How we work

We move fast on hard problems in a nascent market with no set playbook: navigating uncertainty is part of the job. You'll be challenged: anyone can question work and decisions must be justified. We keep a high bar and match it with high support: we help each other unblock and share context openly, with low ego. More about our values: morpho.org/jobs.
Role

The mission of this role is 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, ensuring the platform scales reliably as Morpho grows beyond $10B in TVL, while actively raising the technical bar across the engineering team.
Responsibilities

• 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.
