Get To Know The Team:

As a Senior Front-End Software Engineer, you’ll build user-facing features that are performant, accessible, and reliable. You will use React, TypeScript, and Next.js to deliver SSR/SSG/CSR solutions, contribute to our design system, and ship through modern CI/CD. Senior engineers will drive technical decisions and mentor peers.

Why You Will Love It Here!

• Flexibility: Hybrid Work Model & a Business Casual Dress Code, including jeans
• Your Future: 401(k) Matching Program, Professional Development Reimbursement
• Work/Life Balance: Flexible Personal/Vacation Time Off, Sick Leave, Paid Holidays
• Your Wellbeing: Medical, Dental, Vision, Employee Assistance Program, Parental Leave
• Wide Ranging Perspectives: Committed to Celebrating the Variety of Backgrounds, Talents, and Experiences of Our Employees
• Training: Hands-On, Team-Customized, including SS&C University
• Extra Perks: Discounts on fitness clubs, travel, and more!

What You Will Get To Do:

• Feature delivery: Implement end-to-end user stories in React/TypeScript with clean, testable code and responsive, accessible UI.

• Rendering strategy: Apply SSR/SSG/CSR appropriately (Next.js App Router, React Server Components/streaming) to balance SEO, performance, and complexity.

• Performance: Optimize for Core Web Vitals (LCP, INP, CLS); use code-splitting, lazy loading, caching, image optimization, and efficient state management.

• Design system: Build and maintain reusable components and tokens; document usage in Storybook; support theming and cross-app reuse.

• Quality & CI/CD: Add unit/e2e tests (Jest/Vitest, Playwright/Cypress), participate in reviews, and ship via automated pipelines (type checks, lint, a11y, visual regression).

• Accessibility (a11y): Ensure semantic HTML, ARIA, keyboard navigation, focus management, and contrast meet WCAG 2.2 AA.

• APIs & data: Collaborate with Backend on REST/GraphQL contracts; implement data-fetching patterns (React Query/TanStack, SWR) and error/empty states.

• Observability: Instrument telemetry (OpenTelemetry/console events), track client error rates and performance dashboards, and iterate based on data.

• (Senior) Tech leadership: Lead design docs/RFCs, make framework/library trade-offs, guide code reviews, and mentor junior/mid engineers.

What You Will Bring:

• 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).
   

Preferred Qualifications:

• Next.js (App Router), React Server Components, streaming, and incremental static regeneration.

• Experience with design systems (tokens, Storybook), visual regression testing, and component governance.

• Micro-frontends (Module Federation) or monorepo tooling (Nx/Turborepo).

• Internationalization (i18n) at scale.

• Observability (Sentry, OpenTelemetry, New Relic) and experimentation/analytics.

• Edge runtimes/CDN strategies (Vercel/Cloudflare), plus familiarity with WebAssembly/WebGL when applicable.

• Interest in applying AI/ML to improve UX or DX (e.g., content suggestions, automated testing).
