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 the Role This post is part of our ongoing effort to connect with exceptional talent for future Product and Dev roles at Starknet Foundation. Great teams aren’t built overnight. That’s why we focus on meeting exceptional people early, so we’re ready when the right opportunity arises. The Product team at Starknet Foundation is a small group of generalist engineers with three main focuses: - Building tools and infrastructure for the Starknet ecosystem: data explorers, ETL pipelines, prediction markets, and developer-facing products. - Running developer programs: onboarding, training, and supporting builders across the Starknet network. - Working with Developer Partners (DPs): advising teams on technical decisions, resourcing, and hitting the milestones they need to unlock funding and optimize for success. We are always interested in connecting with great technical talent. While we may not have a specific position open at the moment, we encourage you to submit an 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.
