SS&C is looking to build user-facing features that are performant, accessible, and reliable using React, TypeScript, and Next.js.

Requirements

  • Mid-level: 3–5 years building production web apps with React, TypeScript/JavaScript, HTML, and CSS.
  • Senior: 5–8+ years, including leading feature delivery across services/teams and mentoring peers.
  • Strong grasp of web performance (network, rendering, hydration), state management (React Query/Redux/Zustand/Signals), and API consumption (REST/GraphQL).
  • Hands-on with testing (Jest/Vitest, Playwright/Cypress) and CI/CD.
  • Practical accessibility skills (semantic HTML, ARIA, screen readers, focus, contrast).
  • Next.js (App Router), React Server Components, streaming, and incremental static regeneration.
  • Experience with design systems (tokens, Storybook), visual regression testing, and component governance.

Responsibilities

  • Implement end-to-end user stories in React/TypeScript with clean, testable code and responsive, accessible UI.
  • Apply SSR/SSG/CSR appropriately (Next.js App Router, React Server Components/streaming) to balance SEO, performance, and complexity.
  • Optimize for Core Web Vitals (LCP, INP, CLS); use code-splitting, lazy loading, caching, image optimization, and efficient state management.
  • Build and maintain reusable components and tokens; document usage in Storybook; support theming and cross-app reuse.
  • Add unit/e2e tests (Jest/Vitest, Playwright/Cypress), participate in reviews, and ship via automated pipelines (type checks, lint, a11y, visual regression).
  • Ensure semantic HTML, ARIA, keyboard navigation, focus management, and contrast meet WCAG 2.2 AA.
  • Collaborate with Backend on REST/GraphQL contracts; implement data-fetching patterns (React Query/TanStack, SWR) and error/empty states.
