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.\nOur clients include Google, Microsoft, TikTok, DoorDash, Stripe, and Coinbase. Our research has been cited by Fortune, Forbes, TechCrunch, Adweek, and the Wall Street Journal.\nNewtonX has raised $47M from investors including Two Sigma Ventures, Third Prime, XFund, and Citi Ventures.\nAbout The Role\nWe 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.\nWhat We’re Looking For\n6+ years engineering experience, mostly frontend, including 3+ at a senior level owning projects end-to-end\n\nDeep React expertise - hooks, composition patterns, and the ability to reason about rendering behavior rather than guess at it\n\nStrong TypeScript - typing that catches real bugs instead of decorating the code\n\nExpert JavaScript (ES6+), HTML, and CSS/SCSS, including the modern layout model\n\nProven ownership of frontend architecture at scale: module boundaries, shared component libraries, and state management strategy\n\nWeb performance as a discipline - Core Web Vitals, bundle analysis, code splitting, virtualization, and profiling with real tooling\n\nAccessibility fluency - WCAG 2.1 AA, semantic HTML, keyboard and focus management, screen reader testing\n\nDesign system experience: reusable, themeable, documented components built in partnership with Design\n\nTesting depth - Jest and React Testing Library, plus end-to-end coverage (Playwright or Cypress) people actually trust\n\nFluency consuming APIs: REST and/or GraphQL, data-fetching and caching patterns (React Query, SWR, Apollo), and error states that hold up in production\n\nWorking knowledge of Python/Django - enough to read backend code, shape endpoints with backend engineers, and ship a small change yourself\n\nAbility to mentor, review code with judgment, and raise the bar without becoming a bottleneck\n\nBonus Skills (Nice-to-Haves)\nServer-side rendering (Next.js, Remix) and hydration tradeoffs\n\nFrontend observability and performance budgets enforced in CI (Sentry, Datadog RUM)\n\nData visualization at scale (D3, Recharts, Visx, canvas/WebGL)\n\nReal-time UI: WebSockets, polling strategies, streaming or collaborative interfaces\n\nStyling systems (Material-UI, Tailwind) and state management (Redux, Zustand)\n\nBuild and monorepo tooling ownership (Vite, Webpack, CI pipelines)\n\nCloud and infra exposure: GCP, Kubernetes, Docker, Terraform\n\nInternationalization, or SOLID design principles applied with judgment\n\nWhat You’ll Do\nOwn the architecture of our React/TypeScript applications and the patterns the team builds on\n\nLead development of performant, accessible UIs for complex research and analytics workflows\n\nSet and defend frontend standards - performance budgets, accessibility, testing, and quality gates in CI\n\nBuild and evolve our shared component library and design system with Design\n\nDrive measurable performance work: profile, fix the real bottleneck, instrument it so it stays fixed\n\nPartner with backend engineers on API contracts that make the frontend simpler, not harder\n\nPay down frontend technical debt deliberately, and contribute to Python/Django services where it speeds delivery\n\nMentor engineers and own department-wide technical initiatives from proposal through adoption\n\nWhat We Offer\nCompetitive 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.)\n\nExcellent medical, dental, and vision insurance.\n\n401k match with immediate vesting.\n\nGenerous Paid time off: vacation, holidays, sick, and parental leave.\n\nA diverse, collaborative, and positive culture where we invest in and celebrate each other’s success.\n\nNewtonX is proud to be an equal opportunity workplace. We do not discriminate based upon race, religion, color, national origin, sex, sexual orientation, gender identity/expression, age, status as a protected veteran, status as an individual with a disability, or any other applicable legally protected characteristics.","description_format":"text","description_chars":4628,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan","Equity","Parental leave","Vision insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Market Research"],"lifecycle":[{"event":"open","at":"2026-09-09T20:38:29Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 2 · green card filings: 1","filings_12m":2,"filings_prev_12m":5,"green_card_filings_12m":1,"median_offered_wage_usd":97500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":0}],"liveness":{"score":61,"band":"ok","label":"Likely open","p_open":1,"p_active":0.817,"p_room":0.75,"age_days":49,"expected_fill_days":59,"reasons":["conf:0","win:late"],"computed_at":"2026-10-29T05:49:05Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":true},"html_url":"https://alion.io/job/newtonx-staff-frontend-engineer","json_url":"https://alion.io/job/newtonx-staff-frontend-engineer.json","meta":{"generated_at":"2026-10-29T21:50:06Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":32314,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3688},"rest":"https://alion.io/mcp/rest/get_company?id=3688"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnewtonx-staff-frontend-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fnewtonx-staff-frontend-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fnewtonx-staff-frontend-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/newtonx-staff-frontend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnewtonx-staff-frontend-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":579505}},{"tool":"search_jobs","arguments":{"company":"newtonx.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":579505},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
