About Flowminder

Flowminder is a pioneering, internationally operating non-profit organisation that supports disaster relief and development efforts through several products including the analysis of data gained from mobile phones and household surveys in privacy and security preserving manners.

  • Be familiar with the processes at each stage along a data pipeline.

  • Understand the typical transformations (intermediate tables, aggregations etc) performed on data and how they can be done efficiently.
  • Understand what is involved in integrating our application's data output with the dashboards of 3rd party applications.
  • Be able to break down applications into individual services.
  • Be familiar with containerisation (especially Docker).
  • Have a good working knowledge of APIs (their use and development) and understand what it’s like to develop on both sides.
  • Have experience supplying metrics about the performance of an installed application.
  • Implement best practice around security and data privacy 
  • Be fluent in English including in a technical environment.  French/Portuguese would be a bonus.
