• Collaborate with Product, UX, and Backend teams to define and implement user-centric features, including API contracts and edge-case handling

• Build reusable UI components and contribute to a consistent design system (component libraries, styling conventions, documentation)

• Ensure code quality through best practices: clear PRs, code reviews, automated testing, and developer-friendly documentation

• Optimize applications for speed and reliability (Core Web Vitals, bundle size, rendering performance) and ensure responsive behavior across devices

• Ship accessible experiences by incorporating WCAG-aligned practices into component design, interaction patterns, and QA workflows

• Participate in architecture discussions and help define front-end development standards (state management, data fetching, routing, error handling)

• Maintain build pipelines, including configuring tools like Vite, managing dependency upgrades, and troubleshooting CI/CD issues

• Mentor and support other engineers through pairing, technical guidance, and sharing practical patterns that improve team velocity

You Have:

• A Bachelor’s or Master’s degree in Computer Science/Engineering or equivalent practical experience

• 10+ years of front-end development experience building production web applications and SDKs with modern JavaScript frameworks (React)

• Strong proficiency in HTML5, CSS3, and JavaScript, plus responsive design principles

• Experience with state management and scalable front-end architecture patterns (e.g., Redux / Redux Toolkit)

• Hands-on experience integrating RESTful APIs and collaborating closely with backend teams (error states, pagination, auth, caching considerations)

• Solid testing and quality practices (e.g., Jest/Vitest, React Testing Library, Enzyme and end-to-end testing with Playwright or Cypress)

• Familiarity with source control and CI/CD workflows (e.g., GitHub/GitLab, automated builds, linting, test pipelines, release processes)

Bonus Points If You Have:

• Knowledge of Decentralized Identity (DCI) and Identity & Access Management (IAM) concepts, including auth patterns like OAuth/OIDC

• Experience working alongside platform teams using technologies like Kubernetes, Cassandra, Kafka, and Redis (and understanding how they influence UI/API design)

• Familiarity with accessibility standards (WCAG) and internationalization (i18n) tooling and workflows (e.g., i18next, formatjs/react-intl)

• Experience with performance monitoring and feature-flagging tools such as New Relic and Launch Darkly (plus tools like Sentry, Datadog RUM, or Open Telemetry)

• Experience with modern React ecosystems and build tooling (e.g., React 18+, Next.js/Remix, Vite, code-splitting, SSR/ISR where relevant)
