Ervaren frontend developer

For the development of several dynamic graphs we are looking for a hands-on frontend developer. Our client is a well funded FinTech startup in the Netherlands for whom we have to develop software on a remote basis. We already have a tech lead, but we need to ramp up the team with a couple of extra frontend developers (1 or 2 FTE). Candidates must have extensive background and experience in Javascript, HTML, CSS etc. We are working with Polymer Project and Raphaël Javascript Library, so experience in this field is very welcome!
