资深Web3研发工程师 — 交易询价方向

This is a fully remote position, open to applicants in China.

📋 Description

• Responsible for the backend architecture design and development of a Web3 aggregated trading system, integrating multiple public chains, various DEXs, and liquidity sources from market makers.

• Design and implement routing algorithms and optimal path selection strategies, balancing multiple objectives such as price, slippage, gas, and transaction probability.

• Oversee the complete transaction process including construction, signing, broadcasting, and status tracking, ensuring stability and success rates in high concurrency and network congestion scenarios.

• Develop and implement a Request for Quote (RFQ) system, interfacing with on-chain liquidity pools, off-chain market makers, and centralized exchanges (CEX) for various quote sources.

• Create and implement a market maker access protocol, covering quote subscription, updates, transaction confirmations, and risk control checks.

• Establish a quote quality assessment and market maker grading mechanism to dynamically adjust routing weights.

• Optimize end-to-end latency and throughput for pricing, routing, and transaction processes.

• Design trading risk control and throttling mechanisms that encompass slippage protection, price deviation, replay protection, and gas anomalies.

⛳️ Requirements

• Over 5 years of backend development experience.

• More than 3 years of hands-on experience with Golang.

• Proficient in concurrency models (Goroutine / Channel), standard libraries, and popular frameworks (Gin / Go-zero / Gorm).

• Skilled in microservices architecture and distributed system design, including message queues, distributed locks, circuit breaking, throttling, and idempotent design.

• Expertise in SQL / NoSQL database optimization, familiar with Redis cache design and Kafka asynchronous processing.

• Experience in designing and optimizing low-latency, high-concurrency systems.

• At least 3 years of Web3 development experience, with a solid understanding of blockchain fundamentals, transaction processes, and contract interaction mechanisms.

• Familiar with mainstream public chain interaction mechanisms, specifically with EVM and Solana; knowledge of Sui / Ton is a plus.

• Knowledgeable about the complete on-chain transaction process, including transaction construction, signing, broadcasting, nonce management, and gas strategies, with practical experience in mainnet trading systems.

• Familiar with the pool models, price calculations, and state maintenance of major DEXs (Uniswap V2 / V3, Curve, Raydium, Orca, etc.).

• Hands-on development experience with aggregators (such as 1inch, Jupiter, OKX, etc.), having led or significantly contributed to the design and implementation of routing algorithms, quote aggregation, or transaction execution processes.

• Led the architectural design and implementation of medium to large backend systems from the ground up.

• Strong learning ability, capable of quickly adapting to new technologies, public chains, and protocols, while assessing their practical value and implementation pathways in business.

• Regularly utilizes AI Coding Agents for development, with relevant engineering documentation.

• Practical experience in building Agent Harnesses and writing Skills / Prompts.

• Familiar with concepts such as MCP, Tool Use, RAG, and Eval, along with their engineering implementation boundaries.

• Bonus: Experience in developing market maker systems, quote engines, or order management systems (OMS).

• Bonus: Knowledge of MEV, Mempool monitoring, or Bundle submission (like Flashbots, Jito) is advantageous.

• Bonus: Development experience related to cross-chain bridges, cross-chain transactions, or intent-based trading (CoW, UniswapX, Across, etc.).

• Bonus: Experience in creating internal tools, Skill libraries, or Agent workflows centered around AI Coding.

• Bonus: Contributions to open-source communities or technical blogging.
