As a Staff Software Engineer in Rust (Cross-Platform), you will shape OKX's next-generation cross-platform architecture. You'll design and build core services and frameworks that power OKX products across multiple platforms, driving engineering excellence in one of the fastest-moving industries.

• Lead design and development of cross-platform software components in Rust, ensuring performance, safety, and reliability.
• Architect scalable, maintainable systems deployable across diverse operating systems and hardware architectures.
• Define and enforce coding standards, testing frameworks, and CI/CD practices for code quality and development efficiency.
• Build and maintain shared components and libraries to streamline development across OKX's applications and platforms.
• Solve complex interoperability challenges involving FFI bindings, system integration, and platform-specific optimizations.
• Mentor engineers across teams on Rust best practices, system design, and architectural principles.
• Shape OKX's technology strategy and engineering culture through cross-functional collaboration and technical leadership.
• Bachelor's degree in Computer Science, Software Engineering, or related field.
• 6+ years of production software development experience, with 3+ years specializing in Rust.
• Expert-level proficiency in Rust: ownership/borrowing, lifetimes, async programming, unsafe Rust, and FFI integration.
• Solid understanding of Rust compiler internals, WebAssembly (WASM), and modern build toolchains.
• Deep knowledge of systems programming: concurrency models, memory management, CPU architecture, and performance profiling.
• Strong foundation in data structures, algorithms, and operating system fundamentals.
• Excellent communication and leadership skills with proven experience mentoring engineers and delivering complex systems at scale.
• Active contributions to the Rust open-source community or notable public projects.
• Experience with blockchain systems, smart contracts, or cryptographic protocols.
• Background in high-performance or embedded systems development.
• Prior experience in trading systems or financial technology platforms.
