Senior Python Developer

Functie omschrijving
Flexible working and the possibility to work partly from home. That is what you can expect as a Senior Python Developer at Stedin! In this role, you combine technically challenging work with social impact and you play an active role in coaching, guiding and developing the other developers within the team.

The energy transition demands a lot from our electricity grid. As a Senior Python Developer at Stedin, you work on the further development of the Flex Toolkit. This innovative tool helps to optimally use grid capacity by calculating accurate capacity calculations and flexible contract forms. This increases insight, improves decision-making and prevents congestion.

You work together with different teams, collect user feedback through workshops and contribute to an Agile working environment. You also ensure the integration of Flex Tookit with systems such as PowerFactory, Setiam and SAP, to guarantee seamless operation.

De opdrachtgever(s)
Een goed team. Daar hoor je bij.

From day one, you will be part of the Agile Release Train (ART) Forecasting & Capacity Management. The team currently consists of a Product Owner, a Scrum Master, a Business Analyst, and 3 Developers. The team has a lot of freedom in its approach within the architectural frameworks. You will work closely with other teams and systems needed for the entire maintenance process.

What binds us? The drive to puzzle and come up with the best solutions together. To promote transparency and collaboration, we at Stedin work with a 'Big Room Planning'. This is a two-day meeting based on (Agile) SAFe that takes place every quarter. Colleagues from IT and the business come together during these two full and enjoyable days to determine what will be developed in the coming quarter.
