• Provide leadership: define technical vision, mentor developers, conduct code reviews, prioritize backlog, and introduce best engineering practices.

   

Requirements

• 5+ years of commercial backend development experience.
• 3+ years in blockchain/DeFi (EVM, Solana, on-chain data, smart contracts, integrations).
• 2+ years in a Tech Lead or Team Lead role.
• Strong Rust experience: async/tokio, network programming, performance profiling.
• Proficiency with queues/events: RabbitMQ/AMQP, delivery guarantees, retries, DLQ, message contracts.
• Experience with Blockchain/DeFi: ABI, events, integration with Solidity and Solana programs, multi-chain interactions.

• Knowledge of Subgraph (The Graph): schema design, mappings, indexing optimization.

   

Nice to have

• Production experience with Rust (tokio, async, tracing), low-level performance profiling.
• Knowledge of Go (CLI/tools), ETL pipelines for on-chain data, DWH (ClickHouse/BigQuery).
• Experience with Layer 2 (Optimism, Arbitrum), cross-chain bridges/protocols.
• Experience with MEV, mempool monitoring, gas optimization.
• Familiarity with Web3 tools: Foundry, Hardhat, Ethers.js, web3.js, Anchor (Solana).
