About Us
We’re a fast-growing team building a high-performance decentralized exchange (DEX) designed for cross-chain interoperability, low-latency trading, and advanced DeFi features. Join us to solve complex backend challenges in a decentralized environment.
Responsibilities
Design, build, and maintain scalable backend systems for order matching, liquidity aggregation, and real-time data processing.
Develop REST/WebSocket APIs for frontend and external integrations (wallets, block explorers, oracles).
Optimize database architecture (PostgreSQL, Redis, TimescaleDB) for high-frequency trading data.
Implement blockchain node interactions (EVM, Cosmos, Solana) for transaction broadcasting and event monitoring.
Collaborate with smart contract developers to reduce latency and gas costs.
Ensure security best practices (rate limiting, DDOS protection, data encryption).
Monitor and improve system performance (load balancing, sharding, cloud infrastructure).
Requirements
3+ years of backend development (Node.js, Go, Python, or Rust).
Strong experience with API design (GraphQL, gRPC is a plus).
Proficiency in database optimization (SQL/NoSQL, indexing, caching).
Familiarity with blockchain RPC calls (JSON-RPC, Web3 providers).
Knowledge of containerization (Docker, Kubernetes) and cloud services (AWS/GCP).
Understanding of Web3 security (transaction signing, replay attacks).
Ability to write clean, auditable code with testing (Jest, Mocha).
Nice to Have
Experience with order book engines or AMM algorithms.
Contributions to open-source blockchain projects.
Knowledge of ZK-proofs or MPC protocols.
We Offer
100% remote work with flexible hours.
Competitive salary + token incentives.
Work alongside top-tier blockchain engineers.
Opportunity to shape the future of DeFi infrastructure.
