About the Starknet Foundation The Starknet Foundation is the steward of Starknet, a permissionless validity rollup designed to scale the world’s most important blockchains without compromise. Having pioneered ZK-STARK technology to scale Ethereum, we are now entering a new era as the first network to settle simultaneously on both Bitcoin and Ethereum. Joining the Starknet Foundation now places you at the epicenter of this pivotal phase and offers a rare, ground-floor opportunity to shape how BTCFi evolves. This is a unique chance to build the first unified execution layer that turns the world’s most secure assets into productive capital for a billion users and it requires exceptional talent. We’re looking for people who think in systems, operate well in ambiguity, and are motivated by long-term impact over short-term wins. If you care about building durable foundations (technical, organizational, or ecosystem-level) and want your work to meaningfully shape how decentralized systems scale, this is the place to do it. About this Posting: We are always interested in connecting with talented individuals who share our passion for freedom tech. While we may not have a specific position open at the moment, we encourage you to submit an open application and tell us a little about yourself and your interest in Starknet. We review these regularly and will get in touch if a fitting role opens or to meet-up at upcoming conferences. ======================= Starknet technology is developed by Starkware and is nurtured by the independent Starknet Foundation - two separate teams driving the network forward together.
