About the job

Hang is building the future of loyalty for brands
At Hang, we believe that the future of brand loyalty will be powered by NFTs. We are building a no-code, enterprise solution that helps brands increase customer LTV by harnessing the power of web3 to better incentivize users and supercharge customer loyalty. Our software helps brands verify users wherever they may be, enabling users to earn and be rewarded for taking actions that brands desire.
Our customers include top brands across food and bev, e-commerce and retail, hospitality, and entertainment. We recently raised our Series A from top-tier investors, founders, and brand CEOs and are quickly expanding the team.

About The Role

As part of the backend team, you will work on greenfield projects, add to existing APIs, and build microservervices/APIs from scratch that will power Hang’s B2B reward system for businesses and users. We currently work with Ruby and Node.js across our backend services, and we use React on the frontend.
