Java Engineer — DeFi/ Web3

Binance

Job Description

Binance is a leading global blockchain ecosystem behind the world’s largest cryptocurrency exchange by trading volume and registered users. We are trusted by 300+ million people in 100+ countries for our industry-leading security, user fund transparency, trading engine speed, deep liquidity, and an unmatched portfolio of digital-asset products. Binance offerings range from trading and finance to education, research, payments, institutional services, Web3 features, and more. We leverage the power of digital assets and blockchain to build an inclusive financial ecosystem to advance the freedom of money and improve financial access for people around the world. Responsibilities:

Design, develop, and maintain high-performance systems, ensuring architectural rationality and system reliability.

Participate in the research, design, and development of De Fi Adapter contracts, integrating with mainstream De Fi protocols (Lending, DEX, Staking, Yield, etc.) to deliver standardized on-chain asset and position parsing.

Deeply understand blockchain technology and De Fi protocol mechanics; independently conduct on-chain contract analysis and transaction deconstruction.

Leverage AI-powered development tools (e.g., Copilot, Cursor, Code Max) to accelerate coding, code review, and smart contract analysis workflows, continuously improving development efficiency and code quality.

Explore and apply AI capabilities — such as LLM-based code generation, on-chain data interpretation, and automated protocol research — to streamline team workflows and reduce repetitive effort.

Collaborate effectively within the team, actively contribute to technical architecture and solution design, and stay current with emerging technologies.

Drive the adoption of innovative technologies and solutions within the team, approaching problem- solving with a forward-thinking mindset.

Requirements:

Approximately 5 years of Java development experience with a solid foundation in computer science.

Proficient in multi-threaded programming; familiar with JVM internals and common open-source distributed middleware, caching, and message queues; skilled in My SQL performance tuning.

Familiar with frameworks such as Spring Cloud; experience in designing and ensuring stability of large- scale distributed, high-concurrency, and high-availability systems is a plus.

Familiar with Solidity smart contract development; understanding of EVM execution mechanics and common contract design patterns (Proxy, Factory, etc.); hands-on contract development or auditing experience is a plus.

Capable of on-chain data analysis — able to trace transactions, decode contract call chains via block explorers or RPC calls.

Understanding of mainstream De Fi protocol mechanics (e.g., Aave, Uniswap, Curve, Pancake Swap), including Lending, AMM, and Staking models. Multi-chain development experience is a plus (Ethereum, BSC, Arbitrum, etc.), with awareness of cross- chain differences and compatibility considerations.

Proficient in using AI-assisted development tools in daily workflows; experience with prompt engineering, AI-driven code generation, or integrating LLM-based solutions into development pipelines is highly desirable.

Open to AI-augmented approaches for smart contract analysis, protocol research, and test case generation; demonstrated ability to identify and apply AI solutions to improve engineering efficiency.

Passionate about technology with high standards for code quality and development practices; strong team communication and collaboration skills.

Strong logical thinking, excellent problem analysis and resolution abilities, with a high sense of responsibility.
