Block Builder / Ethereum Protocol Expert, TLV, 1D Remote

Location: Tel Aviv — hybrid (4 days in office / 1 day remote)

Why join us

We are building a next-generation block builder that augments Ethereums capabilities, unlocks new DeFi
primitives, and improves neutrality while making block participation more accessible. As a Protocol Expert youll
be the steward of protocol-level systems: youll author production-grade Rust services, define how blocks are
constructed and transactions are ordered, own PBS-related integrations, and partner with validators, relays and
searchers — directly shaping ordering and inclusion rules, hardening deterministic simulations and safety checks,
and driving measurable impact across the Ethereum ecosystem.

What youll build

A production-grade block builder platform and the off-chain infrastructure that powers it: block construction
algorithms, secure low-latency builderrelay communication and bundle handling, determin...
