Location: Singapore
Employment Type: Full time
Job Function: Research & Scientific (R&D)
Seniority: Graduate level

Key Responsibilities

  • •Build global product catalog and content understanding systems using structured and semantic representations for products, videos, images, merchants, and brands.
  • •Develop algorithms for identical product matching, product/merchant/brand deduplication, and cross-lingual product aggregation with multimodal matching and semantic alignment.
  • •Build pricing algorithms for price comparison, product pricing, price monitoring, and anomaly detection, supporting subsidy programs and competitiveness analysis.
  • •Construct multimodal semantic links across video-product, product-product, and video-video relationships to enable trend understanding, product mining, and AIGC generation.
