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.
