Senior Front-End Engineer
About Virtasant Virtasant is a global technology services company with a network of over 4,000 technology professionals across 130+ countries. We specialize in cloud architecture, infrastructure, migration, and optimization, helping enterprises scale efficiently while maintaining cost control. Our clients range from Fortune 500 companies to fast-growing startups, relying on us to build high-performance infrastructure, optimize cloud environments, and enable continuous delivery at scale. About the role Join us to own major product features end-to-end in a modern, well-architected monorepo, no legacy rescue work here. You’ll ship polished experiences across web and mobile using React 19 + TypeScript 5.9, React Router 7 (SSR), Vite, and a shared design system. If you care about craft, autonomy, and AI-augmented speed, you’ll fit right in. What You’ll Do ● Lead complex product work such as payment flows with Stripe, robust form validation, real-world edge cases,and ship with tests and monitoring. ● Build cross-platform features that share logic across React (web) and React Native 0.81/Expo 54 (iOS/Android) using our custom shared packages, with Cloudflare Workers powering SSR for fast first paint. ● Evolve our design system (100+ components) with accessible, composable primitives built with Tailwind CSS; contribute extensible component patterns, design tokens, and comprehensive docs; ensure WCAG AA+ and great keyboard/screen-reader support. ● Deliver data-heavy interfaces using TanStack Query and React Table (virtualization, sorting, filtering, optimistic updates), while keeping performance and UX crisp. ● Partner with design and product to clarify requirements, surface risks, propose alternatives, and plan incremental rollouts; measure outcomes via Sentry and FullStory. What We’re Looking For Must-Have Experience ● 8+ years building production applications for thousands+ users; 4+ years deep React expertise (hooks-era and beyond); 6+ years JS/TS. ● Proven in large-scale products: real CI/CD, code review, observability, incident response, and long-term maintenance,not just prototypes or internal tools. ● 3+ years implementing high-fidelity designs from Figma/Adobe XD in a product environment: pixel/snapping discipline, responsive intent, motion/micro-interactions, and typography craft. ● Experience in React Native (2+ years strongly preferred) shipping to both iOS and Android with Expo; comfortable sharing code across platforms. ● Fluency with our stack’s patterns: pnpm + Turbo monorepo, Vite, React Router 7 SSR, TanStack Query, Formik, Storybook, Vitest/Playwright, and visual regression testing. ● Strong systems thinking for design systems: tokens, theming, accessibility, composable APIs (Ariakit-based components), and avoiding one-offs. ● AI-augmented workflow: you regularly use tools like Claude/Copilot/Cursor for research, scaffolding, tests, and refactors,and you critically review every line. ● Clear communicator: writes concise docs, reviews PRs thoughtfully, and explains trade-offs to technical and non-technical partners. Why This Role is Exciting ● Modern foundation, not a cleanup job: a 2025-grade React/TypeScript monorepo with conventions, tests, and a mature component library so you spend time building,not untangling debt. ● Real ownership: take a Figma spec to production, shape the architecture, call out risks, and drive incremental launches backed by metrics. ● AI-forward culture: we expect AI to accelerate craft, not replace it,use it for speed, keep judgment and quality as the bar. ● End-to-end impact: from API contracts and state strategy to polish, accessibility, and performance.
