Senior Frontend Engineer

Responsibilities:

• Ship across the core platform and core products: the real-time trading terminal, charting, and the product features on the roadmap, owning them from idea to production.
• Work on the SDK, the charting/platform SDK that powers our own product and partner/white-label use, including its developer-facing surface and contracts.
• Build for performance and real-time data-dense, canvas/visualization-heavy, WebSocket-driven UIs that stay fast under live market data.
• Operate full-stack when needed; reach into the Go backend and the REST/WebSocket APIs to land a feature end-to-end rather than stopping at the frontend boundary.
• Move across our codebases: the established terminal (React) and the newer product monorepo (modern React + SSR, internationalised), bringing consistency and quality with you.
• Be a senior multiplier, make sharp technical calls with little hand-holding, raise the bar on the frontend, and unblock the CEO's product ambitions.

Requirements:

• 7-10 years of frontend engineering, with very senior React depth; you've owned large, complex, stateful applications and you know how to keep them fast and maintainable.
• Strong TypeScript and modern frontend architecture.
• Full-stack capable, comfortable in a backend (we run Go) and working directly with REST and WebSocket.
• APIs; you don't stop at the UI boundary.
• Plugged into financial services/trading; you understand the domain (charts, market data, order flow, the trader's workflow) and can hit the ground running, not ramp for a quarter.
• Performance and real-time chops; experience with data-dense, real-time, or visualisation-heavy UIs (canvas/D3/WebGL a strong plus).
• High autonomy: you can own an ambiguous product/SDK surface and drive it without a fully-specced ticket.
