Your challenges:

Our tool provides several different services, written in Haskell, Python, and Rust.

In this position, you will be responsible for the architecture, development, and maintenance of new and old image-related features in our application. An important aspect of our work is scaling our services to the next level, so we can handle another order of magnitude increase in throughput while keeping our app fast and responsive.
