Test Automation Engineer
Brussels-Capital
Digital - Testing and QA
Work experience: 5-7
Reference number: 91678

We’re looking for two Senior Test Automation Engineers to join a team working on next-generation railway data solutions. You’ll help validate and safeguard the quality of systems that transform complex infrastructure datasets — lines, tracks, signals, switches and more — into a unified, graph-based platform used for real-time traffic planning and monitoring.

If you enjoy building reliable automated test suites, working closely with developers, and improving quality in a high-impact operational environment, this role is an excellent fit.

What You’ll Do

You take ownership across the full test automation cycle:

  • Design test scenarios based on business requirements, functional and technical analysis.
  • Estimate test effort and build automated test scripts for JavaFX clients, RESTful backends and Angular web interfaces.
  • Maintain test scripts in Git repositories and ensure optimal collaboration across the team.
  • Integrate automated tests into CI/CD pipelines (Jenkins, Azure DevOps).
  • Contribute to code reviews, documentation and knowledge sharing.
  • Prepare test reports across multiple environments (DEV, INT, TST, ACC, EDU, PROD).
  • Execute manual tests where automation is not yet available.
  • Log defects clearly and support developers in reproducing and resolving issues.

What are we looking for?

You bring senior-level testing experience in both UI and API layers, with hands-on skills in:

  • ISTQB CTFL certification (mandatory)
  • Testing fat-client applications (JavaFX) and web applications (Angular)
  • TestComplete + at least one other automation framework (Selenium, Cypress, etc.)
  • Postman for API testing
  • Programming in Python, C#, or Java
  • Linux, bash scripting and SQL
  • Git version control and CI/CD tools (Jenkins or Azure DevOps)
  • Working with XML, XSD, JSON, gRPC
  • Agile/Scrum delivery environments

Language requirements:

  • Fluent in Dutch or French (C2 level)
  • Good understanding of the other national language (B1 level)
  • Strong professional English (B2 level)

A relevant IT degree or equivalent expertise is expected.

What do we offer?

Location: Brussels (hybrid)

Contract: Freelance or Permanent

Start date: 01/02/2025

End date: 31/01/2031
