1. Spot Market-Making Execution (Responsible for Depth Performance)

Responsible for order placement execution, depth replenishment, spread maintenance, and order book structure management for spot trading pairs. Accountable for depth quality, spread stability, and overall order book performance. Quickly address depth gaps, price level discontinuities, and order book imbalances to maintain robust trading depth and liquidity.

2. Hedging Execution (Risk Exposure Control)

Based on inventory and market fluctuations, execute fundamental hedging operations to maintain risk neutrality. Monitor price relationships between internal and external markets, promptly adjust hedging positions, and ensure overall positions and risk exposures remain within controllable limits.

3. Data Output and Periodic Review

Produce weekly reports on key market-making and hedging metrics along with structured review analyses. Analyze depth changes, order book structure, and hedging performance, and propose actionable optimization recommendations.

4. Depth Diagnostics and Internal Optimization Recommendations

Continuously monitor core liquidity indicators such as depth structure, order book continuity, and spread rationality. Identify root causes of depth deterioration and structural anomalies, and propose actionable internal optimization plans. Collaborate with risk control, operations, and strategy teams to implement improvements, without any external communications.

5. Order Book Risk Identification

Identify abnormal trading behaviors such as unusual taker orders, abnormal cancellations, and potential manipulation signals. Take timely countermeasures when structural risks appear in the order book and coordinate responses with internal teams.

Requirements

Must have:

• Minimum 3 years of hands-on spot market-making experience (required), covering order placement execution, depth replenishment, spread management, and order book maintenance.

• Ability to independently read the order book, assess depth risks, structural issues, and price imbalances. Experience in inventory management and fundamental hedging. Capable of rapidly addressing order book issues in a fast-paced environment.

• Basic data analysis skills.

• Basic risk control identification skills, including:

- Abnormal trade structures (persistent aggressive taker orders in one direction)

- Abnormal cancellations (instant cancellations, false depth)

- Suspicious trading behaviors (wash trading, spoofing, order inducement)

- High-frequency strategy interference (abnormal impact costs, frequent order book penetration)

- Potential manipulation signals (pump-and-dump, price suppression for accumulation)

• Familiarity with external market linkages (Binance/OKX) and common arbitrage strategies (cross-exchange arbitrage, spread arbitrage).

• Experience using market-making bots or automated order execution systems.
