About the role

Key responsibilities & impact

Help evolve our block-building and MEV-related systems,
Work across the Ethereum ecosystem, including Layer 2s

Requirements

What you’ll need

Write high-performance Rust and enjoy squeezing latency out of critical paths (profiling, flamegraphs, allocator choices, async/runtime tuning, lock contention, cache locality, zero-copy where it matters).
Have deep EVM knowledge, including transaction execution mechanics (gas accounting, calldata/memory/storage semantics), state access patterns, and the practical implications of opcodes and precompiles for real-world workloads.
Understand the MEV ecosystem end-to-end, from proposer/builder separation and relays to private orderflow, builder strategies, and the incentives that shape behaviour in production networks.
Have done MEV searching yourself (or built MEV-adjacent systems).
Are familiar with the transaction supply chain, including mempool dynamics, propagation/latency effects, private RPCs, orderflow providers, builders/relays.
Are passionate about Ethereum, proof-of-stake blockchains, and/or decentralised systems
