Senior Blockchain Architect (2 Position)
Experience Level: Senior
About the Role
We are looking for an experienced 5+ years Senior Blockchain Architect to lead the design, development, and security of our decentralized ecosystem. This role is ideal for someone with deep expertise in smart contract systems, wallet infrastructure, and DeFi protocols—plus a strong background in indexing blockchain data and embedding security at every layer of the stack.
You will work closely with founders, developers, and product teams to architect robust, scalable, and secure blockchain infrastructure, including Subgraph indexers, non-custodial wallets, and multi-chain DeFi systems.
Key Responsibilities
· Design, architect, and audit smart contract systems (Solidity + Hardhat/Foundry) for high-stakes financial applications; enforce testing, upgradeability, and audit readiness.
· Build and optimize Subgraphs with The Graph (schema design, indexing performance, reorg resilience) to power scalable on-chain data for dApps.
· Guide secure frontend integration (Next.js, wagmi/viem, Ethers.js) across testnet/mainnet, including typed contract bindings, TX simulation, and feature-flagged rollouts.
· Architect backend services (Node.js + TypeScript, MongoDB/Redis/queues) for wallet-driven and tokenized features; design APIs/webhooks for trading, settlement, and analytics.
· Deliver DeFi modules (staking, yield, liquidity pools) with clear risk controls, oracle strategy, fee models, and upgrade paths.
· Own non-custodial wallet architecture (EVM + non-EVM) for React Native and MV3 browser extensions: key management flows, signing UX, recovery, WalletConnect v2.
· Integrate on/off-ramps and liquidity providers (e.g., B2C2) and DEX aggregators (e.g., 1inch/0x) with best-execution logic, slippage controls, and compliance hooks.
· Implement DevSecOps: secure SDLC, CI/CD for contracts & apps, secrets management, SAST/DAST (Slither/Echidna/etc.), runtime monitoring (Tenderly/Defender/Forta), and incident response.
· Establish observability & SRE practices: block-lag/mempool monitoring, alerting, log aggregation, dashboards, and on-call runbooks for chain events and reorgs.
· Mentor engineers; set coding standards, review designs/PRs, and contribute to technical roadmap, scalability, and security strategy.
