Vacature

Werk waar je trots op kan zijn
Dit ga je doen

Flexible working with a good salary and the possibility to work (partly) from home. That is what you can expect as a Senior Python Developer at Stedin!

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.

How does your day as a Python Web Application Developer at Stedin look like?
After a delicious cup of coffee (or tea) that you order in sign language from our hearing-impaired 'barista', you start the day with the daily standup. Together with your colleagues, you discuss the priorities and obstacles, after which everyone gets to work.

At the start of each sprint, you review the goals for the coming two weeks with the DevOps team and the Product Owner. You support your team and vice versa, in order to maximize the product value. One day you plan or refine, the next day you are focusing on agreed tasks. During the planning, you test whether the work is realistic or needs to be revised.

At the end of the morning you complete a number of introductory meetings. The information in these meetings is crucial for you need to understand the business context of the application and to further develop your knowledge. After these meetings you coordinate integrations and user stories in short online meetings with other DevOps teams. Finally, you work with a colleague on a low-level design for a congestion solution.

Time for lunch! You can have lunch on the 18th floor with a magnificent view of Rotterdam, with your own lunch or something fresh from the company restaurant. Or you can take a walk in the city. Time to get back to work. In the afternoon there is a refinement on the agenda: here we determine the steps for the delivery of user stories for the coming quarter every week.

You round off the day by coordinating with the Epic Owner what the next step is in product development. You also check the ticket system to see if you can pick up a few management requests. And at the end of your workday you are in a few steps at Blaak station, so you are back home quickly!

You are an enthusiastic and inspiring colleague who enjoys working on new product development within a constantly changing and technically challenging playing field. With your motivational approach, you stimulate the growth of your fellow developers, help them to use their potential and actively contribute to a learning-oriented and supportive working environment.

Thanks to your strong communication skills, you work effectively within the team and create a culture of continuous improvement: for yourself, your colleagues and the customer.

Good to know: At Stedin we have plenty to do. That is why this role is available for a minimum of 32 hours. Want to get even more out of your role? Of course, working 40 hours is also possible.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.Mooie arbeidsvoorwaarden

Die wil je hebben

It's quite obvious to us that you get your own phone (or a Bring Your Own Device allowance) and laptop from us. What else can you expect from Stedin as an employer?

All financial employment conditions at a glance, so you know exactly where you stand:
  • Good employment conditions are part of the deal. For example, you get a (maximum) salary of € 5.500 based on 40 hours per week and your knowledge and experience, 24.5 vacation days, and you build up a good pension with the ABP.
  • 24% personal budget on top of your salary (incl. vacation pay). This means a maximum of € 880 (excl. 8% vacation pay) extra salary per month or 35.5 extra vacation days per year. In our new Calculation Tool you will get a preview of what your personal budget could look like and how you could spend it.
  • You need healthy energy. That's why you also get a Sustainable Employability budget of €500 gross per year from us (for example, for your gym membership, an exercise bike, or your new sports outfit).
  • According to our Stedin@Work concept, you work 50% from home and 50% at the office, which is quite flexible. We take care of your home office facilities, a home working allowance, and you travel to the office with your free public transport subscription, which also allows you to travel unlimited outside of work!
On top of that:
  • Working at Stedin means working at a World-class Workplace. One of the points of pride of our (and your future) colleagues? The work atmosphere!
  • Your development is central: attending events with colleagues, participating in knowledge sessions, following training courses and education. This way, we really give your talent every chance and you get the best out of yourself.
  • Good coffee from Heilige Boontjes.

arbeidsvoorwaardenArbeidsvoorwaarden
Elke maand je Persoonlijk Budget kiezen

Het Persoonlijk Budget is een percentage van je bruto maandsalaris en ontvang je bovenop je salaris. Afhankelijk van je salarisschaal is dat tot 24% van je brutosalaris, inclusief 8% vakantiegeld. Je bepaalt zelf waaraan je het Persoonlijk Budget wilt besteden. Zo kun je het uit laten keren voor een maandelijks extraatje. Of je koopt extra verlofdagen.
Flexibele werktijden

Wil je zelf je werkweek indelen? Samen met je leidinggevende bepaal jij zo veel mogelijk je eigen werktijden. We werken 8 uur per dag. Afhankelijk van je werkzaamheden, heb je de mogelijkheid om, wanneer het kan, thuis te werken.

Vervoer

Bij Stedin werken we elke dag aan de energietransitie. Dat doen we bij klanten, op kantoor, thuis of in de put. Onze werkzaamheden en functies zijn heel verschillend. Daardoor hebben we ook verschillende reisbehoeften. Voor sommige functies krijg je een 100% elektrische bedrijfsauto of -bus. In andere functies kan je kiezen voor een OV-kaart die je ook in je vrije tijd mag gebruiken. Wissel je liever af? Kies dan voor flexibel reizen met eigen vervoer, OV en een extra netto vergoeding voor de fiets. Stap je op de fiets dan ontvang je 33 cent netto per kilometer, met de auto is dat 23 cent. Voor zakelijke reizen kun je gebruik maken van een deelauto, die zijn natuurlijk ook 100% elektrisch. Nu reageren

Laten zien wat je in huis hebt

Interested in this job where you are at the forefront of the energy transition? Plenty to do at Stedin! Are you joining us? You can do so by clicking the 'apply' button, sending your CV and cover letter. We are looking forward to meet you!

Whoever you are, whatever you do, you are welcome with us. Because if you are yourself, things work just that little bit better.

Thanks to a (pre) employment screening and an assessment, we can get to know you (and you yourself) even better. That is why these are part of the selection procedure.

Finding a mutual match, that is what gives us new energy! That is why our vacancies are not a call for acquisition, we like to recruit our new colleagues ourselves.Solliciteren
