 Are you only satisfied when everything goes perfectly?
Are you enthusiastic, eager to learn and do you like variety?

Yep, this is exactly what I’m looking for!

Then read on, dear

Software Testing Engineer

because we have something in store for you!

Onyx One is the online platform that enables the registration, qualification and training of contractors working for large industrial clients.

It is a contractor management system with focus on safety and compliance.

Onyx is an SME with ambition. We work together with the largest companies and we are rightly proud of that!

You, as a Software Testing Engineer, contribute to the error-free operation of Onyx One. You analyze the specifications, make a risk analysis and select the most appropriate test techniques. You provide the setup of the test environments with the necessary test scripts and test data. In addition, you also write automatic test scripts yourself. You are responsible for the test analysis, test execution, evaluation and documentation of test results and reports.

Oops, I don’t have that experience! What now?

Don’t worry, we are also happy to talk to you if you have just graduated or have gained experience in another domain. Provided of course that you are open to learn a lot and quickly! And that you have an affinity with and interest in software in general and testing in particular.

Not the biggest team, but the best.

Do you like working in a relatively small team? Then Onyx is your spot! Together with Shu-Hsiang (Tommy for friends), Lennert (Lennert for friends) and Tim (Timmy for friends) and some off-shore colleagues, you examine our software. You leave nothing to chance.

It is a very varied job, where no day is the same. In addition to intensive contact with your teammates, you often work together with your colleagues from R&D and implementation & support.
