DeFi Engineer

Flow is a layer one blockchain designed for a new generation of Web3 apps and digital assets. As a DeFi Engineer, you will drive decentralized finance innovation by building and shipping DeFi primitives, expanding partnerships, and enhancing existing protocols.

Responsibilities:

• Build & ship DeFi primitives – Design, implement, and audit smart contracts for AMMs, lending markets, liquid staking, cross-chain bridges, yield strategies, and novel financial instruments
• Expand DeFi partnerships – Collaborate with leading Web3 teams to port or co-create protocols on Flow, guiding them through architecture, security, and launch
• Level-up existing protocols – Profile on-chain activity, identify UX or economic friction points, and deploy improvements that increase capital efficiency and TVL
• Prototype future-state concepts – Explore account abstraction–enabled UX (e.g., gasless transactions, passkeys) and multi-VM composability to invent the next generation of DeFi experiences
• Advocate & educate – Publish reference implementations, write deep-dive blog posts, speak at conferences, and mentor community devs to demystify DeFi on Flow
• Security first – Own end-to-end security: formal verification, fuzzing, audits, monitoring, and rapid incident response

Requirements:

• Software engineering experience focused on Web3/DeFi (Solidity, Move, Cadence, Rust, etc.)
• Hands-on experience shipping and maintaining at least one major DeFi protocol (AMM, lending, bridge, LST, derivatives, etc.) to mainnet
• Strong grasp of smart-contract security patterns, economic/game-theoretic exploits, and incident triage
• Comfort working across the stack: writing Cadence contracts, scripting deployments, instrumenting on-chain analytics, and contributing to dApp front-ends
• Curiosity for emerging primitives (restaking, intent-based execution, L2 interoperability) and the creativity to adapt them to Flow's architecture
• Effective communicator who can translate complex technical ideas to diverse stakeholders
• experience with account-abstraction wallets
• formal verification tools
• multi-VM execution environments
