Key Responsibilities

  • •Build and evolve the agent runtime (harness/agent loop) powering creator/seller agents by orchestrating skills, tools, and context.
  • •Engineer context and memory for long multi-turn agents, including structured note-taking, context compaction/summarization, and retrieve-then-load retrieval.
  • •Post-train and fine-tune LLMs (SFT/DPO/RL) and build a data flywheel that turns served conversations into training/eval/retrieval signals.
  • •Design and integrate tools, Skills, and MCP connectors (tools-as-APIs), including skill/tool search for large tool inventories.
  • •Build evaluation harnesses (LLM-as-judge with human calibration) and regression/safety/cost/latency-aware tests to close the offline-to-online gap.

Key Requirements

  • •Currently pursuing a PhD in Software Development, Computer Science, Computer Engineering, or a related technical discipline.
  • •Strong Python 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 side project).
