Job Responsibilities
- Build and evolve the agent runtime (harness / agent loop) powering our creator / seller agents - orchestrate skills, tools, and context.
- Engineer context & memory for long multi-turn agents - agentic memory (structured note-taking), context compaction / summarization, context editing / observation masking, and just-in-time (retrieve-then-load) retrieval.
- Post-train and fine-tune LLMs (SFT / DPO / RL) and build the data flywheel that turns served conversations into training / eval / retrieval signals.
- Design and integrate tools, Skills, and MCP connectors (tools-as-APIs), plus skill / tool search for large tool inventories.
- Build evaluation - LLM-as-judge with human-agreement calibration; regression / safety / cost / latency-aware harnesses; close the offline↔online gap.
- Build the self-evolving loop - replay + task/environment simulator + Auto-RCA / Auto-GSB / Auto-Policy - so the system continuously improves itself.
- Own one high-leverage end-to-end surface and ship it to production across 30+ languages, measured on real business metrics (GMV, Content, Creator/Merchant satisfaction).
Qualifications
Minimum Qualifications
- Individuals who are completing or have recently completed a Bachelor's degree or Master's degree in CS / AI / Math or a quantitative field.
- Strong Python plus one of C++ / Go / Rust / Java
- Solid ML / DL / NLP fundamentals, with genuine hands-on experience with LLMs or agents (coursework, research, internship, competition, open-source, or a serious side project)
- Able to read a paper or an engineering blog and turn it into working code.
Preferred Qualifications
- Have built the runtime, not just called an API - even at research / hobby / competition scale: your own agent loop / harness, a memory / context-management system, a RAG or tool-use agent, or a fine-tuned / post-trained model
- Hands-on experience in any one of: post-training (SFT / DPO / RLHF / RLAIF / RLVR, reward modeling); agent systems (harness, context engineering, MCP / Skills, sub-agents, tool search); evaluation (LLM-as-judge, τ-bench / SWE-bench / GAIA / BFCL); inference & serving (vLLM / TensorRT-LLM, MoE, KV / prompt caching); or multilingual NLP - depth in one is enough, breadth welcome
