DeFi Quant Engineer

Albert Bow, a venture-backed digital asset trading technology firm, is looking for a DeFi Quant Engineer to support the development of advanced onchain and offchain trading infrastructure. You will work across centralised and decentralised trading venues with a strong focus on liquidity, execution and high-performance trading systems.

What you'll do

• Extend and improve onchain and offchain connectivity across AMMs and orderbook venues, including Uniswap-v3-style pools, Hyperliquid and major CEXs
• Work across different L2 finalisation models, including optimistic and ZK rollups, fraud-proof and validity-proof windows, and fast versus delayed settlement guarantees
• Fine-tune and benchmark core pricing and execution engines for strategies across tick-range LP management, DEX-CEX arbitrage, MEV-aware routing and cross-rollup execution
• Optimise data ingestion and network pathways for ultra-fast access to mempool flows, onchain state diffs and high-frequency market data across L1 and multiple L2 environments
• Design, develop and validate new components for intelligent liquidity strategies, including JIT liquidity, dynamic range management, trade monitoring and real-time risk controls
• Build systems that account for the latency, finality and settlement characteristics of different rollup ecosystems

What you bring

• An advanced degree in mathematics, statistics, physics, computer science or a similar technical subject
• 2+ years of strong applied programming experience in Rust and Solidity
• Excellent onchain markets intuition and the ability to understand why and how specific market opportunities exist
• Experience building low-latency, high-throughput systems for onchain data processing or trading
• Strong ability to write high-performance, multi-threaded and asynchronous code
• Experience developing scalable distributed systems and services interacting with L1 and L2 networks
• Solid understanding of database systems, basic SQL and efficient state and query modelling
• Comfort working with Linux/Unix, AWS, Git, Docker and modern DevOps workflows

Location: Candidates based in London, or open to self-relocating to London, are preferred due to the in-person nature of the team.
