React Developer

React Developer — Portal React (Trading Platform) Summary We're looking for a React developer to contribute to our trading portal frontend. Strong TypeScript and modern React fundamentals matter more than deep fintech experience. Junior/mid-level React/TypeScript developer (React 19, Vite, Storybook, Vitest) for a layered trading-portal UI — strong component architecture discipline and comfort with data tables/charts required; fintech background optional. Details Required experience React 19 — functional components and hooks only (no class components) TypeScript — comfortable in a typed codebase; no any React Router v7, Vite, and CSS Modules State management: React Context + useReducer, plus Valtio for shared stores Testing: Vitest, React Testing Library, Storybook (CSF3) ESLint — comfortable following enforced architectural rules, not fighting the linter Git — standard workflow; awareness that some shared code lives in a read-only submodule UI libraries (regular use) MUI v7 + Emotion AG Grid and/or TanStack Table Recharts or lightweight-charts Toast/notification libraries (e.g. notistack, react-toastify) Architecture (important) We use a layered component architecture (pages → widgets → stateful containers → pure components). Candidates should be comfortable with: Container/presentational split — logic in stateful containers, UI in pure components Props-driven pure components — no hooks or side effects in presentational code Storybook-first — new UI work includes stories Nice to have Docker, Nginx, Playwright, i18next, real-time data (WebSockets/SignalR), trading/financial UI, or chart-heavy dashboards. Mindset Follow existing patterns; keep changes focused Take ownership of what you ship Trading-domain knowledge is a plus, not a requirement Financial services experience is a plus but not required.
