Very much desired skills

• Coding to AWS EC2 APIs (amazonica or similar Clojure wrapper, or java APIs)
  
• Linux (CentOS in particular) in AWS (cloud-init, similar processes)

Nice to have skills

• Selenium related tools such as Selenium Grid
• Traditional load testing tools (and knowledge of their limitations) such as LoadRunner

For those interested, our application is a single-page app using ClojureScript and Om on the client and Clojure on the server. It is a highly dynamic app, every single change to the database results in automatic updates being sent out to all clients watching the relevant resources. We use a combination of REST routes for change requests and browserchannel for async push of data updates to make this happen.

Unfortunately, these technologies have also made it quite challenging to load test. In particular, we’ve found that it is difficult to get most traditional load testing tools to work well with browserchannel. For this reason we’ve settle on Selenium to simulate load. We’re using AWS to host and build our testing environment.
