Right now, we’ve launched an alpha to a small number of users and have learned a lot from that launch. To deliver our intended developer experience, we’ll need to iterate with our users to get the UX right. We’re looking for an engineer who can focus on the frontend, excited about designing and refining the user interface on a weekly basis to get our product ready for a larger number of users.
