About the Role

Remote position open to candidates in the USA. CryptoCurrency ICO/Airdrop is building the most advanced AI Agent for the Web3 industry and is seeking a Core Algorithm Engineer to architect AI Agent systems, optimize end‑to‑end RAG pipelines, implement LLM training/alignment, and deploy scalable solutions.

Responsibilities

• Develop AI Agent Systems: Build intelligent search and task execution agents using ReAct, planning, and multi‑agent frameworks (e.g., LangGraph, Dify, CrewAI).
• Optimize End‑to‑End RAG Pipelines: Build and refine efficient RAG systems from ingestion, chunking, and embedding to hybrid vector search (OpenSearch), implementing precise grounding and citation.
• LLM Training & Alignment: Conduct advanced post‑training (SFT, RLHF, continual pretraining) and align models for reliable JSON‑schema function calling and external tool usage.
• Automated Evaluation & Iteration: Build offline/online evaluation pipelines using synthetic QA, retrieval metrics, and hallucination detection to continuously improve system performance and stability.

Skills / Requirements

• Bachelor's or Master's degree in Computer Science, AI, Machine Learning, or a related field.
• 3+ years of experience developing AI systems, with a focus on RAG, agent architectures, or LLM training/optimization.
• Proficiency in Python and key ML frameworks (PyTorch/TensorFlow), with experience in distributed training and high‑performance inference.
• Hands‑on, in‑depth experience in at least two of the following domains:
  • End‑to‑end RAG pipeline development and optimization with OpenSearch/vector databases.
  • AI Agent framework development (LangGraph, CrewAI, ReAct).
  • Advanced LLM training (SFT, RLHF, LoRA) and alignment techniques.
• Excellent problem‑solving and systems thinking skills.
• Passion for Web3 and AI is a plus.
