In the rapidly evolving world of cryptocurrency and decentralized technology, mobile platforms are at the forefront of user interaction. As a Senior/Staff Android Developer at OKX, you’ll play a pivotal role in shaping the future of digital finance through one of the most widely used crypto applications in the world. With millions of daily active users relying on the OKX app for trading, asset management, and wallet functionality, your work will directly impact how individuals and institutions access and interact with blockchain technology.
OKX is more than just a leading crypto exchange — it's a comprehensive ecosystem empowering users globally. From the OKX Wallet to dApp integration and institutional-grade trading tools, the platform is built on innovation, security, and scalability. At the heart of this ecosystem is a dedicated global engineering team committed to delivering seamless, high-performance mobile experiences.
Building the Future of Crypto on Mobile
As a key member of the mobile engineering team, you'll be responsible for developing and maintaining core features of the all-in-one OKX Android application. This isn’t just another finance app — it’s a powerful gateway to decentralized finance (DeFi), spot and derivatives trading, NFTs, Web3 services, and self-custody wallets. Your contributions will help shape how users engage with crypto across regions, languages, and regulatory environments.
You’ll collaborate closely with product managers, UX designers, backend engineers, and international teams to translate complex financial workflows into intuitive, responsive, and secure mobile experiences. Whether optimizing trade execution speed or enhancing wallet onboarding flows, every line of code you write has real-world impact.

Key Responsibilities
- Develop and ship new features for the Android app using native technologies (Kotlin/Java) or cross-platform frameworks such as React Native or Flutter.
- Optimize performance and stability, ensuring smooth user experiences even under high-load conditions like market volatility or major token launches.
- Collaborate across disciplines, working hand-in-hand with design and product teams to turn conceptual ideas into scalable, production-ready features.
- Maintain architectural consistency while delivering localized solutions tailored to diverse global markets.
- Stay ahead of industry trends, evaluating emerging tools, libraries, and development practices to meet the fast-paced demands of the crypto space.
- Document technical processes clearly and effectively to support collaboration across time zones and distributed teams.
Who You Are
We're looking for experienced Android developers who are passionate about building robust, user-centric applications at scale. You should have a deep understanding of mobile development principles and a proven track record of delivering high-quality software in agile environments.
Core Requirements
- Proven experience in native Android development (Kotlin or Java) or cross-platform frameworks such as React Native, Flutter, or Lua.
- Strong command of at least one programming language: Kotlin, Java, or JavaScript.
- Solid foundation in data structures, algorithms, and software design patterns.
- Familiarity with modern development methodologies including Test-Driven Development (TDD), Continuous Integration (CI), and Scrum.
- A passion for mobile technology and building applications that serve millions of users with reliability and speed.
Why This Role Stands Out
Unlike traditional fintech roles, this position offers exposure to the full lifecycle of crypto-native mobile applications — from wallet integration and private key management to real-time trading engines and blockchain explorers. You’ll gain hands-on experience with cutting-edge technologies in Web3, decentralized identity, smart contracts, and secure key storage — all within a product used by both retail investors and major financial institutions.
