Water is arguably the most important resource in the world and yet the industry is notoriously slow at innovating and adopting new technologies that allow them to easily automate endless hours of non-productive admin work from skilled workers. The cost of water is rising as an aging workforce is unable to adapt and multi-million dollar infrastructure decisions are being made without the best data. Our mission is about making water better, and it starts with the professionals at the nexus of all water decisions in a community. Klir will be the operating system for water and we have started on that journey by building the first work enablement platform for water. It’s designed to reduce the burden of administration so the experts can dedicate their precious time to solving a critical problem for our species.

Founded originally in Dublin, Ireland in 2018, Klir is a US Headquartered company with offices in the US, Canada and Ireland. Klir is a remote first company and is one of the fastest growing, SaaS companies in the water industry. We are venture backed by some of the highest profile and most reputable funds including Insight Partners, Bowery Capital & Spider Capital.

 Location: This position is fully remote.
