Custom AI & LLM Systems Engineer

Design and deploy production-grade agentic workflows, enterprise hybrid RAG pipelines, low-latency streaming endpoints, and automated prompt evals using Python, LangChain, and vector stores.

WHAT YOU WILL OWN

Key Responsibilities

  • Build production-ready Agentic AI systems with autonomous tool calling, self-correction, and structured outputs.
  • Engineer low-latency hybrid RAG pipelines combining dense embeddings (pgvector/Pinecone) with sparse keyword retrieval.
  • Develop streaming inference endpoints with FastAPI, WebSockets, and PII masking for enterprise privacy compliance.
  • Benchmark model evaluations (Ragas / LangSmith), conduct regression testing, and fine-tune open-weight models.
  • Integrate frontier LLMs (Claude 3.5, OpenAI, DeepSeek, Llama 3) into enterprise SaaS backbones.
  • Write automated evaluation scripts to detect hallucination, measure retrieval recall, and optimize latency.
WHAT YOU BRING

Skills & Qualifications

  • 3+ years of production software engineering with 2+ years dedicated to AI/ML or LLM engineering.
  • Strong mastery of Python, async programming, FastAPI, LangChain / LlamaIndex, and vector databases.
  • Practical experience with embedding models, token optimization, prompt caching, and context management.
  • Strong foundation in distributed systems, API security, and containerized deployment on cloud infrastructure.
  • Continuous passion for following frontier AI research and translating experimental papers into real systems.
