About the Job

Requirements

At least 2 years of experience building trading systems for a crypto high-frequency trading or trading firm, such as a market maker, proprietary trading shop, or arbitrage desk; exchange-side or traditional-finance-only backgrounds are not suitable.
Hands-on experience with co-location near exchange matching engines, network and route optimization, and network interface card and socket tuning; kernel bypass is a strong plus.
A proven record of reducing latency in live production, with quantified results in microseconds or milliseconds.
Experience building systems connected to multiple centralized and decentralized exchanges simultaneously.
Proficiency in C++ or Rust is required.
Low-latency skills including CPU pinning, lock-free structures, ring buffers, and asynchronous event loops.
A bachelor's degree in Computer Science, Engineering, Mathematics, or a related field.

Responsibilities

Design the multi-venue high-frequency trading arbitrage platform, including market data, order-book normalization, opportunity detection, multi-leg execution, and hedging.
Reduce tick-to-trade latency to each venue through co-location, cloud-region placement, network and route optimization, and WebSocket/API tuning.
Speed up on-chain execution through self-hosted nodes, remote procedure calls, and transaction propagation.
Profile and remove latency, jitter, and throughput bottlenecks across networks, kernels, serialization, and event loops.
Handle partial fills, leg risk, rate limits, and venue outages.
Build monitoring, kill switches, and alerts.

Desired Qualifications

Python or Go proficiency.
Cross-exchange arbitrage experience, including centralized exchange-to-centralized exchange or centralized exchange-to-decentralized exchange arbitrage.
Experience building self-hosted nodes for Hyperliquid, Solana, or Ethereum Virtual Machine networks to speed up execution.
Knowledge of perpetuals, funding, fees, and rebates.

Location: Shenzhen Office

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.
