Staff Protocol Engineer
"What You'll Be Doing"
What You'll Be Doing
Designing and shipping the smart contracts behind trade execution, focused on security, simplicity, and gas efficiency
Building cross-chain execution, including solver and intent-based routing, so users get the best fill regardless of which chain a token lives on
Owning trigger execution for limit orders, stop losses, and other automated trades, ensuring they fire correctly and on time under heavy market load
Designing the read side of the system: indexing and serving onchain data accurately and with low latency for portfolios, PnL, and the social feed
Debugging hard production issues at the EVM level, from reverted transactions to gas spikes and chain reorgs
Setting the bar for protocol security across the team through design reviews, testing, and collaboration with external auditors
What We're Looking For
Staff+ level engineer (6+ years of experience) who can come up with and execute on plans autonomously
Deep understanding of the EVM, with production experience writing and shipping smart contracts in Solidity
Experience building offchain systems that interact with contracts at scale (execution bots, relayers, solvers, keepers, or indexers)
Strong grasp of DeFi primitives: AMMs, aggregators, MEV, and how transactions actually land onchain
Bonus Points
Experience with cross-chain infrastructure such as bridges, intents, or solver networks
Experience with Solana or other non-EVM chains
Familiarity with security tooling like Foundry, Slither, Echidna, or formal verification, and experience working through external audits
Rust or Go experience, or familiarity with client internals (geth, reth)
Active onchain traders — fomo's engineers use the app themselves to understand what to improve
