Report to**

You’re exceptional with building application front-ends with a keen eye for UI and UX. You're not a UI/UX designer, but you know a bad experience when you see one with ideas on how to correct them. You’re a specialist. You can work with any frontend language, not just React vs Angular. You have a public profile of personal projects you’ve worked on, simply because you love it. You’ll make magic happen with our Events app’s attendee facing UIs, for responsive desktop/mobile and our forthcoming mobile app.

**What the job will bring you **
Set a standard for our front-end. We’ll be building new UIs for our products, focusing on our Events UIs, across multiple front-end languages, working with our now-hiring-for UI/UX designer. You’ll have ownership over the front-end architecture, under the approval of our CTO.
