Quant Trading Developer (DEX/CEX)

Location: Shenzhen Key responsibilities Latency: Lead the work to improve our execution speed by cutting latency, jitter and bottlenecks across the tick-to-trade path (node sync, market data, network, order signing and submission), without compromising stability. Trading: Build and trade automated Hyperliquid strategies (arbitrage, liquidations, funding capture) with firm capital, and own the P&L. Live risk: Manage positions, leverage, margin and funding in real time within risk limits. Node infrastructure: Build and run self-hosted Hyperliquid (or other DEX) nodes and execution infrastructure, keeping them stable and highly available. On-chain execution code: Build market-data handlers, internal order books and order routing for Hyperliquid and other on-chain venues. Monitoring and controls: Track latency (order round-trip, market-data delay, fill quality) and build kill switches and position limits. Requirements Latency: Proven, measurable latency reduction in production while keeping live systems stable. Hands-on with latency profiling, network tuning, CPU pinning and async event loops. Trading track record: 3+ years of live quant or systematic prop trading with direct P&L responsibility, running perpetual futures strategies and managing leverage and funding in real time. On-chain node experience: Has built and run a Hyperliquid or other DEX node, and can explain its architecture, bottlenecks and latency trade-offs in depth. On-chain coding: Strong with RPC, WebSocket feeds, transaction signing and smart contracts. Python required; Rust, C++ or Go a strong plus. Deep understanding of perpetuals, funding, leverage, liquidations and on-chain order books. Solid grasp of exchange microstructure (order types, order-book events, rate limits). Bachelor’s or above in Computer Science, Engineering, Finance, Mathematics or a related quantitative field. Strongly preferred Trading across DEX and CEX venues, including cross-venue arbitrage. Low-latency or HFT background (e.g. lock-free structures, ring buffers).
