Head of Ecosystem & Community (Rollup Infrastructure)

Location: Remote - US or Europe

Compensation: $150K - $220K

We are an ambitious, early-stage infrastructure company backed by leading figures in the Ethereum ecosystem. Our bold vision is to revolutionize rollup design by achieving synchronous cross-chain composability. We are building a modular rollup framework that allows individual chains to remain sovereign while enabling atomic, seamless interactions—eliminating the need for trusted bridges or brittle asynchronous calls.

We are pioneering a new architecture where app-specific layers can interoperate as smoothly as smart contracts on a single chain. We are seeking a crypto-native Head of Ecosystem & Community to drive adoption, build our developer community, and communicate our vision for a composable future.

You will be responsible for defining and executing the strategy to build and scale our developer ecosystem, drive the adoption of our modular rollup technology, and amplify our technical vision within the broader crypto community.
