Full job description
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 a Senior Staff Mobile Engineer to join our Mobile Infrastructure team, the foundational engineering group that powers the OKX app for millions of daily active users. This is not a feature delivery role. You will work at the platform layer, building the tools, frameworks, and systems that enable product engineering teams to move faster, ship higher quality code, and scale reliably.
You are deeply native in either iOS or Android, and confident contributing across both platforms leveraging AI coding tools to move fluidly between stacks. You care about engineering quality at the foundation level: architecture, performance, toolchain, and developer experience.
What You'll Be Doing
Build and maintain mobile infrastructure, tooling, and shared frameworks that improve engineering efficiency and developer experience across the organisation.
Analyse and optimise application code at the UI and infrastructure layer, including memory footprint, package size, startup time, and rendering performance.
Design and develop reusable, scalable mobile components for use across iOS and Android platforms.
Partner with product engineering teams to deliver infrastructure solutions, establish best practices, and drive technical standards.
Drive architecture innovations that support world-class mobile app development at scale.
Optimise project structure and engineering workflows to improve productivity, quality, and release velocity.
Apply AI coding tools to accelerate infrastructure development, improve code quality, and cross-translate solutions across iOS and Android platforms.
Stay current with mobile platform developments and emerging toolchain innovations, evaluating and adopting what moves the needle.
What We Look For In You
6+ years of native iOS or Android development experience, with a strong track record in infrastructure, platform, or architecture work.
Deep expertise in either iOS (Swift/Objective-C/C++) or Android (Kotlin/Java, Jetpack), with confidence contributing across both platforms.
Actively uses AI tools in your engineering workflow — including building AI-leveraged workflows, curating domain knowledge bases, and codifying repeatable agent skills so tools like Claude Code or Codex deliver reliably on real production work.
Proven experience optimising app performance — memory, package size, startup time, and UI rendering — in production environments at scale.
Deep understanding of design patterns, architectural principles, and the mobile SDK layer for building scalable, high-performance components.
Working knowledge of remote APIs, concurrency, layouts, transitions, animations, client-side persistence, and mobile architectural patterns.
Strong communication skills — comfortable collaborating across global teams and delivering large-scale engineering outcomes independently.
Nice-To-Haves
Experience working in a dedicated mobile architecture or infrastructure team with deep platform specialisation.
Hands-on experience across performance optimisation, toolchain engineering, automated testing frameworks, or design pattern standardisation.
Experience working across both iOS and Android in a production infrastructure context.
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
Wellness and meal allowances
Comprehensive healthcare schemes for employees and dependants
More that we love to tell you along the process!
