Core Protocol Engineer

Ritual is building a sovereign, execution layer for AI, with our private testnet already live and running. The Ritual chain is the first blockchain custom-built to support AI-native operations, designed from the ground up to enable a new class of applications at the intersection of crypto and AI. Our first product, ...

Design and implement extensions to EVM clients (Geth/Reth) for supporting stateful precompiles

We're seeking a Core Protocol Engineer with deep expertise with Ethereum execution clients to help us extend the EVM for next-generation compute capabilities. You'll work on expanding the execution layer to support novel precompiles, implement parallel execution patterns, and design systems for heterogeneous compute orchestration.
Implement novel mechanism design primitives, collaborating with our research team, into the execution layer
Develop and optimize transaction processing pipelines for heterogeneous workloads
Research and implement solutions for state access conflicts
Contribute to core protocol development and EIP implementations
Collaborate with the research team on protocol specifications and mechanism design improvements
Design and implement robust testing frameworks for execution client modifications

Deep understanding of EVM internals and Ethereum execution clients (Geth/Reth)
Strong experience implementing and optimizing precompiles
Expertise in Go and/or Rust for systems programming, and Solidity
Thorough knowledge of Ethereum's roadmap and active participation in protocol discussions
Experience with parallel execution patterns in blockchain systems
Strong understanding of consensus mechanisms and blockchain architecture
Ability to read, understand, and implement EIPs and protocol specifications
Proven track record of shipping production-grade blockchain systems
Ability to act quickly under high pressure scenarios and context switch at a high frequency
A high level of end-to-end ownership and self-direction, with excellent communication skills
Hungry, high-energy and ability to work within and meet deadlines in a fast-paced environment
Knowledge of mempool dynamics, transaction ordering and the mev-boost implementation
Background in mechanism design or market systems
Deep knowledge of proof systems and their trade-offs around prover time, verifier time, and proof size
Experience optimizing proof generation and verification pipelines
Experience with cross-chain bridges or interoperability protocols
Contributions to Ethereum client codebases
Background in distributed systems and concurrent programming
