Enterprise Agent Control PlaneBuild a unified control plane for managing agents across heterogeneous execution environments and AI providers.
Develop APIs and services for agent registration, configuration, deployment, versioning, lifecycle management, policy enforcement, and runtime management.
Create abstractions that reduce provider-specific complexity while preserving access to differentiated capabilities across AI ecosystems.
Agent Governance & SecurityEngineer platform-level controls for enterprise AI governance, including agent identity, authentication and authorization, tool permissions, policy enforcement, data boundaries, auditability, and lifecycle controls.
Build mechanisms for governing models, prompts, tools, MCP servers, knowledge sources, agent-to-agent interactions, and external integrations.
Partner with security, risk, privacy, and governance teams to translate enterprise requirements into scalable technical controls.
Agent Discovery & EcosystemBuild registries and catalogs that allow developers and AI systems to discover reusable agents, tools, skills, prompts, models, knowledge sources, and other platform capabilities.
Develop metadata, ownership, versioning, dependency, certification, and discovery mechanisms that enable a healthy enterprise agent ecosystem.
Agent ObservabilityBuild end-to-end telemetry for agent execution, including traces, events, model interactions, tool calls, latency, token consumption, cost, failures, policy decisions, and quality signals.
Develop capabilities that make complex and multi-agent workflows explainable and debuggable.
Enable platform and application teams to understand agent behavior across multiple models, runtimes, tools, and external systems.
Evaluation & Continuous LearningDevelop evaluation frameworks for measuring agent quality, reliability, safety, and task performance.
Build automated evaluation pipelines incorporating offline evaluations, production signals, human feedback, regression testing, and experimentation.
Help create continuous learning loops that turn production telemetry and feedback into actionable improvements to agents, prompts, tools, models, and platform capabilities.
Developer ExperienceBuild SDKs, APIs, CLIs, templates, local development environments, and self-service workflows that make agent development simple and productive.
Create opinionated paved roads that allow developers to move quickly while automatically incorporating enterprise security, governance, observability, and operational standards.
AI CI/CD & Platform EngineeringBuild CI/CD capabilities specifically designed for AI agents, including automated evaluation, policy validation, security checks, artifact/version management, deployment, promotion, rollback, and release controls.
Design GitOps and infrastructure-as-code patterns for deploying and managing agent workloads.
Help establish engineering standards for taking agents from experimentation to production safely and repeatedly.
Responsibilities- Design and implement highly scalable components of the enterprise Agentic AI Platform.
- Own complex technical problems from architecture through production implementation and operation.
- Build distributed services and APIs supporting agent execution and lifecycle management.
- Develop integrations with major AI/model ecosystems and managed agent platforms.

What Success Looks LikeYou will help make it possible for developers across American Express to move from an agent idea to a governed production deployment through a consistent, self-service platform.
Successful platform capabilities will make the secure and reliable path the easiest path: developers should be able to build once and operate agents across multiple AI ecosystems while receiving governance, identity, observability, evaluation, deployment, and operational capabilities by default.
You will play a key role in establishing the engineering foundations for an enterprise ecosystem in which AI agents can be
built, discovered, trusted, governed, observed, evaluated, deployed, and continuously improved at scale.
Depending on factors such as business unit requirements, the nature of the position, cost and applicable laws, American Express may provide visa sponsorship for certain positions.
