Your challenges

  • Implement and use the existing data pipelines and infrastructure that drive our internal reporting systems  as well as feed back into our production and machine learning systems.

  • Advance our software architecture and toolset to growing challenges and data amounts (performance, scaling, data quality)
  • Understand and communicate effectively with internal business customers, partners, and stakeholders



  • Have a quantitative background (B.Sc./M.Sc. in e.g. Math, Computer Science) and the data driven mindset and rigour that goes with this. And at least 4 years experience working with data heavy platforms.
  • Writing SQL and using the included advanced analytical functions come second nature to you
  • Working with a modern platform that ingests up to 10000 events per second combining technologies like Pub/Sub, BigQuery and BigTable (yes, that’s the Google Cloud) excites you
