Test Automation Engineer

Wat ga je doen?

For this role you need to live in The Netherlands already and preferably speak Dutch or A2 level at least, and English fluently.

The team is responsible for all technology regarding Data and Media on our Mobile and fixed platforms. In these teams you are always in touch with the latest innovations and technology in the media domain. When our streaming or TV service introduces a new feature, the team need to sit down with the suppliers of these services to ensure proper integration and validation into our T-Mobile services. Testing is currently done “old-school”, so mostly manually. But we are eager to automate this entire test process as far as possible, end to end. From functional to system, as much as possible in automated scripts.

So when you are an experienced test engineer, with 5 to 7+ years’ experience, not only technically capable of having the overview of all challenges ahead, creating the test automation scripts, keeping your stakeholders close, being inspirational, cooperative yet knowing what needs to be done, in a “Test automation”  greenfield, you certainly have our attention! We hope we have yours too!

Waar kom je te werken?

The Test Automation Engineer within the Data and Media Design team takes a central role in the validation of all media ecosystem components (software, integration layers, appliances, client applications etc.) in the chain from content supplier providing the TV channels and media assets to the customer consuming them. As such, the Test Automation Engineer understands the functional and non-functional requirements of these various ecosystem components and takes the lead in developing test cases and test plans, selecting test frameworks and methodologies and building and maintaining the test infrastructure. Tests are executed (where possible automated and ran periodically / continuously). Test results are reported to the relevant stakeholders (e.g. internal developers, external suppliers) in a clear and concise manner. Defects are logged and tracked.

Wat breng je mee?

  • Bachelor or Master in Any computer related study, or for example Media Design or related.
  • Minimum of 5 years’ experience within Quality (Test) engineering, including all necessary certificates like T-Map etc.
  • Experience with testing APIs and services using REST, SOAP, etc.
  • Experience with source control systems (git).
  • Fluency in at least some programming/scripting languages used for test automation (shell command languages, python, php, perl etc.).
  • Fluent in English, both written and spoken.

Desired skills, yet not “mandatory”, we can always support you in training 😉

  • Experience with integrating test automation scripts in CI/CD tools.
  • Experience with test automation tools, such as SoapUI, Cucumber, Selenium/Appium, Robot Framework
  • Understanding of common programming languages, preferably C#, Javascript but Java will also do!

Wat bieden we jou?
