These shared values drive our culture, shape our processes, and foster a friendly, rewarding, and diverse environment for every OK-er. OKX is part of OKG, a group that brings the value of Blockchain to users around the world, through our leading products OKX, OKX Wallet, OKLink and more.

About the Opportunity

The Fiat team builds the money experiences of OKX. Beyond the payment rails — fiat deposits, withdrawals, and payment methods across 100+ markets — we own Simple Buy/Sell, the front door to crypto for both onshore and offshore markets, and Cards & Pay, the products taking OKX into the money app category and giving customers a whole new reason to connect with us. We sit inside the Bay Area AI-Native Product & Engineering Center: we don't just use AI tools, we build agent harnesses, evaluation pipelines, and automation that lets a small team ship like a large one. We're looking for a front-end engineer who is sharp, curious, data-driven, and believes most "impossible" things simply haven't been automated yet.

What You’ll Be Doing

• 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.
