Do you enjoy testing, know how to look at a product through the eyes of a user, and think critically about what could be done more efficiently? At Billdu, we are looking for someone who will primarily focus on manual testing, but who is also not afraid of automation, thinks systematically, and knows how to use AI tools where it makes sense.

We are not looking for someone who will just mechanically click through checklists. We are looking for someone who can think things through, ask the right questions, identify risks before they become problems, and while testing also think about what could be automated or improved in the future.

Our ideal combination is a strong manual tester with good product thinking, a technical mindset, and openness to AI and automation.

What would your job involve?

• Manually testing our products across both mobile apps and the web.

• Looking for bugs, UX shortcomings, unclear product behavior, and edge cases that others might miss.

• Designing test scenarios and thinking about what makes the most sense to test, in what order, and why.

• Collaborating with developers, product, and other team members so that issues are resolved quickly and sensibly.

• Helping set up and improve QA processes so that testing is not only reactive, but also sustainable in the long term.

• Looking at what could be automated over time and where automation would truly bring value.

• Using AI tools as a helper in testing, scenario creation, risk analysis, documentation, or improving efficiency.

Candidate requirements

• You have experience with manual testing of mobile apps.
