Werk om trots op te zijn



As a Senior Python Developer, you contribute to the further development of the Flex Toolkit: an innovative application that optimises grid capacity through smart calculations and flexible contract options. Your work directly improves insight and decision-making which helps prevent congestion across the grid.



A day as a Senior Python Developer:

• You start your day at the office at the Blaak with the daily stand‑up, where you and your teammates align on priorities and support each other where needed.
• You develop and improve the Flex Toolkit and work on integrations with systems such as PowerFactory, Setiam and SAP.
• Then you realize it's already time for lunch. For this, you can head to the iconic Markthal or into the city with the rest of the team. If you prefer to stay inside, you can visit our company restaurant on the 18th floor with a beautiful view of Rotterdam.
• After the lunch you it's time to head back to work! During the sprint planning and refinements you actively share your perspective on feasibility, technical choices and priorities. You collaborate closely with other DevOps teams, translating business needs into clear, future‑proof technical solutions.
• At the end of the day, you align with the Epic Owner on next steps. It was a producttive day at the office and with a sense of satisfaction, you shut down your laptop and head home easily from the Blaak station. Tomorrow you will be working from home.
