The function

Zarafa is looking for a hands-on Technical Software Tester to strengthen our Quality Assurance Team in Delft, The Netherlands.
Your tasks cover a broad area of testing activities and you use modern tools, systems and techniques. You are familiar with best-practices such as Continuous Integration and Scrum and seek the best possibility to achieve the highest quality possible.

As a Technical Software Tester you not only take an active role in the Zarafa Quality Assurance team, but you also assist the support desk with analyzing customer-related issues and setting up reproducible test environments. These systems are all based on Linux; having experience with Linux systems is therefore a must.

You act as test guardian for our international development teams in India, Brazil and elsewhere. You understand the importance of user requirements and specification by example. You seek opportunities to improve the software quality by implementing and maintaining automated testing tools in our Continuous Delivery Pipeline.

The product

The Zarafa WebApp is the latest addition to our product suite, the new generation groupware software (single page web application) which will replace desktop clients. The Zarafa WebApp relies heavily on the backend which is the Zarafa Collaboration Platform. By adopting open standards, Zarafa strives to become the best platform for collaboration and sharing.

What makes this role so unique?

As a young, dynamic and rapidly growing company, the Zarafa brand has acquired quite an international following. We work worldwide with Linux engineers and developers from many leading (open source) organizations. Even more exciting is that many longtime Linux gurus and well-known specialists in the field are regularly in contact with us. Leveraged by this outside support, Zarafa continues to tackle common technology challenges, where external people come up with new solutions or contribute new testing on additional platforms. We are committed to test completely all of our releases before they are made available and rolled out at customer sites.

We at Zarafa foster a hands-on culture where we focus on end-to-end solutions rather than just solving low-level isolated problems. Zarafa has a non-hierarchical flat organization where the “individual” is key in influencing new product development. You feel proud that your contributions are being enjoyed by millions of people all over the world, and that many developers in different countries in different cultures speaking a multitude of languages provide feedback and expand on your efforts.

Why is this role so amazing?

  • You develop yourself further in a broad range of technical and non-technical aspects
  • You collaborate and exchange ideas with skilled colleagues and Linux experts at Zarafa and beyond
  • You influence software testing processes, automated (regression) testing
  • You take responsibility to setup and maintain our Continuous Delivery Pipeline
