Descripción de la vacante

Morpho in Paris or remote is seeking a Senior Fullstack Architect to own the technical architecture and end-to-end delivery of Morpho's product suite, spanning React frontends, GraphQL APIs, and on-chain data systems.

Formación

• 8-10+ years building fullstack applications at scale.
• Proven track record architecting high-availability systems handling millions of requests daily.
• Deep TypeScript expertise across client and server: React/Next.js, GraphQL (Apollo Server), Node.js, and typed contract interactions (viem).
• Hands-on experience building or maintaining on-chain data indexers (Ponder, Subsquid, or similar) and working knowledge of EVM event structures.
• Track record of leading technical initiatives across multiple teams without direct authority.
• Comfort operating in fast-changing, ambiguous environments without needing a defined playbook.
• Strong ownership mindset: you drive things to completion and don't wait to be asked.
• Clear, crisp async communication: you write well and can explain complex technical decisions simply.

Responsabilidades

• Architect and own end-to-end delivery of DeFi products with billions in TVL, from React/Next.js frontends through GraphQL/REST APIs to blockchain data indexers, ensuring sub-second response times for users.
• Design and implement the API and SDK strategy enabling hundreds of integrators to build on Morpho's infrastructure, including versioning patterns, developer experience standards, and real-time streaming systems.
• Build and optimize high-performance data systems processing millions of on-chain events across 15+ blockchains, using intelligent caching and query optimization to maintain reliability at scale.
• Lead technical architecture reviews and establish coding standards that raise the technical capability of 5-10 engineers across product teams.
• Own observability and incident response across the stack, using OpenTelemetry, Grafana, and Sentry to ensure reliability for users and integrators.
