Senior React Front End Engineer

We are an early-stage start-up looking for a frontend engineer to add several new screens to our existing React.js administrative dashboard. We will have sizable such updates every 3-4 months and looking for someone whom we can collaborate with over extended periods of time. The ideal candidate will have delivered front-end dashboards using react.js successfully, communicates clearly, and works collaboratively. The ability to wireframe and execute the UI would be a big plus.
