Full Job Description
Job Description

As a Senior AI Engineer II - 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 You'll Do

  • Design, build, and ship LLM-powered and agentic product features that change how customers manage their finances.


  • Build agentic AI systems that reason over context, invoke tools, take real actions, and recover gracefully from failure.


  • Architect and implement production-grade RAG pipelines over sensitive financial data, with strict requirements for correctness, auditability, and safety.


  • Contribute to shared AI infrastructure, including LLM services, agent orchestration frameworks, and evaluation and monitoring tooling, that scales agentic development across Amex Technology.


  • Own the systems you build in production, including reliability, latency, cost, and failure modes.


  • Work closely with product and design partners; engineers in this role are expected to think in terms of customer outcomes, not just technical execution.


Technical Environment

We don't hire to a narrow checklist, but candidates should be comfortable operating in a modern, enterprise-scale environment with a strong emphasis on agentic AI.

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


  • Strong schema, validation, and state management practices


AI-assisted development

  • Fluency with AI-assisted and agentic development workflows for design, implementation, testing, debugging, and refactoring


  • Thoughtful use of these tools while maintaining production-quality engineering 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.


Qualifications

  • 8+ 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.
