Job Description

You’ll shape how products are built.

Our engineers understand not just how technology works, but how it shapes everyday experiences. Strong execution and clear-thinking drive how we build products that are consistent, accessible, and high quality at scale.

Design Systems sit at the intersection of design and engineering, creating the foundation that enables teams to build efficiently across products and experiences.

You’ll define the standard.

The Design Language System (DLS) is the foundation for American Express digital experiences. It provides the building blocks and standards teams use to design and develop products consistently at scale.

DLS enables teams to build fast, scalable, and accessible experiences through reusable primitives, standardized patterns, and robust tooling. With design tokens, theming, and accessibility built in, it ensures consistency while supporting flexibility across co-branded and sub-branded experiences.

Our goal is to abstract complexity so teams can focus on delivering high-quality user experiences.

Responsibilities

• Define and evolve the system architecture for the design system, ensuring scalability, performance, and long-term maintainability

• Design scalable, intuitive APIs for components and system layers

• Drive accessibility as a core requirement across all outputs

• Partner with designers to translate patterns into production-ready implementations

• Enable theming, surfaces, and responsive behavior across products

• Improve performance and runtime efficiency of shared components

• Create tooling, codemods, and automation to simplify adoption and upgrades

• Support engineers through documentation, training, and direct collaboration

• Review contributions to ensure quality, consistency, and backward compatibility

Qualifications

• Strong ability to solve complex system problems with simple, scalable solutions

• Experience building reusable UI systems, component libraries, or design systems

• Strong proficiency in JavaScript, React, and modern frontend architecture

• Deep understanding of CSS, layout systems, and responsive design

• Experience making system architecture decisions for design systems

• Strong attention to detail in UI consistency, motion, and interaction patterns

• Knowledge of accessibility standards and inclusive design practices

• Experience with design tokens, theming, or styling architectures

• Experience with build tooling and frontend infrastructure

• Experience working in monorepos and managing large-scale codebases

• Focus on improving developer experience through tooling, workflows, and automation

• Experience with testing strategies including unit, visual, and accessibility testing

• Strong communication skills to influence and educate across teams

• Ability to translate design and product requirements into scalable system solutions

• Understanding of performance optimization and frontend best practices

• Experience building or contributing to enterprise-scale design systems

• Familiarity with token pipelines or design-to-code workflows

• Experience with Figma or design tooling ecosystems

• Strong understanding of theming and scalable UI architecture

• Contributions to shared libraries or open-source projects
