About the Opportunity

The work of the blockchain parsing team involves structuring on-chain data. This means taking all the raw data from the blockchain and, through business modeling, computation, transformation, and other operations, converting it into the data required by various business applications (such as wallets, explorers, CeFi, etc.). This process involves parsing on-chain data from hundreds of blockchains with different architectures, including EVM, UTXO, Cosmos, Move, and more, as well as scheduling these operations. It also encompasses the management of complete historical data for each blockchain, reaching the scale of petabytes (PB) of data.

• Responsible for researching various blockchain architectures and on-chain data parsing.
• Maintain good communication with the team, provide rational suggestions for requirements, and ensure the development work progresses smoothly as planned; ensure the system meets performance, scalability, and security requirements.
• Responsible for database design, system design, API interface design, and external system integration.
• Troubleshoot and resolve issues across the entire pipeline; optimize and improve the availability and capacity of online services, and handle unexpected online issues.

Selling point of the team

• Gain exposure to the latest public blockchain technologies in the industry.
• Work with and manage the largest volume of on-chain data in the industry, which involves hundreds of blockchains.
• Our team is a core part of the company's infrastructure. You'll gain insight into how complex foundational services are built to support multiple business lines, including wallets, DeFi, CeFi, explorers, and tracking tools. Our approach is innovative and leading in the industry.

What We Look For In You

• Solid foundation in Java, with extensive experience in Java multithreading, concurrency, and network communication, and good coding practices.
• Familiar with common open-source projects or middleware (at least one or two), with source code experience being a plus, such as Kafka, RocketMQ, GRPC, Dubbo, Redis, MySQL, Elasticsearch (ES), caching mechanisms, Spring/SpringBoot, etc.
• Proficient in mainstream open-source application frameworks such as SpringBoot, SpringMVC, MyBatis, SpringCloud, etc.
• Experience in developing and designing large-scale data platforms.
• Strong learning ability, teamwork, and communication skills; proactive in thinking and capable of independent analysis and problem-solving.
