About the role

About Fleek

Fleek (YC W22) is a B2B Marketplace for wholesale second hand fashion. We enable Gen-Z resellers and retail stores to buy from vintage clothing suppliers from around the world.

We are reimagining the supply chain of used clothing and empowering a whole new generation of sellers. At Fleek, we keep it circular, trendy, and sustainable.

Our Seed round was led by A16Z (Andressen-Horowitz) and we were part of YC’W22. We have COO of Shopify, Harley F. and the CEO of Ancestory.com, Deb Liu (She built out Facebook Marketplace) as angels.


Fleek is a set of funky individuals who find unity in diversity with the single mission of helping sustainability, promoting circular fashion while building a beautiful product experience.

Our 10 people team consists of ex-YC founders leading our engineering effort, ex-Uber & Doordash folks leading our operations and supply strategy. Alongside our Growth team is lead by folks who went to Cambridge, Oxford and UC Berkeley.

Technology stack

Fleek is built with a modern native stack with Javascript as its backbone and React, React Native as the frameworks for app development. We have two buyer and supplier facing apps on App Store and Play Store. We also have a website that currently runs on Shopify (to be soon deprecated).

We employ AWS as our cloud provider and use technologies in OpenSearch, DataFlow and Lambda, Video streaming to build on top.

Our philosophy is to reuse where possible and innovate when we can add value.

Role specific details

Now that Fleek has a consistent user base of ~ 1000 MAU (each spending upwards of $1000/mo); there’s a need to evolve from an MVP to a product that can support scale & personalization.

We are looking for a Full-Stack Ninja who has 4+ years of experience building and/or leading small tech teams in a Javascript native environment. In your role you will be:

  • Responsible for developing and hands-on coding in our backend (AWS) and frontend (React Native) environment
  • Evolve our rudimentary MVP into a sophisticated personalized marketplace software which is underpinned by using open technologies and efficient application of rules on top
  • Implement a native P2P video experience for the video shopping experience
  • Ability to communicate, guide and lead small software teams in terms of best practices in technology

Preferred Skills

  • 4+ years of experience with React.JS/ReactNative/Cotlin/Switft building out cross platform apps for iOS and Android
  • Experience working in backend/cloud environments like AWS or GCP
  • Experience working in a collaborative environment
  • Having worked at a startup is a must!
