You should understand what is asynchronous, how HTTP works, what is API and how to create and use it. You should know how to use and develop a database, either relational or document: MongoDB, MySQL, PostgreeSQL or other.
It would be cool if you know software architecture principles and have experience of designing and developing software from the scratch.
We love React and Redux, so most projects uses this technologies. We use Typescript, so you should know it or would like to learn it.
You should be able to do a markup with modern HTML and CSS. Most of our projects are made for modern browsers so you don't need to know how to make equal height columns with floats (but it is cool if you do :) ).
It is ok if you doesn't know something, we will teach you.
