Software Engineer — TechChain Talent, EMEA

About the Company

Our client is building decentralised infrastructure for the Ethereum ecosystem. Their flagship liquid restaking protocol is designed to lower barriers for at-home stakers and counter centralisation risks from existing staking pools. They are also building an Ethereum based rollup that enables credibly neutral transaction sequencing and ensures value flows back to Ethereum’s L1 validators. They are backed by leading crypto VCs, major exchanges and global financial institutions, and are expanding the team with people ready to shape the future of Ethereum’s infrastructure.

About the Role

We’re looking for an ambitious Senior Blockchain Engineer and Researcher to play a key role in advancing the company’s Ethereum Layer 2 rollup.
