Job DescriptionJoining Amex Tech means discovering and shaping your contribution to something big. Here, you can work alongside talented technology teams and build a unique career with the Powerful Backing of American Express. With opportunities to work with the latest technologies and a commitment to supporting the broader engineering community, our mission is to power your success. Amex Tech is powered by our technology, our culture, and our colleagues.
The U.S. Consumer Services and Membership Digital Experiences Technology team (USCDT) brings together foundational strategic technology capabilities across digital experience engineering, marketing and advertising technology, enterprise communications, travel and lifestyle, and dining technology. The organization builds customer-facing capabilities that deepen digital engagement as well as core technology platforms that span business lines and customer segments.
American Express Global Dining brings together world-class experiences through platforms such as Resy, Tock, and Rooam, creating seamless connections between diners, restaurants, and the broader American Express Membership ecosystem. Our mission is to define the future of hospitality and dining through technology, data, and design.
As part of Team Amex, you'll have the support, flexibility, and autonomy to make an impact while helping shape the future of how people discover, book, and enjoy dining experiences worldwide.
At American Express, AI is reshaping the future of commerce and redefining the experiences our customers, merchants, and Card Members expect. Within Global Dining, housed within Amex Technology, we are applying AI to reimagine how diners discover and experience restaurants, how restaurants engage and serve their guests, and how our colleagues build and operate the platforms behind those experiences.
Our focus is increasingly on agentic AI: intelligent systems capable of understanding context, reasoning, planning, using tools, and taking actions across complex workflows with appropriate levels of autonomy. These capabilities have the potential to transform dining discovery, reservations, restaurant operations, customer servicing, and the engineering systems that power the Global Dining ecosystem.
We are building these capabilities with the reliability, security, explainability, observability, and governance required to operate AI at American Express scale.
THE ROLEAs a Senior AI Engineer - Agentic AI, Global Dining, you will be a hands-on engineer responsible for designing, building, integrating, and operating AI-powered capabilities across the Global Dining ecosystem.
You will develop production AI systems that apply large language models, retrieval, tools, orchestration, machine learning, and generative AI to real-world customer, restaurant, and platform workflows. You will work across the AI application stack-from LLMs, retrieval and agent orchestration to APIs, data pipelines, evaluations, observability, and production infrastructure.
This is a deeply hands-on engineering role. You will write production code, prototype emerging approaches, contribute to technical designs, and take AI capabilities from experimentation through deployment, monitoring, and continuous improvement. You will collaborate with engineers across teams to integrate AI models and intelligent services into existing production systems while meeting both technical and business requirements.
As a Senior Engineer, you will provide technical guidance within the team, contribute to engineering standards and reusable patterns, mentor junior engineers, and help foster a culture of engineering excellence and innovation. You will apply advanced expertise in AI engineering while continuing to develop breadth across adjacent technical domains.
You will partner closely with Product, Design, Data, Information Security, Risk, Compliance, and other engineering teams to translate business and customer needs into responsible, scalable AI solutions.
