Principal AI Engineer & AI Engineer | Agentic AI / LLM

Hiring: Principal AI Engineer & AI Engineer | Agentic AI / LLM

We’re looking for hands-on AI Engineers and Staff/Principal-level AI Engineers to build and productionize next-generation Agentic AI and Generative AI solutions for enterprise environments.

These are engineering-heavy roles for candidates who have actually built and deployed LLM/Agentic AI systems into production — not just prompt engineering, research, or basic chatbot/API integrations.

Location: New York City, NY — Hybrid, 3 Days Onsite/Week

Work Hours: EST overlap required

What We're Looking For

We want engineers who can demonstrate real production ownership, including:

✅ Built and deployed production LLM applications

✅ Built production Agentic AI systems

✅ Strong RAG implementation experience

✅ Hands-on MCP and tool-calling experience

✅ Strong Python engineering

✅ Experience with embeddings, chunking & vector databases

✅ Experience optimizing AI systems for latency, cost and token usage

✅ Ability to own AI systems end-to-end

Profiles focused primarily on prompt engineering, academic research, basic chatbots, or simple LLM API integrations are not the target for these positions.
