Do you have a passion for quality and automation and do you get energy from signaling problems in time? Are you always looking for ways to improve quality and automate testing, integration and delivery?

As a Tester you help to test our in-house software platform Vertex. You will also have the opportunity to help design, build and maintain automated testing and the CI/CD pipeline, using the latest technologies. You are part of a team of software and data experts and you can be deployed on different and diverse projects at our customers. With your analytical skills you ensure that problems in the software end up in your hands instead of the customer.


Working at Energy Essentials should be fun and we do not have strict job profiles. The activities are primarily organized around the talents of our employees and the roles we play in various projects. In this way we bring out the best in people and we continue to learn from each other, previous experiences and new insights.

You will help us build and design the new energy transaction platform of the future Vertex. With Vertex, market parties can facilitate the transition within the energy market and set up complex processes. For example, Vertex offers solutions to support and automate processes such as strategic purchasing, delivery, pricing, back testing, messaging, balance maintenance and invoicing. This improves decisions through insight and algorithms (dashboards & trading). Vertex can organize data in such a way that it can be used for smart solutions (decision models) whether or not automated, such as controlling and optimizing sustainable means of production and/or consumption (including windmills, solar parks and batteries or algo trading) or setting up of dashboards for human decision making. Security, business rules, traceability and availability are essential here.
