Medior Data / Analytics Engineer

  • Amsterdam, Noord-Holland, Netherlands

Job description

Coolgradient is a fast-growing green-tech start-up with a clear vision to make our digital footprint more sustainable.


Every swipe, every like, every TikTok video we upload, every Zoom call we have, every Netflix video we watch, or everything we buy online is all processed and depends on… data centers. However, these data centers consume large amounts of energy due to the underlying technology we use every day all day.


We have developed an AI-based analytics platform that captures the entire data center (DC) infrastructure—"from roof to room"—to bring the whole DC into a more optimal state. This platform saves energy, water, and scope 3 emissions while increasing reliability and sustainability in data centers across countries like Germany, France, the UK, Australia, and The Netherlands.

We are looking for a Medior Data / Analytics Engineer that can help us develop and scale our modern data warehouse aka 'data / analytics factory'
