Web3 Backend Engineer

As a Web3 Backend Engineer at Gate, you'll architect and own the backend infrastructure powering a top-three global cryptocurrency exchange serving over 53 million users. You're joining at a critical scaling moment: you'll build the high-throughput data pipelines, real-time monitoring, and distributed backend layer that ties on-chain execution across Solana, EVM chains, and emerging protocols to off-chain business logic.

What you'll do

• Architect and own the backend for core products including DEX aggregator, on-chain data services, and wallet management, with a hard focus on throughput, latency, and uptime under load
• Build and maintain the on-chain data layer: block ingestion, event parsing, structured storage, and real-time alerting across Solana, EVM, and other target chains
• Design high-performance APIs (RESTful, gRPC, WebSocket) and own the interaction contract between on-chain execution and off-chain services, including transaction signing, state tracking, and event routing
• Build the off-chain integration layer for smart contract calls across EVM and Solana, including multi-chain event aggregation and transaction routing
• Drive infrastructure decisions: microservices architecture, containerised deployment via Docker and Kubernetes, database and cache layer (SQL, NoSQL, Redis), and async processing via Kafka

What you bring

• You have designed and shipped production-grade distributed backend systems, owning the full picture from API to database to deployment, not just one layer
• You have built on-chain integrations in production: block parsing, contract interaction, and event listening across EVM or Solana, with real debugging experience when things break at the protocol level
• You have run Golang services at scale with concurrent workloads, Goroutine/Channel patterns, and production incidents resolved in real systems, not toy projects
• You understand consensus mechanics and P2P network fundamentals well enough to reason about what chains do and don't guarantee, and to design systems that handle edge cases accordingly

Nice to have

• Experience working across more than two chains (for example, EVM, Solana, Sui) and navigating their differences in transaction models and data structures
• Hands-on operation of Kubernetes clusters in a production environment, including CI/CD pipeline ownership
• Hands-on experience with DEX protocols, on-chain routing logic, or wallet custody systems
