Résumé du poste

Morpho, a leading DeFi lending protocol, seeks a Senior Software 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 for scalable growth.

You will lead 5–10 engineers, set coding standards, and drive observability with OpenTelemetry, Grafana and Sentry while maintaining strong ownership, clear communication, and a focus on performance in a fast-moving, ambiguous market.

Qualifications

• 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.

Responsabilités

• Architect and own end-to-end delivery of DeFi products with billions in TVL, from React/Next.js frontends 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.
