Agentic AI Architect / Lead Developer

Location: Charlotte, NC (preferred for hybrid work; open to remote for strong candidates)

Long term


Build and ship production agentic AI featuresagents, tools, prompts, evals, and integrations — against an established reference architecture.


Required Qualifications:

  • Experience in software development or data engineering
  • Hands-on experience in Generative AI or LLM-based applications
  • Experience building APIs, microservices, or distributed systems
  • Bachelor’s or Master’s degree in Computer Science, AI/ML, Data Science, or related field


Key roles:

  • Implement agents and sub-agents (planner, executor, critic, router) using Claude Agent SDK / Lang Graph
  • Build tools and MCP integrations, design clean tool schemas, idempotent operations, and robust error handling.
  • Implement RAG pipelines: ingestion, chunking, embedding (Bedrock Titan), hybrid retrieval, citation rendering.
  • Develop Fast API/Python services exposing agent capabilities (sync + streaming); integrate with SQL (Postgres) and object stores (S3).
  • Write evaluation harnesses (golden sets, regression suites, LLM-as-judge) and trace/observe agent runs.
  • Implement guardrails: input/output validation, schema enforcement, rate limiting, prompt-injection defenses.
  • Participate in code reviews, pairing, and architecture discussions; own quality of the code you ship.
  • Strong Python (FastAPI, async, Pydantic) or Node/TypeScript equivalent.
  • Hands-on with at least one agent framework (Claude Agent SDK / Lang Graph / AutoGen).
  • Practical experience with LLM tool/function calling, structured outputs, streaming.
  • RAG implementation experience (pgvector / FAISS / OpenSearch).
  • Git, CI/CD, containerization (Docker), and cloud basics (AWS preferred).


Roles/Responsibilities:

  • Implement single-agent and multi-agent systems using frameworks such as LangChain, Semantic Kernel, CrewAI, AutoGen, or similar
  • Build applications using LLMs (Azure OpenAI, OpenAI, Anthropic, etc.)
  • Implement Retrieval-Augmented Generation (RAG) pipelines
  • Enable agents to coordinate and collaborate in multi-agent ecosystems
  • Build secure, scalable APIs and microservices to support AI agents
  • Develop evaluation frameworks for agent performance (accuracy, hallucination detection, response quality)
  • Monitor system behavior and continuously improve reliability
  • Optimize performance for latency, cost, and scalability
