What you'll do: - Build test platforms, automation frameworks, validation services, and AI-powered tools to improve testing efficiency and release quality. - Develop AI skills/agents for QA/RD scenarios such as requirement analysis, test case generation, test data generation, log analysis, defect triage, root cause analysis, regression selection, and test reporting. - Build self-service capabilities that help QA/RD teams execute validation, monitor test results, assess release readiness, and reduce manual testing effort. - Integrate automation and AI outputs with test management systems, dashboards, ticketing systems, and release processes. - Partner with QA and RD teams to identify testing pain points and convert them into reusable automation platforms or AI-based solutions. - Work closely with global QA, RD, product, and business teams across multiple countries/regions to support international e-commerce scenarios, localization needs, and cross-market release quality.

Minimum Qualifications: - Bachelor degree or above in Computer Science, Software Engineering, or a related technical field. - 3+ years of hands-on software development experience, preferably in test platform, automation, AI tooling, developer productivity, or quality engineering related areas. - Experience building test automation frameworks, validation tools, internal productivity tools, or CI/CD-related engineering solutions. - Strong understanding of software testing concepts, including requirement analysis, test design, regression testing, defect analysis, and release validation. - Strong engineering sense in building reliable, maintainable, and scalable solutions rather than one-off scripts. - Ability to work closely with QA and RD teams, understand real testing pain points, and turn them into practical engineering solutions. - Able to collaborate with cross-functional teams in an international environment.

Preferred Qualifications: - Experience building reusable testing infrastructure, automation platforms, AI tools, or internal productivity tools used by multiple teams. - Experience applying AI/LLM capabilities to improve testing efficiency, such as test case generation, test data generation, log analysis, defect triage, root cause analysis, regression selection, risk assessment, or test reporting. - Experience working on complex systems where quality depends on cross-service validation, data consistency, configuration correctness, or end-to-end business flows. - Experience integrating automation or AI outputs with test management systems, dashboards, ticketing systems, or release processes.
