Location: Singapore
Workplace: Onsite
Employment Type: Internship
Job Function: Data Science & Machine Learning
Seniority: Intern level

Key Responsibilities

  • •Enhance the multimodal perception encoder, including exploring adaptive frame rates beyond a fixed frame rate.
  • •Investigate multimodal integration of audio and user behavior to improve perception.
  • •Develop approaches to fuse multimodal perception with reasoning to improve comprehensive cognitive abilities.
  • •Apply and evaluate LLM training/adaptation methods or code intelligence techniques to advance research objectives.
  • •Conduct hypothesis-driven experiments with reproducible results and clear reporting.

Key Requirements

  • •PhD or Master’s degree in Computer Science, Machine Learning, NLP/CV, Systems, or related fields (or equivalent research experience).
  • •Strong programming and debugging skills in Python and/or C/C++ with solid data structures and algorithms fundamentals.
  • •Hands-on experience with at least one: LLM/generative AI training or adaptation, code intelligence, or agentic systems (tool-use, planning, multi-step reasoning).
  • •Strong experimental rigor with hypothesis-driven iteration, reproducibility, and clear communication.
  • •Exposure to relevant research areas such as long-context modeling/retrieval or RLHF/verifier-based RL/preference optimization for code tasks is a plus.
