FSL are the creators of the revolutionary move-and-earn game STEPN, a pioneering web3 social game GasHero an AI powered NFT marketplace MOOAR and Multichain DEX DOOAR.

Our products and community are unparalleled in the space and offer a chance to be part of something special. For example, being part of the STEPN community is so much more than owning a digital sneaker that pays you to move. It is a vibe. It’s a way to tell the world you’re in the know and care about your wellbeing. It’s a flex. It’s an experience that you can only understand once you join the club.

We started in Sep 2021, backed by Sequoia Capital, Folius Venture, Binance Lab and a mix of reputed Web2 and Web3 institutions. The public beta version of our first product went live on 20th Dec 2021 and we achieved one of the fastest growth speeds in the Web3 space, reaching the top 50 tokens by market cap. Our community growth is only matched by our insane shipping speed having launched three robust consumer-facing and infrastructure projects in less than a year.

At FSL, we have forged a name for ourselves by focusing on our community and product. Since our inception, we have experienced rapid growth, and we are now looking for a Senior Full Stack Engineer to join our team.
