Hardware Engineer (m/f/d) at Breeze Technologies


Every day we inhale and exhale around 20.000 times, while our air becomes more and more polluted. Air pollution kills more than 7 million people per year. Yet, we are missing crucial data to develop strategies how to curb emissions. We at Breeze Technologies fight every day to create more sustainable cities for a cleaner tomorrow.

Breeze Technologies is a leading startup in the field of air quality sensors, air quality data and clean air action analytics. We support cities, businesses and NGOs to monitor hyperlocal air quality and design more efficient clean air action plans with Artificial Intelligence and the Internet of Things.

Our startup develops its own hardware – our air quality sensors – and software – our Environmental Intelligence Cloud – at our headquarters in Hamburg, Germany. Both enable our customers to generate local air quality insights and create a healthier environment.

Breeze was founded in 2015 and has since scaled to a customer base in 9 countries as well as international partnerships, for instance with Microsoft and the US Homeland Security. Our work has received numerous international awards, including the “Hamburger Gründerpreis” (Hamburg Founders Award) and a commendation by the German Federal President.
