Junior Field Service Technician Job Description

Description of Moleaer Company:

Moleaer Company is a venture-backed technology company that is privately owned and is based in Hawthorne, California. It is the category creator and global leader in nanobubble technology, which is revolutionizing how industries use water. The only fundamental scientific innovation in water in the past 30 years, nanobubbles drive sustainability, enabling industries to produce more while using significantly less water, energy, and chemicals. Recognized as one of America's Top GreenTech Companies for 2024 by TIME magazine, Moleaer is an incredibly dynamic and fast-growing company with a tremendous opportunity for career growth.

Water is our most precious resource. Not only do we need it to live, but we also use it in virtually every industrial process from food production to mining to mixing concrete. Moleaer’s mission is to unlock the power of water to do more with less. Our patented nanobubble technology improves sustainable food production and processing, water and wastewater treatment, natural resource recovery, and we can even restore aquatic ecosystems sustainably – and we do all of this with nanobubbles, not chemicals.

Nanobubbles are 2,500 times smaller than a grain of salt and have properties that allow them to supersaturate water with oxygen, form natural oxidants for disinfection, and increase water’s ability to permeate soil, rock, and even clothes in a washing machine. Our technology has been validated by extensive research, and we currently have over 2,500 installations in more than 50 countries.
