Resumo da oferta

Gate is building a real-time, multi-chain Web3 market data platform. You will own the backend for on-chain data, exchange data feeds, and streaming services that power traders and strategies.

The role focuses on low-latency, scalable architecture across EVM and Solana, with a strong emphasis on reliability and observability. Ideal candidates have production-grade Java or Go experience, hands-on with Akka/Pekko or Redis Streams, and a track record delivering real-time data systems in crypto or

Qualificações

• Architected and shipped a real-time data platform from scratch.
• Production-level Java or Go with deep internals.
• Experience with Akka/Pekko, Reactor/RxJava, or Redis Streams.
• Web3 and on-chain data middleware across EVM and Solana.
• Experience incorporating AI coding agents into development workflows.

Responsabilidades

• Architect and build the backend for Gate's Web3 market data system—from ingestion to distribution.
• Design and ship a low-latency, high-throughput compute layer with strong stability.
• Build real-time data push services (WebSocket, gRPC) for multiple consumers.
• Lead on-chain data platform design: node integration, parsing, and storage.
• Abstract multi-chain data models and create a reusable parsing framework.
• Instrument the platform with real-time monitoring and alerting.

About Gate

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

Real-time market data and on-chain data infrastructure are the foundational layer everything else at Gate sits on — trading, strategy, wallets, prediction markets. The current system needs to scale to handle the data complexity of a multi-chain world: EVM, Solana, Move-based chains, DEX pools, order books, and event streams, all feeding downstream consumers with sub-second latency. You'll own the architecture and delivery of this layer, from node ingestion through to structured data assets that product teams actually build on. In 18 months, you'll have shipped a multi-chain data platform with demonstrable latency, throughput, and reliability benchmarks — and built the parsing framework the team extends to every new chain we integrate.

What you'll do

• Architect and build the backend for Gate's Web3 market data system — on-chain prices, DEX pool data, order books, trade flows, and candlestick data — across the full pipeline from ingestion to distribution


• Design and ship a low-latency, high-throughput, horizontally scalable real-time compute layer; own stability, consistency, and freshness under high-concurrency load


• Build real-time data push services (WebSocket, gRPC Streaming) that serve frontend, strategy, and trading consumers with the latency profiles they need


• Lead the design and delivery of the on-chain data platform — node integration, block parsing, event decoding, internal transaction reconstruction, and structured storage


• Abstract multi-chain data models and build a reusable parsing framework that generalises across EVM, Solana, and emerging chains, reducing the cost of every new integration


• Instrument the platform with real-time monitoring and alerting across node health, data latency, completeness, and parsing anomalies

What you'll bring

Non-negotiables

• Has architected and shipped a real-time data platform or on-chain data middleware from scratch — can walk through the key design decisions, the failure modes encountered, and how the system behaves under load


• Production-level Java or Go experience with the internals to match: JVM tuning and Spring ecosystem for Java; Goroutine/Channel concurrency model and primary frameworks (Gin, Go-zero, Gorm) for Go


• Has built with real-time compute primitives in production — state management, backpressure, fault tolerance, Exactly-Once semantics; hands‑on with Akka/Pekko, Reactor/RxJava, or Redis Streams


• Deep Web3 engineering experience across EVM and Solana: understands Log Decode, ABI parsing, Trace and internal transaction handling, and has abstracted multi-chain data models in a production context


• Uses AI coding agents as a standard part of the development workflow — has engineering artefacts to show for it (Agent harnesses, Skills, Prompts), not just familiarity

Bonus

• Hands‑on experience with Move-based chains (Sui or Aptos)


• Has built or evaluated MCP, Tool Use, RAG, or Eval pipelines in an engineering context — understands where they add leverage and where they don't
