Senior Software Engineer, Backend, EigenDA

Eigen Labs is more than just a leading name in the blockchain space. We’re the driving force behind EigenLayer, a game-changing solution that revolutionizes crypto-economic security. Imagine a world where blockchain projects break free from the shackles of the scaling trilemma and capital limitations.

We’re building a platform to deliver security to novel distributed applications. In today's blockchain ecosystem, each service is typically secured by its own tokenized trust-network. With EigenLayer, services can build upon the established security of the Ethereum trust network, unlocking untold scalability while maintaining security and decentralization.

Enter EigenDA: Provisioning data availability is one of the key components for scaling blockchains, and specifically Layer2 rollups. EigenDA is a secure, high throughput, and decentralized data availability (DA) service built on top of Ethereum using the EigenLayer restaking primitive. Developed by Eigen Labs, EigenDA is the first Autonomous Verifiable Service (AVS) to launch on EigenLayer. Restakers will be able to delegate stake to node operators performing validation tasks for EigenDA in exchange for service payments, and rollups will be able to post data to EigenDA in order to access lower transaction costs, higher transaction throughput, and secure composability across the EigenLayer ecosystem.

With EigenLayer, building blockchain infrastructure modules (AVSs) in a permissionless manner is no longer a hypothetical—it's our reality. Now, we invite you to be part of this exciting journey.

This is a full-time position that is fully remote or located with the largely Seattle-based team.

This role represents an opportunity to develop deep expertise in rollup architecture and implementation while making upstream contributions to various rollup frameworks, where generic DA has yet to be developed. You will have a significant impact on DA's ability to provide value to Rollups, the EigenLayer product, the DeFi industry, and the world. All while working alongside the biggest projects and brightest minds in DeFi and Ethereum. If you’re looking to collaborate with a talented team of engineers, driving innovation and inventing groundbreaking technologies, we look forward to hearing from you!
