Within Amex Technology, we are building platforms, products, and governance that enable agentic AI systems to operate responsibly and at scale across the enterprise.

Our focus is on agentic AI development: designing intelligent, adaptive systems that can plan, reason, and act across complex workflows with appropriate levels of autonomy. These systems power autonomous workflows, decision support, and customer-facing experiences - while meeting the high standards for security, explainability, reliability, and compliance required in financial services.

The scope of this role spans customer-facing LLM-powered features, agentic systems that automate financial workflows, and internal AI capabilities that enable other engineers to build with AI safely and efficiently.

Strong sense of ownership and sound technical judgment.

Comfort operating with ambiguity and turning it into shipped reliable product.

A strong product mindset and customer orientation.

Experience building agentic systems in fintech or other regulated industries.

Experience as a founding engineer or early technical contributor in high-growth environments.

Demonstrated ability to ship technically complex systems in regulated contexts that customers actively rely on.

Meaningful open-source contributions, particularly in AI or developer tooling.
