About

My client, a fast-growing crypto market making start-up, is seeking a DeFi-focused Quant Engineer to help expand and refine their trading and liquidity infrastructure. This is a hands-on role working directly with the founders on the core technology that powers their onchain execution and research stack. Overview The successful candidate will bring strong engineering discipline combined with deep curiosity about how modern onchain markets operate. You will help design and optimise the systems responsible for connecting to AMMs, orderbook venues, and CEXs, while solving complex challenges around latency, finality, and liquidity dynamics across multiple chains. This role is ideal for someone who enjoys dissecting market microstructure, working with high-performance code, and building the technical foundations for next-generation DeFi strategies. Key Responsibilities Build and maintain low-latency connectivity between onchain AMMs, emerging onchain orderbooks, and major CEX venues. Develop high-performance components for pricing, execution, routing, and liquidity management across L1s and various L2 rollups. Optimise ingestion of real-time blockchain data, including mempool flows, state updates, and high-frequency market feeds. Work on the architecture behind cross-chain/rollup execution, accounting for different confirmation and settlement models. Design and prototype mechanisms for advanced liquidity strategies, including dynamic range adjustments, JIT-style liquidity, and MEV-aware execution logic. Contribute to internal research and tooling enabling faster iteration, clean data modelling, and robust risk controls. Required Skills & Experience Advanced degree in a quantitative or technical discipline (maths, physics, CS, engineering, statistics).</
