Senior Backend Software Engineer, Global E-commerce Governance Business

Responsibilities

Global E-commerce is a content E-commerce business with international short video product as the carrier. It is committed to becoming the first choice for users to discover and purchase good products with affordable prices. Global E-commerce business team hopes to provide users with more tailored and efficient consumption experience, enabling merchants to receive reliable platform services in different scenarios such as live e-commerce, short video content E-commerce, so as to make more affordable and high-quality products sell easily and a better life within reach.

Global E-commerce Governance keeps our marketplace safe and trustworthy for buyers, sellers, creators, and brands. The Product Governance & IPR team builds the systems that ensure every listing on the platform is authentic, compliant, and accurately presented — and that intellectual property is respected across the marketplace. Our work spans two connected areas: product governance (detecting counterfeit, prohibited, and low-quality listings;

enforcing product information quality; meeting regulatory requirements across global markets) and IP protection (proactive infringement detection, rights-holder tooling, and notice-and-takedown workflows aligned with legal frameworks such as the DMCA and EU DSA). Our systems screen hundreds of millions of listings using rule engines, ML models, and LLM-based review.

Responsibilities:

• Own solution design and system architecture for product governance and IPR services — listing risk screening, product quality enforcement, policy-driven review pipelines — and write high-quality code for critical paths.
• Design and evolve IP protection systems end-to-end: rights-holder reporting and brand-protection platforms, notice-and-takedown workflows with SLA guarantees, and proactive infringement detection, in close partnership with legal and policy teams.
• Provide technical leadership across the team: drive design reviews, set engineering standards, and mentor engineers.
• Shape the team's technical roadmap with a focus on scalability, reliability, and measurable governance outcomes (e.g., violation catch rate, takedown SLA, review efficiency, seller and rights-holder experience).
• Partner closely with product managers, policy/operations/legal teams, and algorithm engineers to turn governance and IP policies into effective, low-friction technical solutions.
• Drive pragmatic adoption of LLM and agent-based capabilities in review and takedown workflows where they measurably improve accuracy, coverage, or efficiency.

Minimum Qualifications:

• Bachelor's degree or higher in Computer Science or a related technical field.
• 5+ years of experience building highly scalable backend services and distributed systems.
• Demonstrated technical leadership: leading complex projects end-to-end, driving architecture decisions, or mentoring engineers.
• Ability to communicate complex technical concepts effectively to both technical and non-technical stakeholders.

Preferred Qualifications:

• Experience in E-commerce or marketplace platforms, especially listing/catalog systems.
• Experience in IP protection, brand protection, anti-counterfeiting, or trust & safety domains; familiarity with notice-and-takedown processes (e.g., DMCA).
• Experience designing and deploying LLM or agent based solutions with proven, measurable business or engineering impact.
• Experience working with global, cross-timezone teams.
