Haskell developer

We are looking for a hardcore Haskell developer for innovative web application projects.

Our team builds advanced cloud software with innovative web technologies, including (but not limited to):

–    TypeScript
–    Reactjs
–    .Net Core

We integrate functional programming in our daily lives, and strive towards including all possible advanced concepts that we can find to make our code elegant, maintainable, and performant. We even build and use our own languages and monads.

If you find functors trivial, you believe that monad transformers are kind of obvious, and find that free monads are the place to be, then give us a call.

We strive towards working at the highest possible level of engineering, and try to include advanced software engineering concepts in our daily work. Which has lead to elegant solutions for complex web applications like and GrandeOmega.
