API Backend Developer - KPN.com (Python)

Your job as a API Backend Developer

The DDCI team is a small (English speaking)  team (around 7 people) that focusses on getting more relevant and personal offers to customers. You will work on getting such offers on a most effective way to all different touchpoints of KPN like Online, Apps, Customer Service systems, etc. These offers can consist of Sales campaigns but also real time information that is relevant on that time for a customer. This team acts as a bridge between the Big Data environment of KPN and the real time capabilities of it! We work agile, we work together (also with a lot of other teams) and we think in solutions.

As a Medior/ Senior Python Developer you, together with the team, are responsible for providing our user facing products with all the information they need to create an awesome user experience.  Your main focus will be providing as much relevant data as fast as possible for our user facing applications: mobile apps, online, CRM systems. For that, you'll integrate dozens of backend systems, caching where needed, and come up with solutions to guarantee high availability even when those systems are flaky.

Your responsibilities include:

• Development of api.kpn.com in the context of different business projects
• Ensuring the quality of your deliveries by using (and contributing to) our Continuous Integration / Continuous Delivery pipelines
• Ensuring your code reports key metrics about usage and performace  so that it can be extended in a controlled way

What do we expect from you

• You're more than good at Python; you're great at it! You wonder how people worked on IT before. Django is your framework of choice and you have broad experience with it. Git is your best friend; rebasing, pushing to your own fork and opening pull requests are everyday activities.
• You are capable of designing and implementing calls for an HTTP API in a high traffic environment; in fact, you're eager to prove it!
• You feel comfortable working in Unix based systems and speak fluent bash and curl. Your comfort zone doesn't end outside your editor's window. You understand how to work with a relational database (MySQL/PostgreSQL) outside of your favorite ORM
• Experience in frontend development and ETL/Informatica + basic knowledge in big data/ datascience makes you complete
• If you have to do something twice is annoying; three times means you automate it so that it doesn't bother you again. Your communication skills make you an appreciated team player. You are able to estimate complexity and communicate it to business stakeholders (mainly Product Owners). You work in an Agile way and are capable of delivering small and tested increments of a product while working towards a bigger picture
