Java Backend Engineer – Web3 Data

Job Description

We are looking for a Senior Java Engineer (Web3 Data) to design and build the next-generation on-chain data processing and computation pipeline. You will play a key role in architecting high-performance, scalable, and reliable backend systems that parse, transform, and analyze blockchain data across multiple chains in real time.

This role requires a strong background in Java microservices, distributed systems, and data-intensive computation, with a solid understand for Web3 ecosystems and on-chain data analytics. You will work closely with blockchain researchers, data engineers, and backend teams to deliver low-latency APIs and large-scale data insights powering our DeFi and on-chain analytics products.

• Design and implement high-performance pipelines for on-chain data parsing, calculation, and aggregation across multiple blockchain networks (EVM, Solana, etc.).
• Architect and optimize Java-based distributed microservices for real-time and batch data processing.
• Build data computation layers that support ultra-fast statistical calculations, such as token prices, swaps, liquidity metrics, and protocol-level KPIs.
• Collaborate with data engineering teams to integrate pipelines with Kafka, Redis, RDS, and data lake environments.
• Design and manage scalable data models supporting multi-chain and historical data.
• Develop fault-tolerant, monitored, and auto-recoverable backend systems with zero downtime.
• Establish strong observability and performance monitoring for parsing and computation modules.
• Contribute to system-level architecture discussions and ensure alignment with long-term data platform strategy.

• 8+ years of experience in backend development with Java, including Spring Boot / Spring Cloud.
• Solid understanding of blockchain fundamentals —transactions, events, state changes, and node RPC interaction.
• Strong experience with distributed systems, streaming data, and real-time computation frameworks.
• Deep familiarity with commonly used middleware such as Kafka, Redis, MySQL,MongoDB,xxl-job and caching strategies for high-throughput workloads.
• Strong knowledge of microservice performance tuning and low-latency design (threading, async, batching).
• Excellent communication, documentation, and collaboration skills.
• Experience in Reactor would be an added value.

Why Binance

• Shape the future with the world’s leading blockchain ecosystem

• Collaborate with world-class talent in a user-centric global organization with a flat structure
