Senior Ethereum Protocol Engineer (Rust)

Remote · Full-time · Senior

What is your new project?

Domain: Blockchain, Ethereum Protocols

Location: Israel

Company size: 2-10 employees

Founded: 2024

What makes this project exciting?

Join a team that is shaping the future of Ethereum! This project builds a new block builder to strengthen decentralization and enable new DeFi primitives.

You’ll work on low-latency backend systems in Rust, block-relay protocols, and MEV-Boost flows - all with direct impact on the Ethereum mainnet. It’s a chance to collaborate with top blockchain engineers, contribute to open-source Ethereum tooling, and influence protocol-level decisions.

If you want your code to make a real difference in the Ethereum ecosystem, this is the place to do it.

What makes you a great fit

  • 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.

Your day-to-day in this position

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.
  • Optimize system performance through advanced Rust practices and low‑level orchestration.
  • Influence critical protocol decisions and drive measurable mainnet improvements through your expertise.

Why work with us?

Our Client Offers:

  • Flexible working hours.
  • 20 vacation days.
  • Standard sick leave.
  • Social benefits.
