Senior Machine Learning Engineer at at Rainbow Weather (Warsaw/Hybrid or Eu/Remote)

We are a start-up called "Weather Forecast Technologies -" and we are building the most accurate weather service in the world Rainbow Weather. Our team collects data from a wide range of sources (radar, satellites, barometers, etc) and applies ML models to it, making an innovative product.
Our solution includes: web, android, ios client applications, a technologically diverse back-end, several different AI/ML services, monitoring and metrics collection.
You must have seen us as winners of the day and week at Product Hunt last August and the other day as nominees for the Golden Kitty Awards in the best mobile app category.

If you don't know about us, you can listen to the podcast with investor Yura Melnicek.

Over the last year of operation, we have done
  • By metrics we make the best precipitation forecast two hours ahead with updates every 10 minutes.
  • By metrics in North America and Britain we get ahead of Apple and worldwide we got ahead of AccuWeather and of The Weather Channel
  • We made an app that became successful on Product Hunt in the Golden Kitty Awards award in the best mobile app category.

What makes us different from other apps?
We have cool features that make us better than others. For example, push notification for sudden weather changes. If it rains in your location, we'll make sure to let you know to bring an umbrella.
