Who we are

At OKX, we believe that the future will be reshaped by crypto, and ultimately contribute to every individual's freedom.

OKX is a leading crypto exchange, and the developer of OKX Wallet, giving millions access to crypto trading and decentralized crypto applications (dApps). OKX is also a trusted brand by hundreds of large institutions seeking access to crypto markets. We are safe and reliable, backed by our Proof of Reserves.

Across our multiple offices globally, we are united by our core principles: We Before Me, Do the Right Thing, and Get Things Done. 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 Role

We're looking for a Senior/Lead Algorithm Engineer to build our overseas growth algorithm capabilities from the ground up. You'll design and implement end-to-end ML systems that optimize paid advertising (Google, Meta), intelligent user targeting, and LTV prediction across 100+ countries and millions of users.

This is a high-impact role with significant ownership - you'll define the technical direction, build scalable systems, and directly influence how OKX acquires and retains high-value users globally. As the area matures, you'll have the opportunity to scale the team and grow into Staff Engineer or Engineering Manager roles.

What You'll Build

Design intelligent bidding algorithms for Google Ads, Meta Ads, and other paid channels to optimize CPA, ROAS, and user quality
Build automated budget allocation systems across campaigns, geos, and channels based on real-time performance and predicted LTV
Develop creative performance prediction models to guide A/B testing
Implement multi-touch attribution models to accurately measure channel contribution
