Zhijing Singapore Pte Ltd Hiring! Full Time Low-Latency Arbitrage Developer in Hong Kong, Earn up to HKD 90,000 - Ricebowl

About the role

Build and speed up our blockchain cross-exchange arbitrage systems across CEXs and DEXs (Bybit, Hyperliquid etc). The goal is to be faster than competing arbitrageurs while keeping production stable.

Responsibilities

• Design the multi-venue HFT arbitrage platform: market data, order-book normalisation, opportunity detection, multi-leg execution and hedging.
• Cut tick-to-trade latency to each venue through co-location, cloud-region placement, network/route optimisation and WebSocket/API tuning.
• Speed up on-chain execution through self-hosted nodes, RPC and transaction propagation.
• Profile and remove latency, jitter and throughput bottlenecks (network, kernel, serialisation, event loops).
• Handle partial fills, leg risk, rate limits and venue outages.
• Build monitoring, kill switches and alerts.

Requirements

• Blockchain trading-side experience: 2+ years building trading systems for a crypto HFT or trading firm (market maker, prop shop, arbitrage desk). Exchange-side or TradFi-only backgrounds are not suitable.
• Network-level latency: hands-on co-location near exchange matching engines, network/route optimisation, NIC/socket tuning. Kernel bypass is a strong plus.
• Measurable results: a proven record of reducing latency in live production, with numbers (µs/ms).
• Multi-exchange: built systems connected to multiple CEXs/DEXs at the same time.
• C++ or Rust required. Python or Go is a plus.
• Low-latency skills: CPU pinning, lock-free structures, ring buffers, async event loops.
• Bachelor’s degree in CS, Engineering, Maths or a related field.

Strongly preferred

• Cross-exchange arbitrage experience (CEX-CEX / CEX-DEX).
• Self-hosted nodes (Hyperliquid, Solana, EVM) built to speed up execution.
• Knowledge of perpetuals, funding, fees and rebates.
