Backend Engineer

CleanHub harnesses the power of tech to address one of the world’s most pressing issues: ocean plastic.

Our lightweight platform enables effective waste management systems to be set up quickly in the coastal areas where they’re needed most. Through our app we track and trace the entire logistics chain to provide the digital evidence for every kg of plastic that did not end up in our oceans. Check out our live impact

You will be joining CleanHub at a critical and exciting time. In our first two years of operation we financed the collection of 1’000’000kg (equivalent to 100 million soda bottles) of ocean bound plastic – now it’s time to scale the impact.

We’re looking for an experienced backend engineer to help us shape the data structures and APIs which will enable the traceability of ocean-bound plastic.

In this role you will work closely with the CTO and the product management. Moreover, you will also interact with the operational team on the ground to always have the complete picture required to define the CleanHub APIs.
