We are developing a new block builder to democratize and counter centralization in the Ethereum ecosystem. Our block builder augments the capabilities of the Ethereum network and enables new
Defi primitives.
About the Role:
We're seeking an experienced Ethereum backend Developer proficient in deep blockchain protocols and Rust to join our team.
In this role, you will:
Design high-performance systems optimized for low latency and scalability, with direct impact on the mainnet, contributing to a fairer and more efficient Ethereum network.
Design and develop scalable backend services in Rust, focusing on ultra?low latency and high throughput for Ethereum payload submission and block construction.
Architect and implement builder-relay payload protocols (e.g. MEV?Boost), enabling in?slot timing optimization, censorship?resistance, and ultra?parallelized block generation.
Requirements: Qualifications:
Strong understanding of Ethereum protocols, including PBS/MEV?Boost flows, fork?choice logic, slot/epoch timing, and relay security.
Expertise in Rust (async, zero?cost abstractions, performance tuning); familiarity with Go or C ++ is a plus.
Proficiency in Python for simulation, data analysis, and tooling.
10+ years of experience, at least 2 years in building on top of off-chain protocols.
Experience with revM, reth/geth internals, or similar blockchain development tools.
Preferred Qualifications:
Prior contributions to core Ethereum clients, EIPs, or open?source MEV tooling.
Hands?on with Kubernetes, Docker, and bare?metal performance tuning.
