Job description

Overview

Founded in 2013, Gate is one of the world's earliest and most trusted cryptocurrency exchanges, serving over 53 million users globally. Ranked among the top three exchanges worldwide, Gate supports spot, futures, and margin trading alongside wealth management products across 4,600+ cryptocurrencies. With thousands of employees across key global markets — most working fully remotely — Gate is building the financial infrastructure of the next era of the internet. We hire people who move fast, think independently, and want real ownership of their work.

Why this role

Gate's on-chain data and trading infrastructure spans Solana, EVM chains, and a growing roster of protocols — and the team building it is scaling fast. You're joining at the moment we raise the ceiling: high-throughput data pipelines, real-time monitoring, and the backend layer that ties on-chain execution to off-chain business logic. Ship it right and you'll have owned the kind of distributed, multi-chain backend that most engineers only read about.

What you'll do

• Architect and own the backend for core products — DEX aggregator, on-chain data services, 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 — transaction signing, state tracking, 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'll bring

• Has designed and shipped production-grade distributed backend systems — owns the full picture from API to database to deployment, not just one layer
• Has built on-chain integrations in production: block parsing, contract interaction, event listening across EVM or Solana, with real debugging experience when things break at the protocol level
• Has run Golang services at scale — concurrent workloads, Goroutine/Channel patterns, production incidents resolved, not just toy projects
• Understands 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

Bonus

• Has worked across more than two chains (e.g. EVM, Solana, Sui) and navigated their differences in transaction models and data structures
• Has operated 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
