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.
