Required Skills: Core Java, Postgress

Other Skills: AWS

Akka is not Mandatory

This is a back-end project. We are migrating existing application to the cloud. For that we are migrating old apps to new frameworks. Akka is the framework, Postgres is the database. There are multiple databases but that's the one we are using. We are working one application at a time. We are prototyping how to do it. Once we have that process, we'll be able to migrate multiple at the same time.

Normal core java.

A Java guy who wants big data won't find big data here. There is AWS here but there is a devops team here already.

AWS would be a 'nice to have'.

DevOps person already on the team. They need a core java person to round out the team.
