Founding Engineer, Monaco Research

Monaco is a crypto-native research and development group building high-performance infrastructure for open financial systems. We’re a small, senior team operating at the intersection of TradFi speed and DeFi composability. If you thrive in fast-moving environments, write production-grade code, and have opinions about blockspace and trading mechanic, we’d love to meet you.

What You’ll Do

• Own and contribute to the core engineering behind Monaco’s CLOB (Central Limit Order Book), supporting both spot and perpetuals
• Build and optimize low-latency trading infrastructure
• Lead the smart contract development for Monaco’s Perpetuals product (Solidity)
• Improve performance of order matching systems with a strong focus on latency and reliability
• Ship production code for Monaco v1 and lead explorations into v2 architecture

You Might Be a Fit If You

• Have 3+ years of engineering experience, ideally across both TradFi and DeFi stacks
• Bring experience in Rust and Solidity, with the ability to navigate low-level systems and smart contracts
• Have worked at or adjacent to HFT firms (e.g., Citadel, Cubist, AQR) or were part of early engineering teams at onchain perps/CLOB protocols (like dYdX, Hyperliquid, Vertex)
• Have built or traded DeFi strategies and understand the nuances of real users, slippage, and gas fees
• Are based in NYC or willing to relocate
