Job description

Overview

We are seeking a highly analytical and proactive Risk Control Specialist to join our growing risk management team. In this role, you will be responsible for identifying fraud and risk patterns across card-based payment flows, designing and optimizing risk control strategies, and investigating suspicious activities to protect the business and its customers. You will work closely with product, engineering, compliance, banking partners, and card networks to ensure a secure and compliant payment ecosystem.

The ideal candidate has experience in payment risk, fraud prevention, or financial crime operations within crypto exchanges, Web3 payment platforms, cross-border payments, or payment anti-fraud environments. Strong data analysis skills, a deep understanding of card payment risks, and fluency in both Mandarin and English are essential for success in this role.

Responsibilities

• Risk analysis and pattern identification: Use transaction and user behaviour data to identify risk patterns in card-based deposit/withdrawal flows, including fraud, cash-out abuse, stolen card/card-not-present (CNP) fraud, and malicious chargebacks. Produce risk analysis reports.
• Strategy development and optimisation: Independently design, deploy, and tune risk control strategies (blacklists/whitelists, rule engines, risk scoring, etc.), covering application-level anti-fraud, transaction-level anti-fraud, and account risk monitoring.
• Case investigation and remediation: Conduct in-depth analysis of suspicious transactions and organised fraud rings, and translate findings into playbooks that feed back into strategy improvements.
• Metrics monitoring and review: Continuously monitor core metrics such as strategy hit rate, false-positive rate, and fraud loss rate, with regular reviews and iteration.
• Cross-functional collaboration: Work closely with product, engineering, compliance, customer support, banks, and card networks to drive risk issues through to resolution.

Requirements

• Experience

  • Familiar with risk points across the card deposit/withdrawal chain (3DS, chargebacks, cash-out abuse, stolen/CNP fraud, etc.).
  • Familiar with risk control logic for prepaid/virtual card issuance (application anti-fraud, transaction monitoring, money laundering detection, etc.).
  • Able to independently design and implement risk strategies, with a quantitative mindset around measuring strategy effectiveness.
  • Data-sensitive with clear logical thinking; able to spot risk patterns within large datasets.
  • Highly self-driven; able to independently push issues to resolution rather than relying on being assigned tasks.
  • Resilient under pressure; able to respond to sudden risk events.
  • Proficiency in SQL with the ability to independently extract and analyse data is required;
  • Experience with Python and/or BI tools (Tableau, Metabase, etc.) is a plus.
