American Express is at the forefront of reshaping commerce and redefining customer experiences through Artificial Intelligence. Within Amex Technology, we are building platforms, products, and governance to enable agentic AI systems to operate responsibly and at scale across the enterprise.

Our focus is on agentic AI development, designing intelligent, adaptive systems capable of planning, reasoning, and acting across complex workflows with appropriate autonomy. These systems power autonomous workflows, decision support, and customer-facing experiences, while adhering to the stringent standards for security, explainability, reliability, and compliance required in financial services.

We collaborate closely with product, design, and business teams to deliver agentic capabilities that reduce operational friction, enhance decision-making, and transform customer interactions, transactions, and growth.

The Role

As an AI Engineer I - Agentic AI, you will be a hands-on contributor to the development of production agentic AI systems operating on real financial data and serving real customers. You will work alongside experienced engineers, product managers, and designers to design, build, and ship AI-powered features, learning to operate within a regulated, customer-facing environment. This role offers strong mentorship and opportunities to deepen your technical expertise in LLMs, agentic systems, and production AI engineering. This is not a research-only position; you will write production code, contribute to system design, and assist in operating the systems you build post-launch, with guidance from senior engineers.

What You'll Do

• Contribute to the design and implementation of LLM-powered and agentic product features.
• Build and extend agentic AI workflows that reason over context, call tools, and perform actions under guidance from senior engineers.
• Assist in implementing and maintaining retrieval-augmented generation (RAG) pipelines over financial data, with a focus on correctness and safety.
• Contribute to shared AI infrastructure, including LLM services, orchestration components, and evaluation/monitoring tooling.
• Participate in the operation of AI systems in production, including monitoring, debugging, and enhancing reliability and performance.
• Collaborate closely with product and design partners, learning to translate customer needs into technical solutions.

Technical Environment

We seek candidates excited to grow in a modern, enterprise-scale engineering environment focused on agentic AI, rather than a narrow checklist.

Core engineering stack

• Languages: Python, Go, TypeScript
• Cloud and infrastructure: AWS and/or GCP, Kubernetes
• APIs and services: REST, gRPC
• Distributed systems: event-driven architectures, including Kafka

Agentic AI and ML

• Commercial and open-source LLMs integrated into agentic workflows
• Tooling for agent orchestration, retrieval-augmented generation, vector storage, and evaluation
• Schema validation and structured data handling

AI-assisted development

• Utilize AI-assisted and agentic development tools for design, implementation, testing, debugging, and refactoring.
• Learn to apply these tools responsibly while maintaining production-quality standards.
• All systems are built to meet high standards for reliability, security, and auditability, reflecting the responsibility of deploying autonomous AI in a financial services environment.

What We're Looking For

• 3+ years of professional software engineering experience.
• Some hands-on experience building or contributing to AI-powered features, LLM-based applications, or applied ML systems (professional or project-based).
• Solid engineering fundamentals in at least one backend language (Python, Go, or TypeScript).
• Familiarity with APIs, basic cloud concepts, and modern development practices.
• Interest in agentic AI systems, autonomy, and AI-assisted development workflows.
• Willingness to learn, take feedback, and grow technical ownership over time.
• Comfort working in collaborative, cross-functional teams.
• A strong customer mindset and curiosity about real-world problem solving.

Preferred Qualifications

• Exposure to LLM tooling, prompt engineering, RAG, or agent frameworks through work, coursework, or personal projects.
• Internship or early-career experience in fintech or other regulated environments.
• Contributions to open-source projects, hackathons, or side projects related to AI or developer tooling.

We provide benefits supporting your holistic well-being: competitive base salaries, bonus incentives, financial well-being and retirement support, comprehensive medical, dental, vision, life insurance, and disability benefits, flexible working models, generous paid parental leave, access to global on-site wellness centers, confidential counseling support, and career development/training opportunities.
