Staff Quality Engineer

Responsibilities

Own acceptance and non-regression evidence for the delivered quantum system: complete and harden the acceptance test suite for the first customer delivery, run in-house dry runs before each software delivery, and produce test reports for provisional acceptance, service verification and periodic non-regression, in the customer’s format
Maintain requirements-to-test traceability for contractual commitments, and contribute the test and verification sections of the Quality Assurance Plan
Turn this work into a repeatable acceptance framework for future deliveries, customers and sites
Build system-level test automation: end-to-end and API tests on the job execution stack (submission, lifecycle, results, errors, quotas) across simulator, emulated and real-hardware backends, plus end-to-end tests on our web interfaces
Run hardware-in-the-loop tests on our in-house systems, and build shared test tooling (fixtures, environments, test data, flaky-test management, CI integration)
Make the system-level suites usable as release gates, complementing the developers’ own tests
Set quality standards for the firmware production lane: release criteria, merge and release gates that apply whether the code is written by a human or an AI agent, and the bug lifecycle for customer systems (intake, triage, severity scale)
Make quality visible through metrics (escaped defects, flakiness, time-to-detect), and coach developers across teams on testing practices and testability, especially in a context of AI-assisted development
Bring the quality and verifiability perspective into department-level initiatives and design reviews, and turn specifications into acceptance criteria with the product owner before implementation

Requirements

8+ years in software engineering, including 4+ years focused on test automation or quality engineering with a cross-team or organisation-wide remit
Strong Python, and the ability to read and contribute to production code, not only test code
Proven experience building automated test suites from scratch for APIs and distributed systems (API/contract, integration, end-to-end) and integrating them as CI gates (GitLab CI or equivalent)
Experience producing formal test evidence and reports for external customers (acceptance, service verification, non-regression), with rigor and traceability
Experience testing systems with a hardware or physical component (hardware-in-the-loop, instruments, embedded or lab systems)
A track record of setting quality standards across several teams and getting them adopted through influence, not authority
Master’s degree or engineering school (Bac+5) in Computer Science, Software Engineering or a related field, or equivalent experience
Proficient English and excellent written and verbal communication; professional proficiency in French strongly preferred, as our first customer site works in French
Nice to have :
Web end-to-end testing (Playwright or equivalent)
Observability and non-functional testing (monitoring and alerting verification, load and stability testing)
Familiarity with AI-assisted development and the testing challenges it raises
Interest in quantum computing, and the ability to reason about circuit results and benchmark metrics
Experience on a product delivered to external customers under contractual quality commitments
