Note: The job is a remote job and is open to candidates in USA. NewtonX is a B2B insights company that combines a verified professional network with AI-powered research tools to deliver research intelligence. The Staff Frontend Engineer will own the architecture of React and TypeScript applications, lead the development of performant and accessible interfaces for research and analytics workflows, and establish frontend standards. The role also involves building design systems, improving performance, partnering on API contracts, contributing to Python/Django services, and mentoring engineers.
Responsibilities
- Own the architecture of our React/TypeScript applications and the patterns the team builds on
- Lead development of performant, accessible UIs for complex research and analytics workflows
- Set and defend frontend standards — performance budgets, accessibility, testing, and quality gates in CI
- Build and evolve our shared component library and design system with Design
- Drive measurable performance work: profile, fix the real bottleneck, instrument it so it stays fixed
- Partner with backend engineers on API contracts that make the frontend simpler, not harder
- Pay down frontend technical debt deliberately, and contribute to Python/Django services where it speeds delivery
- Mentor engineers and own department-wide technical initiatives from proposal through adoption
Skills
- • 6+ years engineering experience, mostly frontend, including 3+ at a senior level owning projects end-to-end
- • Deep React expertise — hooks, composition patterns, and the ability to reason about rendering behavior rather than guess at it
- • Strong TypeScript — typing that catches real bugs instead of decorating the code
- • Expert JavaScript (ES6+), HTML, and CSS/SCSS, including the modern layout model
- • Proven ownership of frontend architecture at scale: module boundaries, shared component libraries, and state management strategy
- • Web performance as a discipline — Core Web Vitals, bundle analysis, code splitting, virtualization, and profiling with real tooling
- • Accessibility fluency — WCAG 2.1 AA, semantic HTML, keyboard and focus management, screen reader testing
- • Design system experience: reusable, themeable, documented components built in partnership with Design
- • Testing depth — Jest and React Testing Library, plus end-to-end coverage (Playwright or Cypress) people actually trust
- • Fluency consuming APIs: REST and/or GraphQL, data-fetching and caching patterns (React Query, SWR, Apollo), and error states that hold up in production
- • Working knowledge of Python/Django — enough to read backend code, shape endpoints with backend engineers, and ship a small change yourself
- • Ability to mentor, review code with judgment, and raise the bar without becoming a bottleneck
- • Server-side rendering (Next.js, Remix) and hydration tradeoffs
- • Frontend observability and performance budgets enforced in CI (Sentry, Datadog RUM)
- • Data visualization at scale (D3, Recharts, Visx, canvas/WebGL)
- • Real-time UI: WebSockets, polling strategies, streaming or collaborative interfaces
- • Styling systems (Material-UI, Tailwind) and state management (Redux, Zustand)
- • Build and monorepo tooling ownership (Vite, Webpack, CI pipelines)
- • Cloud and infra exposure: GCP, Kubernetes, Docker, Terraform
- • Internationalization, or SOLID design principles applied with judgment
Benefits
- Equity
- Excellent medical, dental, and vision insurance.
- 401k match with immediate vesting.
- Generous paid time off: vacation, holidays, sick, and parental leave.
- A diverse, collaborative, and positive culture where we invest in and celebrate each other’s success.
