Protocol Security Engineer

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 ensure the security and robustness of Morpho's smart contracts by conducting formal verification, security reviews, and managing bug bounty programs to ship safer protocols and reduce audit cycle times.

Responsibilities

• Implement formal verification rules using Certora on Morpho smart contracts to validate critical invariants and reduce vulnerabilities before deployment.

• Conduct comprehensive security reviews of protocol smart contracts to identify critical bugs and strengthen the attack surface before audits.

• Own the bug bounty program by triaging submissions, communicating with security researchers, and coordinating response to critical findings.

• Build periphery smart contracts that integrate with the core protocol to extend functionality while maintaining security standards.

• Research emerging attack vectors and new vulnerability classes to keep the team ahead of threats and inform security best practices.

• Represent Morpho's security approach at conferences, meetups, and through published research to build credibility in the security community.

What Success Looks Like

In your first 30 days

You will gain a solid understanding of Morpho v1 and vault v2 architecture, and implement initial formal verification rules using Certora on Vault/Market V2 contracts.

By Month 4–6

You will have complete understanding of Morpho v1 and v2, autonomously formulate and implement the most important contract invariants and own triage and validation of our smart contract bug bounty program.

By Month 12

You will have made meaningful security contributions that increase robustness and reduce attack surface, identified new attack vectors, and distilled security best practices that the entire Protocol team relies on.
