Senior Full Stack Developer

About Hiotlabs

We are Hiotlabs, a startup+ with our roots in software and technology. We are a product company that leverage IoT and Machine Learning to create societal value through developing tech that prevents and minimise property damage and promotes sustainability. 

Our goal is not only to help reduce property damage by water, but also to help our customers reduce water usage in their homes – by tracking when they use water and how much.

We were recently acquired by Polygon Group, so now we are a startup+, with autonomy but access to the global reach and expertise of Polygon.

We think big dreams, get things done and have fun.
