QA Engineer (Software and Hardware Integration QA)

As a Software & Hardware Integration QA Engineer, you will play a key role in ensuring the quality and reliability of Quandela's quantum computing systems

Your main focus will be on validating the integration between software and physical hardware: ensuring that our software interfaces correctly control, communicate with, and monitor equipment such as photon sources, laser control systems and other optical and electronic components

You will design and automate integration and end-to-end testing, while helping structure robust validation processes as Quandela moves from low-volume, highly complex systems toward more scalable and repeatable production

Working closely with software, hardware, systems and industrialization teams, you will contribute to building the testing methods, tools, documentation and quality standards required for this next stage of growth

Define QA plans, test strategies, acceptance criteria and validation procedures for software/hardware integrated systems

Design and execute functional, integration, system, regression and robustness tests on real equipment

Build automated software-to-hardware integration and end-to-end tests

Validate complete workflows, from software interfaces and commands to their execution by physical equipment

Test and troubleshoot communication between software and hardware through interfaces and protocols such as Ethernet and serial connections

Develop and maintain automated tests and test tools using Python and testing frameworks such as Behave, with reporting tools such as Allure

Integrate automated testing into continuous integration pipelines where relevant

Reproduce, document and track defects through resolution, verify fixes and assess regression risks

Maintain clear traceability between requirements, test cases, defects and test results

Produce test reports, quality metrics and technical documentation to support validation and release decisions

Help define and continuously improve industrial-grade validation processes, test procedures and quality practices

Build reusable and scalable testing methods to support the progressive ramp-up of Quandela's quantum computing systems

Collaborate closely with software, hardware, systems and industrialization engineers to improve overall product quality

Requirements

• Good communication skills and the ability to collaborate with multidisciplinary teams
• Experience with automated testing frameworks and reporting tools; experience with Behave and/or Allure is a plus
• Professional proficiency in English, both written and spoken
• Hands-on experience testing systems combining software and hardware
• Experience in industrial environments such as robotics, embedded systems, scientific instrumentation, photonics, semiconductor equipment, medical devices, automotive, aerospace or other complex hardware/software systems would be particularly relevant
• Knowledge of quality standards such as IEC 61508 or ISO 9001 would be appreciated but is not mandatory
• Ability to understand, test and troubleshoot hardware/software interactions and communication protocols
• Ability to produce clear and structured technical documentation
• Around 5 years of experience in software QA, system validation, verification & validation, test engineering or a similar role
• Strong experience with test automation and scripting, ideally using Python
• An interest in building and improving testing processes, rather than only executing existing test plans
• Strong analytical and problem-solving skills with attention to detail
• Experience working within structured software development and QA processes, including requirements traceability, documented testing, defect management and release validation
• An engineering degree or equivalent technical background is welcome, but we value relevant hands-on experience and demonstrated technical skills above all
