Senior UI Developer (ReactJS) – C2C requirements

Role: Senior UI Developer (ReactJS)(Looking for 10+ years of experience candidates only)

Location: Chicago, IL (Hybrid)(F2F interview in Client round must)(Only local)

Rate : $60/hr on C2C

 

Mandatory Skills:

React 18+, Angular 18+, TypeScript, JavaScript, HTML/CSS, Angular Material, React MUI, Design Systems, Design Tokens, Storybook, WCAG 2.1 AA, CI/CD, Azure DevOps, Git, Automated Testing (Jest/Karma/Cypress/Playwright), AI-assisted development tools (GitHub Copilot, Codex, Claude Code)

Desired Skills:

• Lit/Web Components, Shadow DOM, Micro Frontend Architecture, Nx Monorepo, Module Federation, npm Package Publishing, Azure Artifacts, GraphQL, Okta/OAuth2/OIDC, Visual Regression Testing, Healthcare Domain, HIPAA, SOC2

Job Description:

• In this role, you will build and maintain client's shared UI component libraries and the micro-product experiences that compose into the VIP platform shell.
• You will work with UX, Product Management, Platform Architecture, and QA teams. Together you will deliver a framework-agnostic web component toolkit alongside the existing Angular and React toolkits, and independently deployable micro-product UIs that mount into a shared shell.
• You will also help set the component standards, design token architecture, and automation that keep the toolkits in parity and let product teams move faster.

Responsibilities:

• Design, build, and maintain components across the Angular, React, and web component toolkits, keeping behaviour, accessibility, and styling in parity across all three.
• Build reusable UI components with Angular Material, React MUI, and Lit, working from Figma designs supplied by the UX team.
• Own and extend the shared design token layer that feeds every toolkit, and the theming that lets products adopt brand changes without rework.
• Build and extend micro-frontend applications using Nx monorepo tooling and Module Federation, including runtime composition of multiple frameworks on a single page.
• Design component APIs for consumption by other teams: props and inputs, composition patterns, and controlled versus uncontrolled behaviour.
• Own versioning, deprecation, and migration guidance for every breaking change.
• Publish and maintain npm packages to a private Azure Artifacts feed, with semantic versioning and release notes that consuming teams can act on.
• Integrate micro-product UIs with enterprise platforms, including Okta (OAuth2/OIDC, JWT bearer authentication) token flow across shell and products, and REST and GraphQL service layers.
• Keep quality high with automated testing: Jest and Karma for unit tests, Playwright or Cypress for end-to-end, and visual regression testing across every component on every deployment.
• Document components in Storybook across frameworks, and maintain the documentation site that designers and engineers both use.
• Build accessibility to WCAG 2.1 AA into every component — keyboard navigation, screen reader support, and focus management — so consuming products inherit it rather than solving it independently.
• Maintain CI/CD pipelines in Azure DevOps and GitHub Actions across dev, test, stage, and prod, with coverage and quality gates enforced.
• Take part in spec-driven development: turn design and product requirements into technical designs, ADRs, and implementation plans.
• Use AI-assisted engineering tools throughout.
• Mentor engineers, lead code reviews, and contribute to reference patterns, coding standards, and reusable components across the team.
• Evaluate new technologies and run proofs-of-concept to improve platform maturity and developer productivity.

Qualifications:

• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience).
• 5 or more years of professional front-end engineering experience.
• 3 or more years of hands-on experience with React (18+) and TypeScript.
• 3 or more years of hands-on experience with Angular (v18+), including standalone components, signals, and RxJS.
• Strong JavaScript fundamentals: DOM, the object model, and modern ECMAScript.
• Strong HTML and CSS: layout, responsive breakpoints, and cross-browser behaviour.
• Demonstrated experience building a shared component library or design system consumed by other teams.
• Hands-on experience with Angular Material and React MUI, including theming and style overrides.
• Experience with design tokens and multi-brand or multi-theme styling.
• Experience with Storybook for component documentation and development.
• Working knowledge of WCAG 2.1 AA accessibility and how to build to it.
• Experience writing automated unit, integration, and end-to-end tests.
• Experience building CI/CD pipelines and working in Git-based workflows.
• Daily working use of AI-assisted development tools such as Claude Code, GitHub Copilot, or Codex, including writing effective prompts and repo-level instruction files.
