Principal Agentic Engineer, AI Ecosystem

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Principal Agentic Engineer, AI Ecosystem based in the United States. The Principal Agentic Engineer will define and build the technical foundations of an organization-wide AI ecosystem, connecting AI platforms, developer tooling, and agentic product development. This Principal-level role combines strategic architecture ownership with hands-on engineering, ensuring that shared capabilities are designed consistently rather than developed independently across teams. You will establish reusable agent standards, execution frameworks, identity and authorization models, and evaluation infrastructure that enable safe, reliable, and scalable agent deployment. Working across multiple engineering groups and Product leadership, you will take ownership of critical technical challenges that fall between existing team responsibilities. You will also shape the long-term vision for an AI-native developer ecosystem while building and shipping foundational components yourself. This is an opportunity to influence technical direction at scale through architecture, prototypes, production code, and engineering mentorship.
