Test Engineer

Project overview

Hello Senior Test Engineer!

Do you want to work at the heart of the energy transition?

32 - 40 hours | Amersfoort / Hybrid (Mon+Wed) | Energy Market / IT | Start July 13, 2026 | Duration at least until the end of the year

Interviews: July 6 and 8 |

As a Test Engineer at EDSN, you ensure qualitative software that accelerates the energy transition. With your expertise in testing, software development, and test automation, you directly contribute to the reliability of our software and the sustainability of the Netherlands.

This is how you work as a Test Engineer full of energy

In your role as Test Engineer, you work within the System Team to continuously deliver new features with high quality. You are involved from the refinement stage and contribute to the test approach, scenarios, and automation. You understand that errors in our systems have a direct impact on the electricity grid, which is why your work is of great importance. The system team develops current standards, including RobotFramework, alongside innovative standards for test automation, release management, and assurance.

You have a background in software development and are strong in test automation. You work closely with developers to review code, build test scenarios, and seamlessly integrate them into CI/CD pipelines and GitOps workflows. Because our systems deal with large-scale, real-time data streams, your focus is also strongly on testing robust backend connections and asynchronous processes. Additionally, you coach your team in the areas of quality and test strategy.

You actively participate in the test community within EDSN, where Test Engineers from all teams come together to share knowledge, discuss new developments, and continuously improve.
