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.

What We’re Looking For

• 5+ years of software engineering experience, including meaningful production experience with LLMs or applied ML systems.

• A track record of shipping AI-powered or agentic systems that real users depend on.

• Strong engineering fundamentals across backend systems, APIs, data pipelines, and cloud infrastructure.

• Hands-on experience with modern LLM tooling and agentic patterns and architectures.

• Fluency with AI-assisted and agentic development workflows.

• 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.

Preferred Qualifications

• 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.

Depending on factors such as business unit requirements, the nature of the position, cost and applicable laws, American Express may provide visa sponsorship for certain positions.
