Location: Singapore
Employment Type: Internship
Job Function: Research & Scientific (R&D)
Seniority: Intern level

Key Responsibilities

  • •Build and optimize the search-domain LLM foundation by integrating search knowledge and refining post-training pipelines (e.g., long-text pre-training and multimodal representations).
  • •Contribute to agent engineering, including the Agent execution framework (Harness) for tool calling, planning, memory, and environment interaction, plus multi-agent scheduling and collaboration.
  • •Work on long-term memory mechanisms and closed-loop self-improvement/RSI research, including automated hyperparameter tuning and training pipeline automation.
  • •Help develop reward/verifier systems and automated evaluation frameworks for complex long-cycle tasks and cross-domain capabilities, including multi-agent evaluation standards.
  • •Support business implementation areas such as long-horizon task agents, multimodal AIGC creation, and visual search/on-device intelligence (e.g., object detection and OCR).

Key Requirements

  • •Currently pursuing a Bachelor's degree or above in Computer Science or a related major.
  • •Strong foundation in machine learning/deep learning and familiarity with cutting-edge LLM and agent technologies.
  • •Experience with LLM/agent projects such as pre-training, fine-tuning/alignment, tool calling, planning, memory, multi-agent collaboration, RAG, RLHF/RLAIF, data synthesis, and automated evaluation.
  • •Familiarity with PyTorch or TensorFlow for training and deployment, including distributed training, mixed-precision training, and model compression/inference acceleration (e.g., quantization, pruning, distillation, TensorRT).
  • •Familiarity with big data frameworks and applications such as MapReduce and Spark (plus).
