Most “AI architect” roles turn out to be a chatbot pilot. This one isn’t.

A Fortune 500 financial technology company is building its enterprise GenAI platform, and they need someone to own the API layer it all runs through — the layer where LLM applications, agent workflows and intelligent automation actually reach the business.

Alpharetta, GA — onsite, 5 days

Contract · C2C · Long-term

10 years, with hands-on GenAI delivery

What they need to see:

• API-first architecture at scale — REST, GraphQL, gateway patterns, governance
• Real GenAI delivery: LLM integration, RAG pipelines, vector databases
• Agent frameworks — LangChain, LlamaIndex or equivalent
• Hands‑on .NET / C#
• Azure or AWS, plus Docker, Kubernetes, CI/CD

This is an architecture ownership role. You set the standards, you chair the reviews, and your work is visible to the business.
