About Morpho

Morpho is a leading Decentralized Finance (DeFi) lending protocol that raised $70 million from Ribbit Capital, a16z crypto, Coinbase Ventures, Variant, Brevan Howard, Pantera, Blocktower, and 50 others to build an open lending network giving anyone, anywhere, access to the best possible terms. Morpho is experiencing explosive growth, with over $10 billion in deposits on the network, solidifying itself as the new standard for DeFi lending. Now, Morpho is scaling its team of contributors to establish itself as a cornerstone, not just of DeFi, but of a new internet-native financial system.

Our Mission

Morpho's mission is to power human ambition with open access to capital. Human ambition has no borders, but the capital to fuel it does. Today's financial system is closed and fragmented. No one sees all opportunities, most overpay, and some are excluded entirely. We believe capital should flow efficiently to where it's needed most - giving anyone, anywhere, access to the best possible terms.

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.

What Success Looks Like

First 30 days

Shipped a high-impact feature end-to-end that demonstrates competency across the full stack. Completed an architecture review of current systems and proposed a modernization roadmap. Built working relationships with key stakeholders across product, protocol, and business teams.

First 4 months

Leading delivery of a major product initiative from scoping to production. Driving measurable improvements to API p95 latency through caching, query optimization, and architectural changes.

In 1 year

Owns technical architecture for an entire product vertical, with proven reliability and performance metrics. Recognized as the technical authority for fullstack architecture decisions across the organization.

Must-have Experience & Skills

• 8-10+ years building fullstack applications at scale, with demonstrated impact on business metrics.
• 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).

• 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.
• Team-first approach: you make the engineers around you better, not just the codebase.
• Humble.
