Senior Backend Engineer

Kiosk
New York, NY

Kiosk is a new Farcaster client where social meets onchain. We want creators to be able to build a community from 0-to-1 all within the app. When onchain social meets onchain commerce, it should be easy to share a media-rich idea with your social graph, make it mintable as an NFT, gather like-minded collectors and collaborators in a channel, establish custom channel economics like tipping and distribution, and chat with your community – all without leaving the app.

We are a small, passionate team based in New York City, with a breadth of experience that has been building in this space for years. We’ve raised $21M in funding led by a16z crypto, Union Square Ventures, Electric Capital and Variant Fund.
