Senior QA Engineer

Permanent employee, Full-time · Luxembourg

Your mission

Do you want to join our rockstar team of innovators and make a REAL impact in the sustainability space?

Circu Li-ion is driving the green revolution by prolonging the lifespan of individual battery cells through our cutting-edge automated battery disassembly lines. Our systems disassemble Li-ion battery packs into reusable Li-ion cells, minimizing waste and maximizing sustainability. Our mission is to bring cost of re-using material down and enable true urban mining with robotics and smart software. The cheaper disassembly is, the closer we get to a real circular economy.

Your Role

We are looking for a highly skilled Senior QA Engineer to take full ownership of our testing stack, ensuring high-quality software and hardware releases. This role requires expertise in both manual and automated testing, along with a proactive approach to optimizing our QA processes. The ideal candidate is a quick learner, takes ownership of new tools and technologies, and continuously drives improvements in testing methodologies.

In addition to software testing, we work with robots (KUKA, ABB) and PLCs (Beckhoff). While prior experience with these systems is a plus, it is not required, what matters most is your ability to learn quickly and adapt to new tools.

Your Responsibilities

Oversee and manage the entire QA process, from integration testing to release validation and factory acceptance tests.
Design, implement, and execute comprehensive test plans, including both automated and manual test cases.
Enhance the testing stack by integrating modern tools and best practices.
Collaborate with Engineers, Product Managers, and other stakeholders to define and maintain quality standards.
Lead the development and maintenance of automated testing frameworks, primarily using Python.
Conduct end-to-end, regression, and exploratory testing as needed.
Continuously improve testing processes and frameworks to increase efficiency and effectiveness.
Quickly learn and take ownership of new testing tools and technologies, including those related to robotics and PLCs.
Document testing processes, identify gaps in existing documentation, and ensure clarity and consistency across QA workflows.
Stay updated on emerging testing tools, trends, and best practices to drive innovation in QA.

Your profile

Proven experience as a QA Engineer.
Strong understanding of software and hardware testing methodologies, tools, and processes.
Great autonomy. You should understand business requirements and define the process.
Proficiency in automated testing frameworks and scripting languages, with a strong focus on Python (e.g., PyTest, Selenium, Robot Framework).
Hands-on experience with test management tools (e.g., TestRail, Zephyr, Qase).
Familiarity with CI/CD pipelines and experience integrating testing into the development workflow.
Strong analytical skills to assess complex systems and design effective test strategies.
Excellent communication and collaboration skills.
Strong documentation skills, with the ability to clearly define testing processes and identify gaps in existing documentation.
