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. Saving energy and increasing reliability, resulting in a more sustainable data center in countries like Germany, France, Switzerland, UK, Ireland and The Netherlands. 

We are looking for a skilled Data Warehouse developer M/F/X with a knack for IoT, mechanics and sustainability or energy technology to join our team.

  • Improve pipelines, ELT ánd (dimensional) data models.
  • Babysit current ELT pipelines.
  • Integrate with existing ánd new MLOps.
  • Work with tech stack like Snowflake, dbt, Azure ML, and others (more coming and we’re definitely open for other suggestions).
  • But… you’re definitely able to mold and change this position according to your own qualities, expertise, and beliefs on how to accelerate our growth.

Job requirements

  • Knowledge of designing, creating, and managing (cloud) databases.
  • Experience in setting up, maintaining, and improving DevOps environments.
  • Excellent expertise in dimensional data (warehouse) modeling.
  • Know how to get the best out of Snowflake and leverage the pros of dbt.

  • Experience with (real-time) sensor data from an industrial environment will be a big plus


  • Working on making the world of data centers more sustainable
  • Enjoy a competitive salary, pension scheme, holiday allowance, and disability insurance.
  • Our goal is to increase our impact and grow. We want you to grow with us and offer an Employee Stock Option Plan.
  • A hybrid home-office-remote policy with flexible working hours where we value your regular presence to enjoy team dynamics, but we like to support the flexibility that fits your daily rhythm and preference.
  • Lots of mobility options, where we provide a lease car, public transportation subscription, or company bike, or we’ll reimburse your travels when you prefer to use your own means of mobility.
  • Lots of opportunities for professional growth and development.
