Overview:

Key Responsibilities

Architecture & System Design

• Spearhead the design and development of decentralized exchange features, including:
  • On-chain order execution and settlement mechanisms.
  • Scalable off-chain infrastructure for indexing, data aggregation, and API delivery.
  • Wallet/key management integrations for seamless UX.
• Architect cross-chain routing across EVM, Solana, Tron, and Bitcoin, orchestrating transactions with varying confirmation times and gas models.
• Implement Circle’s Cross-Chain Transfer Protocol (CCTP) for seamless USDC transfers with robust monitoring and failure handling.
• Lead real-time price discovery with sub-100ms latency from multiple liquidity sources (e.g., Jupiter, OpenOcean, native DEXs).
• Design type-safe address validation systems for diverse chain formats.
• Ensure the reliability, security, and efficiency of smart contracts and off-chain systems.

High-Performance Microservices & Frontend Architecture

• Scale our Python FastAPI microservice architecture
• Design event-driven order lifecycle management with WebSocket connections, status tracking, and recovery.
• Build dynamic gas estimation services across EVM, Solana, Tron.
• Develop liquidity monitoring with real-time balance tracking, rate limiting, and circuit breakers.
• Architect a Next.JS frontend with:
  • High-performance trading interfaces to the standard of e.g. Binance, Hyperliquid, etc.
  • Multi-wallet support (WalletConnect v2, Phantom, MetaMask, hardware wallets).
  • Real-time trading UI with maximally graceful and observable error handling and state management.
  • Secure embedded widget platform with postMessage communication and dynamic theming.

Database, State Management, and Reliability

• Implement event sourcing for immutable trading logs.
• Build multi-level, high-access caching strategies with Redis.
• Integrate Supabase for real-time subscriptions and authentication.

Blockchain Protocol Mastery

• Implement pre-flight transaction simulation with revert reason parsing and slippage protection.
• Build EIP-712, Solana, and Tron signing workflows with nonce management.
• Coordinate bridge protocol integrations for cross-chain asset transfers.

Performance, Security, and DevOps

• Optimize async Python concurrency and React rendering.
• Implement API rate limiting with backoff and quota management.
• Deploy and manage services on GCP (Cloud Run, blue-green deployments).
• Establish observability with metrics, logging, and alerting.
• Enforce security best practices including key management, secret rotation, and secure Docker builds.

Leadership & Process

• Mentor engineers, enforce code quality and testing standards.
• Drive architectural reviews and technology selection.
• Implement incident response protocols, on-call rotations, and post-mortems.
• Improve engineering processes including CI/CD pipelines, code review workflows, and release management.

Qualifications:

• 6+ years of experience in software engineering roles, with a proven track record of leadership and technical expertise.
• Experience in senior roles at small startups, particularly during growth phases and organizational scaling.
• Excellent communication and interpersonal skills, with the ability to effectively collaborate with cross-functional teams and influence decision making.
• Passion for blockchain technology (Crypto native experience is a plus).

Nice-to-Have

• Experience contributing to or maintaining open-source blockchain projects.
• Knowledge of cryptographic concepts, zero-knowledge proofs, or advanced security protocols.
• Prior experience shipping DeFi products.
