Elfa | Real-time intelligence stack for finance markets

Full-Stack Engineer (Frontend-Leaning)

Remote Apply

The Role

We're hiring a full-stack engineer who lives in the frontend. You'll work with the core product team to implement features end-to-end: design the UX, build the interface, wire up the backend, and ship it. Frontend is where we most need strength right now, so that's where you'll spend most of your time, but the best person here is comfortable dropping into the backend to land a feature without waiting on anyone. We work remotely on a GMT+8 timezone.

What You'll Do

• Build and polish our trading product: real-time charts, order flows, dashboards, and data-dense UI that has to feel fast and look great.

• Own features end-to-end, from UX/interaction design through frontend, API, and release.

• Contribute to and extend our design system (components, tokens, Storybook). Keep the product consistent and beautiful.

• Reach into backend services when a feature needs it: API endpoints, queries, queues.

• Work AI-first.

You will thrive if you have

• Strong sense of design & interactions & a deep obsession with pixels

• Good understanding of crypto primitives e.g (wallets, wagmi/viem, Privy).

• Appreciation for financial markets & trading

Stack

• React + TypeScript & Tailwind production experience with Next.js.

• Node/TypeScript backend experience: Express, REST APIs, Postgres (we use Kysely), Redis, queues (BullMQ/RabbitMQ).
