About the role

What will you do at American Express?

At American Express, AI is reshaping the future of commerce and redefining the

experiences our commercial customers and card members expect. 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.

We partner closely with product, design, and business teams to deliver agentic

capabilities that reduce operational friction, improve decision-making, and

transform how customers interact, transact, and grow.

The Role

As a Senior AI Engineer – Agentic AI, you will be a core builder responsible for

turning complex, ambiguous problems into production-grade agentic systems that

operate on real financial data, serve real customers, and meet real regulatory

requirements.

You will work end to end: shaping solutions with product and design, building

and shipping production code, and owning what you deliver after launch. 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.

This is not a research-only role. We are looking for engineers who are

comfortable operating with autonomy, exercising sound judgment, and pushing the

technical envelope within the realities of a regulated financial environment.
