Front-End Developer Remote

Front-End Developer (Full-Time, Remote)

We are seeking a Front-End Developer to design and build the user-facing components of our high-performance trading platform. You will play a key role in creating intuitive, data-rich interfaces that enable traders and analysts to work efficiently and effectively.

You will collaborate closely with the Back-End Development Team and the Project Manager to deliver seamless, integrated systems. A key factor is the front end developer’s ability to deeply discuss approaches, trade-offs, limitations, and pros/cons with the development team, rather than reliance on any specific pattern or library.

Key Responsibilities

* Develop and maintain the front-end applications of our trading platform.

* Collaborate with back-end developers and the project manager to ensure smooth integration across systems.

* Design and implement multi-page layouts, menus, and workflows that balance usability with efficiency.

* Contribute to the design and user experience of the trading platform, performance & risk manager, and backtesting engine.

* Implement and optimize charting and data visualization features, leveraging libraries such as Trading View or D3.js to support a wide variety of chart types (tables, multi-line chart packs, etc.).

* Continuously refine the UI/UX to ensure clarity, speed, and intuitive navigation for end users.

Qualifications

* Strong communication skills and the ability to collaborate effectively with developers, project managers, and business stakeholders.

* A keen eye for design, simplicity, and efficiency, with the ability to translate complex requirements into clean, user-friendly interfaces.

* Knowledge of financial systems or trading concepts is preferred.

Core stack (mandatory)

* React 18 + Next.js (App Router), Type Script, Tailwind

CSS.

* Strong command of state management for high-frequency data (e.g., Zustand, Redux Toolkit, useSync External Store ).

Real-time data & performance

* Hands-on with Web Sockets / SSE and reconnection/backoff strategies; handling authenticated socket connections and topic resubscriptions.

* Experience implementing back pressure, buffering, coalescing, and windowing to prevent UI thrash under thousands of updates/minute.

* Data virtualization (react-virtualized, react-window) for large tables (orders, positions, trades).

* Familiar with Web Workers / Offscreen Canvas and message passing to keep the main thread responsive.

* Awareness of latency budgets and frame-time profiling using React Dev Tools and browser performance tools.

Charting & visualization

* Practical experience with professional charting libs (e.g., Trading View Charting Library, Lightweight Charts, Highcharts, D3).

* Real-time overlays: best bid/ask, order book depth, last OHLCV, order/position annotations.

* Multi-pane layouts (price, volume, indicators) with synchronized crosshairs and time scales.

Architecture & data access

* Client-side caching and invalidation (e.g., Tan Stack Query / React Query).

* Schema-driven UI for instruments and venues.

* Use of Error Boundaries, Suspense, and progressive hydration/streaming for large Next.js pages.

Auth, security, and roles

* Strong understanding of OIDC/JWT flows, token refresh/rotation, and Web Socket authentication.

* Role-based feature gating (read-only vs trading permissio

Testing, quality, and reliability

* Unit tests for critical transforms/parsers (e.g., Playwright/Vitest for E2E/interaction flows)

* Experience with feature flags, staged rollouts, and monitoring with Sentry/Open Telemetry.

Nice-to-haves

* Experience with desktop-class layouts (drag-to-dock panels, resizable grids).

* Exposure to WASM for heavy computations (e.g., indicator calculations).

* Familiarity with FIX/crypto venue nuances (tick sizes, lot sizes, trading sessions).
