Python Backend Engineer

We are looking for a smart, enthusiastic back end software engineer with a keen interest in current technology and engineering.

Using your experience of python, p2p/distributed platforms and software engineering best practices, you will be involved in the design and implementation of secure and scalable applications that are transforming the diamond industry.
