Full Stack Engineering Lead

Are you passionate about shaping the future of DeFi? Join our innovative startup, firefly, as Engineering Lead and be part of our mission to take decentralized finance to the next level with our premier Modular DEX.

Our aim is to “_Empower the Investor_” with compelling technology to realize their potential, whether as a trader or liquidity provider.

We are a group of product managers and developers from companies such as Amazon.com and Twitter. Having launched firefly in April, we’ve become the leading native DEX on Manta Pacific, a top Modular L2 with $800M TVL on-chain.

firefly is a DEX with ‘CEX-like features’ such as limit orders to buy at pre-defined prices and take-profit sell orders to exit a position when a certain profit’s been reached.

firefly was one of the few projects (out of 175 on chain) to be admitted to Manta’s coveted Zk Accelerator for promising, high-potential decentralized applications.
