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

Key Responsibilities

  • •Build and evolve agent runtime (harness/agent loop) orchestrating skills, tools, and context for creator/seller agents.
  • •Engineer context & memory for long multi-turn agents, including agentic memory, context compaction/summarization, masking, and retrieve-then-load retrieval.
  • •Post-train and fine-tune LLMs (SFT/DPO/RL) and build a data flywheel from served conversations into training/eval/retrieval signals.
  • •Design and integrate tools/skills/MCP connectors (tools-as-APIs), including skill/tool search for large inventories.
  • •Build evaluation harnesses and a self-evolving replay loop to continuously improve systems, then ship high-leverage end-to-end surfaces to production across 30+ languages.

Key Requirements

  • •Complete or recently completed a PhD in CS/AI/Math (or a quantitative field).
  • •Strong Python experience plus one of C++/Go/Rust/Java.
  • •Solid ML/DL/NLP fundamentals with hands-on experience with LLMs or agents (research, internship, competition, open-source, or a serious project).
  • •Ability to read a paper or engineering blog and turn it into working code.
  • •State availability and graduation date clearly; be able to commit to an onboarding date by the end of the year.
