About the Role

You will help evolve block-building and MEV-related systems and work across the Ethereum ecosystem, including Layer 2s. You will write high-performance Rust, profile and reduce latency in critical paths (profiling, flamegraphs, allocator choices, async/runtime tuning), and optimise lock contention, cache locality and zero-copy paths. You will work with transaction execution mechanics, mempool dynamics, propagation and private RPCs, and collaborate on builder/relay and orderflow related systems.

Requirements

• Experienced software engineer
• Rust programming experience
• Deep EVM knowledge including transaction execution mechanics
• Knowledge of gas accounting, calldata, memory and storage semantics
• Understanding of opcode and precompile implications
• Familiarity with MEV ecosystem and proposer/builder separation
• Experience with MEV searching or MEV-adjacent systems
• Familiarity with mempool dynamics, propagation, latency and private RPCs
• Knowledge of builders, relays and orderflow providers
• Passion for Ethereum and proof-of-stake blockchains

Responsibilities

• Evolve block-building and MEV-related systems
• Write high-performance Rust
• Profile and reduce latency in critical paths
• Tune allocators and async/runtime settings
• Reduce lock contention and improve cache locality
• Apply zero-copy techniques where appropriate
• Work across Ethereum ecosystem including Layer 2s
• Engage with mempool dynamics, propagation and private RPCs
• Support builder, relay and orderflow integration
