PhD-Driven Multimodal LLM Engineer Intern

ByteDance; Singapore; On-site; SGD 28,000 - 50,000; Part time

Job summary

ByteDance is seeking a Multimodal LLM Algorithm Engineer Intern for a 2027 start in Singapore. You will contribute to global e-commerce content understanding, knowledge graphs, and multimodal model development within a dynamic internship program.

You will join the Global E-commerce Algorithm team to build catalog systems, cross-lingual product aggregation, pricing intelligence, and AIGC-enabled search and recommendation. Strong research and PyTorch/TensorFlow experience are valued.

Qualifications

• Pursuing a PhD in Software Development, Computer Science, Computer Engineering, or a related technical discipline.
• Strong research or practical experience in NLP, CV, generative models (e.g. Diffusion，GANs，ControlNet) , multimodal learning, large models, or Agents.
• Proficiency in PyTorch / TensorFlow and hands-on experience in model training, tuning, and deployment.

Responsibilities

• Build global product catalog and content understanding systems, modeling products, videos, images, merchants, and brands with structured and semantic representations.
• Develop algorithms for identical product matching, product/merchant/brand deduplication, and cross-lingual product aggregation, addressing multimodal matching, real-time aggregation, multi-granularity clustering, and semantic alignment.
• Build pricing algorithms for price comparison, product pricing, price monitoring, and anomaly detection, supporting subsidy programs, price competitiveness analysis, and supply optimization.
• Construct multimodal semantic links across video-product, product-product, and video-video relationships to support trend understanding, product mining, AIGC generation, and content-commerce supply optimization.
• Explore next-generation generative search and recommendation through full-format representation learning and SID modeling across videos, livestreams, products, and queries.
• Design and develop generative algorithms tailored for high engaging, high conversion e-commerce visual creatives, solving challenges in identity-preserving and aesthetic style consistency to produce production-grade intelligent background synthesis，virtual try-on, and localised lifestyle scene generation.
• Explore business-facing Agents such as price comparison Agents, product analysis Agents, content AIGC Agents, and merchant operation Agents, leveraging RAG, tool calling, planning, reasoning, and automated evaluation.
• Own the end-to-end algorithm workflow, including data construction, model training, evaluation, deployment, badcase analysis, and continuous iteration.
