In addition to the UI skills Ed has defined, we also make heavy use of CSS and bootstrap. Any experience with legacy technologies like flex is also very useful.
Regarding the backend, I would add spring, and hibernate as critical skills.
Experience with Jenkins and Maven are also very valuable.
Also, we are an Agile/Scrum shop. We like to see experience with Scrum.
We like to see candidates who have demonstrated a commitment to quality though practicing, code reviews, unit testing, functional testing.
Other skills like TDD are also very helpful.
We have very collaborative teams so demonstrated experience
