Sr Software Engineer, Front End

About the role

The Fiat team at OKX is responsible for building the money experiences of OKX. This includes fiat deposits, withdrawals, and payment methods across 100+ markets, as well as Simple Buy/Sell for onshore and offshore markets, and Cards & Pay, which takes OKX into the money app category.

Responsibilities

• Own and ship the money experiences of OKX — fiat deposit/withdraw, Simple Buy/Sell for onshore and offshore markets, and Cards & Pay — the surfaces used by millions of users.
• Build AI-native engineering infrastructure: agent harnesses, reusable skills, E2E automation, and evaluation pipelines that multiply the whole team's output.
• Make the product data-driven: instrument what you ship, build the tracking and experimentation foundations yourself when they don't exist, and let the numbers decide.
• Drive frontend quality end-to-end — architecture, performance, testing, and server-driven UI systems that stay backward-compatible in production.
• Work directly with product, design, and backend teams across the US and APAC to turn ambiguous requirements into shipped features.
• Contribute tooling, patterns, and practices beyond your own team — what you build should raise the bar for the wider engineering group.

Requirements

We look for a front-end engineer who is sharp, curious, data-driven, and believes most "impossible" things simply haven't been automated yet. Strong computer science fundamentals and frontend essentials are required, including TypeScript, React, modern toolchains (Vite), browser internals, and state management. Depth beyond framework APIs, a good sense of web performance, responsive design, and web security are also important. Hands-on creativity with AI-assisted development, sharp problem-solving, self-driven and resilient nature, and a conviction that decisions should be data-driven are essential qualities.

Qualifications

• A BS/MS in Computer Science or a related field from a strong program, or equivalent evidence of exceptional ability.
• Proficiency in Mandarin Chinese is required to communicate effectively with our engineering and product teams across APAC.
