We combine a verified network of business professionals with AI-powered research tools to deliver research intelligence faster, more precise, and more defensible than traditional methods. Our clients include Google, Microsoft, TikTok, DoorDash, Stripe, and Coinbase. Our research has been cited by Fortune, Forbes, TechCrunch, Adweek, and the Wall Street Journal. NewtonX has raised $47M from investors including Two Sigma Ventures, Third Prime, XFund, and Citi Ventures. ## About The Role We are looking for a Staff Frontend Engineer with deep expertise in React and TypeScript. You’ll own the frontend architecture behind the data-dense applications our clients and research teams use every day, where performance, accessibility, and interaction quality are the product. This is a hands-on role: you’ll write production code, but your leverage comes from the systems and standards you leave behind. ## What We’re Looking For - 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 Bonus Skills (Nice-to-Haves) - 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 ## What You’ll Do - 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 ## What We Offer - Competitive compensation with a total compensation range of $180k-$240k and equity. (Please note that salary and compensation may vary based on skills, experience, performance, and location.) - 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. NewtonX is proud to be an equal opportunity workplace.
