Software Tester

Let’s shape the future of finance - together

At Isabel, we believe that real innovation happens when people and ideas connect 

That’s why we’re building more than technology, we’re building an ecosystem. 

One where every voice counts, and where your work can truly make a difference. 

We’re looking for curious minds and collaborative builders. People who believe success means growing together, learning from each other, and challenging the status quo.

If that sounds like you, keep reading. 

As a Software Tester you’ll join the Kube team (applications for verified corporate data, e.g. KYC/AML and ESG) and will design and execute test protocols to ensure our software products meet functional, performance, and compliance requirements. You work independently within established QA frameworks, collaborate with cross-functional teams, and contribute to continuous improvement of testing practices and product quality.

What you’ll do

• Review software specifications and controls in collaboration with Product and Development teams to ensure testability and clarity

• Guarantee expected behavior as described in the acceptance criteria

• Evaluate and maintain proper test scope from an acceptance point of view

• Analyze test results, identify defects, and provide actionable feedback to development teams based on clearly documented facts

• Ensure testing activities comply with internal risk frameworks and external regulatory requirements

• Contribute to the continuous improvement of QA processes, tools, and documentation

• Present test findings and recommendations clearly to stakeholders, supporting informed decision-making

• In an active changing environment related to priorities, be flexible while being transparent on (potential) impact

What makes you a great fit 

The Role requires comfort with ambiguity and the ability to adapt quickly to changing needs & requirements. As the pace is high, expect to be context switching a lot. The hard part is aligning with multiple stakeholders and getting to the best compromise, so it’s key to get things clear and push towards decisions.

• If you like complexity, you’ll love it here

• If you don’t like stakeholder management, you’ll get confused and won’t be able to deliver

• If you need a lot of babysitting to get the job done, you’ll hate it here
