Full Stack Engineer (Java, React)

We are Leaf.

Leaf is on a mission to upend the way companies buy and sell transportation. Every year, billions of dollars, hundreds of megatons of carbon and millions of person-hours are wasted because the companies who ship goods and the companies who carry them aren’t upfront about their needs and abilities. Our platform finds ways for buyers and sellers to contract binding commitments for plannable and predictable freight and allows those contracts to be traded when needs change. In time, Leaf will become the hub through which the trillion-dollar American freight market is managed.

We are a team of experienced, smart, and mildly disagreeable troublemakers who like taking on unreasonably big challenges; we know how to build things, we’ve lived what’s broken in this industry, and we’re looking for bright, ambitious people to help us drag the transportation world kicking and screaming into the 21st century.
