From the employer

• Own the testing lifecycle for new features and changes, including scoping, risk assessment, test depth, and release readiness.
• Build and maintain automated tests covering API, UI, integration, and regression, and reduce flaky tests.
• Design and run load, stress, and performance tests on high-risk areas (order flow, matching and settlement, balances, deposits/withdrawals), analyze results, and report bottlenecks to engineering.
• Use AI tools to speed up test generation, analysis, and triage, and share what works with the team.
• Integrate automated tests into CI/CD pipelines with reliable quality gates.
• Lead testing on complex or high-severity changes and make release sign-off recommendations.
• Own the test automation architecture (frameworks, test data, environments) in line with QA standards set by the Director.
• Mentor QA engineers through code reviews and pairing.
• Report quality metrics (defect escape rate, critical-path coverage, release stability) to the Director and stakeholders, and raise quality and release risks early, backed by data.

• 7+ years in software QA/test engineering with a strong automation focus.
• Must be fluent in Mandarin.
• Hands-on automation experience in Python, JavaScript/TypeScript, or Java, including designing or substantially owning a framework.
• Hands-on performance/load testing experience (e.g., k6, JMeter, Locust, Gatling).
• Experience testing APIs and backend/distributed systems.
• Experience with CI/CD (e.g., GitLab CI, Jenkins, GitHub Actions) in an agile environment.
• Ability to learn complex transactional or financial logic quickly, and clear communication with engineers and product.
• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
• Nice to have: Experience in crypto, trading, exchange, payments, or other financial systems. Experience testing wallet/custody or blockchain integrations. Practical experience using AI/LLM tools in testing.
