BlackCube Labs; Pennington (NJ); On-site; USD 76,000 - 87,000; Full time

Job summary

Genesis10 is seeking a Senior AI Engineer (Generative AI & Agentic Systems) for a 12+ month contract position in Pennington, NJ. You will architect and scale production-grade LLM applications with agentic frameworks.

Responsibilities include building RAG pipelines, multi-agent workflows, and robust LLM integration using LangChain, LangGraph, LangSmith, and Deepagents, while optimizing cost and latency. Strong Python and cloud experience required.

Qualifications

• Advanced, production-level proficiency in Python (asyncio, design patterns, profiling, and testing).
• Hands-on production experience with LangChain, LangGraph, LangSmith, and Deepagents.
• Deep knowledge of RAG pipelines, prompt engineering, and vector databases (Pinecone, Weaviate, Milvus, Qdrant, pgvector).
• Familiarity with major LLM providers and function-calling architectures.
• Experience with Git, CI/CD pipelines, containerization (Docker), and cloud environments (AWS, GCP, or Azure).

Responsibilities

• Architect and scale advanced Retrieval-Augmented Generation (RAG) pipelines, including custom chunking, hybrid search, embedding optimization, and reranking mechanisms
• Build complex, stateful multi-agent systems and autonomous workflows using frameworks such as LangGraph and Deepagents
• Orchestrate and monitor using LangChain for robust LLM integration and LangSmith for tracing, evaluation, debugging, and performance monitoring of production LLM pipelines
• Write clean, modular, highly efficient Python code adhering to modern standards (asynchronous programming, strict typing, robust error handling)
• Connect LLM agents and workflows with external data sources, enterprise APIs, vector databases, and developer tooling
• Optimize token usage, latency, and operational costs across LLM-driven applications without compromising response quality or accuracy
