or against emulators, what requires real hardware, and how hardware-in-the-loop results gate releases.
- Drive automation throughout: provisioning, firmware flashing, recovery and configuration of test systems as code, not manual effort.
Requirements:
We are looking for an experienced test leader who can bring structure, ownership and pace to how we validate software against real hardware. We treat QA and test as one discipline. You will have a working knowledge of modern CI/CD (GitHub Actions or comparable) and an automation-first instinct: repeatable and reliable over manual and heroic. You will be able to guide and review test-automation development in Python or similar; you direct the code, you do not have to be its main author.
These systems serve many teams, so strong collaboration and low ego matter: you will need to bring people with you as ownership and ways of working evolve. You will be comfortable with ambiguity and building from scratch in a fast-moving technical environment. Experience in quantum computing is not required. Experience with complex hardware and software systems or similarly demanding engineering environments is an advantage.
You’d be a great fit with:
- A strong software testing and QA background covering test strategy, test infrastructure and continuous integration. This is the core requirement.
- Experience owning test infrastructure where software is validated against real hardware, for example network and security appliances, autonomous vehicles, drones or defence systems, robotics, or other embedded products.
- Test-architecture capability: designing representative test environments, deciding what to test where, and balancing simulation against hardware-in-the-loop.
- Practical understanding of the pitfalls of testing with hardware in the loop, such as flaky devices, contention for rigs and environment drift. Deep hands-on electronics skills are not required.
- Experience leading or building a small testing team or function.
Compensation will vary based on individual factors such as education, qualifications, and experience of the final candidate(s), specific office location, and calibration against relevant market data and internal team equity. Posted base salary figures are subject to change as new market data becomes available. Our benefits include comprehensive medical, dental, and vision plans, matching 401(k), unlimited PTO and paid holidays, parental/adoption leave, legal insurance, and a home technology stipend. Details of participation in these benefit plans will be provided when a candidate receives an offer of employment.
At IonQ, we believe in fair treatment, access, opportunity, and advancement for all while striving to identify and eliminate barriers. We empower employees to thrive by fostering a culture of autonomy, productivity, and respect. We are dedicated to creating an environment where individuals can feel welcomed, respected, supported, and valued.
We are committed to equity and justice. We welcome different voices and viewpoints and do not discriminate on the basis of race, religion, ancestry, physical and/or mental disability, medical condition, genetic information, marital status, sex, gender, gender identity, gender expression, transgender status, age, sexual orientation, military or veteran status, or any other basis protected by law. We are proud to be an Equal Employment Opportunity employer.
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.
