Title: Switchboard Senior Engineer

Location: Remote

Job Description:

What are we all about?

We are a team of builders and researchers on a mission to empower enterprises and developers worldwide to access and build on decentralized systems.

Our expertise covers several domains: Ethereum and Starknet protocol engineering, layer-2, cryptography research, protocol research, decentralized finance (DeFi), security auditing, formal verification, real-time monitoring, smart contract development, and dapps and enterprise engineering.

Working to solve some of the most challenging problems in the blockchain space, we frequently collaborate with, such as Ethereum Foundation, Starknet Foundation, Gnosis Chain, Flashbots, Forta Protocol, Lido, EigenLayer, Open Zeppelin, RISCZero, Aleph Zero, and many more.

Today, there are nearly 200 of us working remotely from over 45+ countries.

Are you the one?

Nethermind, a leading blockchain development company, has been actively researching and developing solutions in the MEV (Maximal Extractable Value) space, focusing on both Layer 1 and Layer 2 of the Ethereum ecosystem. Our team has been dedicating time and resources to understanding and implementing techniques that optimize MEV extraction while maintaining the integrity and security of the Ethereum blockchain. As we continue to explore the MEV domain, we are now expanding our research and development efforts to the emerging areas of preconfirmations and block building. We are looking for a talented and experienced Senior Engineer to join our team and contribute to the ongoing research and development in these areas, helping to shape the future of Ethereum infrastructure. If you are interested in MEV, preconfirmations, and block building, and would like to work alongside a dedicated team of researchers and engineers, Nethermind could be the perfect fit for you.
