Senior Reth Developer

Location: Remote (Full-Time)

Team: Taiko Alethia Engineering

Reports to: Engineering Director Gustavo Gonzalez

About Taiko

Taiko is Ethereum's first Based Rollup project. We're scaling Ethereum through a based rollup architecture and pioneering innovations like Layer 2 preconfirmations. Our mission is to deliver Ethereum's security and decentralization in a scalable, developer-friendly rollup — without compromise.

Role Overview

We are hiring a Senior Reth Developer to lead the integration and advancement of the Reth (Rust-based Ethereum) client for Taiko. You will adapt Reth into the canonical execution engine for Taiko’s Layer 2 node and optimize it for high-performance, rollup-specific use cases.

Responsibilities

• Extend and maintain Taiko’s Reth fork taiko-reth to meet execution layer needs.
• Profile and optimize taiko-reth for rollup workloads: fast sync, high-throughput ingestion, archive access, and block production.
• Refactor and modularize Reth crates for reuse across Taiko node components.
• Ensure full compliance with Ethereum standards including Engine API, JSON-RPC, and upcoming EIPs.
• Develop robust testing, simulation, and fuzzing infrastructure for critical execution paths.
• Collaborate with Taiko protocol, infra, and ZK teams to ensure seamless integration across the stack.
• Contribute to code reviews, performance audits, and open-source engagement.

Requirements

• 5+ years of experience in systems programming, with strong command of Rust.
• Deep understanding of Ethereum execution layer internals: block processing, mempool, and state transitions.
• Prior experience working on or contributing to Reth or other high-performance Ethereum clients.
• Skilled in profiling, performance tuning (perf, flamegraph), and memory-efficient Rust design.
• Capable of writing clean, testable, async-first Rust code.
• Comfortable with open-source workflows and GitHub collaboration.
• Able to work independently in a fast-paced, remote-first environment.
• Bonus: experience with rollup architectures, ZK systems, blob handling (EIP-4844), or MEV infra.

What We Offer

• Work on one of Ethereum’s most technically ambitious L2s — making it more secure, permissionless, and decentralized.
• Join a high-caliber, globally distributed team focused on open-source and Ethereum-aligned principles.
• Enjoy a fully remote and async-first work culture.
• Competitive compensation with strong token upside potential.
