## About the Role

This is an individual contributor, hands-on, deeply technical role with broad architectural ownership and high organizational impact; however, as the team grows, you will take on increasing responsibility for technical leadership and people development within the agentic AI space. Mentoring, developing and managing direct reports may be in scope for some of our opportunities.

 * 12+ years of experience building large-scale distributed systems + strong experience with LLM systems, agentic workflows or advanced ML infrastructure
 * Proven ownership of complex, cross-cutting agentic systems spanning multiple teams or products.
 * Strong engineering fundamentals across backend systems, APIs, data pipelines, and cloud infrastructure.
 * Deep experience across the agentic AI stack, including planning, tool use, memory, and evaluation.
 * Fluency with AI-assisted and agentic development workflows.
 * Comfort operating in ambiguous problem spaces and translating them into shipped, reliable autonomous systems.
 * Ability to influence technical direction and align teams without formal authority.
 * Experience in workflow engines, async processing, queues, and streaming systems., * Experience building agentic systems in fintech or other regulated industries.
 * Experience as a founding engineer or early technical leader in AI-driven products.
 * Demonstrated success delivering technically complex autonomous systems that customers actively rely on.
 * Meaningful contributions to open-source AI or agentic frameworks. Familiarity with fine-tuning, model optimization and inference pipelines is a plus

## Description

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.

As a Staff Data Engineer - Agentic AI, you will operate as a senior individual contributor within Amex Technology, helping define how agentic AI systems are designed, built, and operated across the company.

You will work at the intersection of agentic system architecture and hands-on execution: designing core frameworks, writing production code, reviewing critical designs, and guiding teams through complex technical decisions. This role does not include people management; your impact comes from technical leadership, sound judgment, and the ability to turn ambiguity into reliable, scalable agentic systems.

You will work closely with Product and UX partners to shape a shared vision for agentic AI experiences. While product teams own prioritization, Staff engineers are expected to actively influence what gets built and how agentic systems come together across teams., We back our colleagues with the support they need to thrive, professionally and personally. That's why we have Amex Flex, our enterprise working model that provides greater flexibility to colleagues while ensuring we preserve the important aspects of our unique in-person culture. Depending on role and business needs, colleagues will either work onsite, in a hybrid model (combination of in-office and virtual days) or fully virtually.
