Sr AI Engineer II - Enterprise Architecture
About The Position
At American Express, AI is reshaping commerce and customer experiences. Within Amex Technology, teams are building platforms, products, and governance for agentic AI systems to operate responsibly and at scale. The focus is on intelligent, adaptive systems that can plan, reason, and act across complex workflows while meeting financial-services standards for security, explainability, reliability, and compliance. As a Senior AI Engineer, Agentic AI, you will turn complex and ambiguous problems into production-grade agentic systems that operate on financial data, serve customers, and satisfy regulatory requirements. You will work end to end, from shaping solutions with product and design partners to building and shipping production code and owning systems after launch. The role covers customer-facing LLM-powered features, agentic systems that automate financial workflows, and internal AI capabilities that help engineers build with AI safely and efficiently. This is a hands-on engineering role rather than a research-only position, requiring autonomy, sound judgment, and technical innovation within a regulated financial environment. The role operates in a modern enterprise-scale environment using Python, Go, and TypeScript; AWS and/or GCP; Kubernetes; REST and gRPC APIs; and event-driven distributed systems such as Kafka. The AI environment includes commercial and open-source LLMs, agent orchestration, retrieval-augmented generation, vector storage, evaluation, and strong schema, validation, and state-management practices. Engineers use AI-assisted and agentic workflows for design, implementation, testing, debugging, and refactoring while maintaining production-quality standards. Systems must meet high standards for reliability, security, and auditability. American Express describes its culture as grounded in innovation, shared values, leadership behaviors, and commitment to customers, communities, and colleagues. The company offers opportunities to learn, develop as a leader, and grow a career, along with benefits supporting physical, financial, and mental well-being. The position may be onsite, hybrid, or virtual depending on the role and business need. The expected salary range is referenced, but no numerical range is included in the posting.
