OKX will be prioritising applicants who have a current right to work in Hong Kong, and do not require OKX's sponsorship of a visa.

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 Opportunity

We are looking for an experienced engineering leader to join our Mobile Infrastructure team and drive the technical foundation that powers OKX's app for millions of daily active users. In this role, you will lead and grow a team of mobile infrastructure engineers, set the technical direction for our platform layer, and work closely with product engineering teams to ensure the OKX app is fast, reliable, and built to scale.

This is not a feature delivery role. You will own the engineering systems, tooling, and frameworks that enable the broader mobile organisation to ship with speed and confidence. We are actively embedding AI into how our teams build and operate — and we're looking for a leader who embraces that shift and brings others along with them.

What You'll Be Doing

Lead, mentor, and develop a mobile infrastructure engineering team, driving ownership and accountability across platform milestones.
Set the technical direction for mobile infrastructure — including tooling, shared frameworks, performance systems, and developer experience toolchain.
Champion the adoption of AI tools and workflows across the team — from code generation and review to testing and incident analysis — to raise the quality and velocity of delivery.
Drive architecture decisions and engineering standards across the mobile platform, ensuring scalability, reliability, and maintainability at scale.
Partner with product engineering teams to deliver infrastructure solutions, unblock development, and raise the bar on engineering quality across the organisation.
Own performance engineering across the platform — memory, package size, startup time, and UI rendering — in production environments serving millions of users.
Collaborate with cross-functional stakeholders including product, design, backend, and security teams to align on platform goals and execute effectively.
Serve as the go-to technical expert for complex infrastructure challenges, maintaining the robustness and scalability of the mobile platform.

What We Look For In You

8+ years of mobile engineering experience, with at least 3 years in a team lead or management role focused on infrastructure, platform, or architecture.
Proven ability to lead and grow engineering teams, with strong technical judgement and a high level of drive.
Deep expertise in iOS or Android development, with a strong understanding of the mobile platform layer — performance, toolchain, architecture, and developer experience.
Actively uses AI tools in your engineering workflow — you don't just know about them, you've integrated them into how you and your team work.
Strong communicator who can align cross-functional teams and work effectively across stakeholders at different levels.
Comfortable navigating ambiguity and making sound technical decisions in a fast-paced environment.

Nice to Haves

Hands-on experience leading a dedicated mobile architecture or infrastructure team with deep platform specialisation.
Track record of driving performance optimisation at scale — memory, package size, startup time, and rendering performance.
Experience shipping AI-powered features or integrating AI tooling into engineering workflows at team or org level.
Familiarity with cross-platform frameworks such as React Native or Flutter.
Experience in fintech, crypto, or other high-scale consumer app environments.

Perks & Benefits

Competitive total compensation package
L&D programs and Education subsidy for employees' growth and development
Various team building programs and company events
