About the Role

------------------


We are seeking an experienced

LLM Algorithm Tech Lead

to drive the design of AI intelligence architecture and lead the end-to-end application of large language models in real-world product environments. This role focuses on

reasoning capability design, intelligent behavior frameworks, knowledge/RAG pipelines, inference optimization, and cross-team engineering collaboration

.


You will architect the core intelligence layer behind next-generation AI products and ensure LLM capabilities can be reliably, safely, and efficiently applied in production.

Key Responsibilities

------------------------

Intelligence Architecture Design

Design LLM reasoning frameworks: task decomposition, structured reasoning, and decision logic Architect intelligent behavior modules including context handling, memory mechanisms, and proactive insights Define the capability roadmap and build modular, extensible intelligence components

Applied LLM System Development & Production Integration

Lead the full lifecycle of LLM-powered features: requirement design prototyping production Optimize model outputs for reliability, consistency, controllability, and domain suitability Implement hallucination mitigation strategies via prompting, constraints, and structured reasoning

Knowledge Integration & RAG Pipelines

Build multi-source retrieval pipelines for structured and unstructured data Own chunking, embedding, reranking, and context-injection strategies Ensure RAG-enhanced reasoning is stable and production-grade

Inference Optimization & Model Strategy

Evaluate and select LLMs (OpenAI, Claude, DeepSeek, Qwen, Llama, Gemini, Mistral) Build model-routing logic based on latency, cost, performance, and task type Work with engineering to optimize runtime, memory usage, and system availability

Cross-Functional Collaboration

Partner with engineering, product, and data teams to deliver high-quality LLM features Define evaluation standards, monitoring metrics, fallback strategies, and safety constraints Lead issue investigation and optimization in production systems
