Team

You'll work in a Scrum team of four to six members formed mostly by Python developers with a passion for data. The team is managed by a Team Lead. The Teams backlog is cured by the Product Owner and the Scrum Master. Your team works closely together with Business Analysts and a team of Data Scientists, providing them with data structures they can easily use to support company decisions.

A day at the office

After your morning Scrum standup, Rafael sends you a Pull Request to speed up the transfer of data from the ERP system using a new messaging system. You review it together and then merge the code. After that, you join David, the Product Owner, who wants to discuss and design a new architecture for providing insights about Customer Service costs to the Finance department. Just before lunch, you pass by Andres, a data scientist who is working on a new Machine Learning algorithm which can forecast warehouse stock. You help him moving some data to BigQuery. You invite him to have lunch together with your team. On the way back, you share your concerns about the Google Adwords ingest process with David. It's losing records, so you want to refactor some of the python code. You add a few automated tests, send the Pull Request to your teammate, Dirk, for review and at 16:30, the improvements are automatically deployed via our continuous integration pipeline. By 17:30, you're done for the day and, together with your team members, head to the bar for a drink.
