[Hiring] DeFi Engineer @Flow Foundation

Role Description

Total value locked (TVL) on Flow is growing quickly, and DeFi is a critical catalyst. As a DeFi Engineer you will drive the next wave of decentralized-finance innovation on Flow—shipping novel protocols, strengthening existing integrations, and inspiring builders across the ecosystem. You’ll pair deep DeFi expertise with Flow-native super-powers such as protocol-level account abstraction, Cadence’s capability-based security model, and seamless EVM equivalence to unlock experiences impossible elsewhere.

What you’ll do

• 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.

Qualifications

• 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.
• Bonus: experience with account-abstraction wallets, formal verification tools, or multi-VM execution environments.

What we’ll accomplish together

• Double the number of high-quality DeFi protocols live on Flow.
• 10× TVL growth through improved capital efficiency and seamless cross-chain liquidity.
• Set new UX/security standards for consumer-friendly DeFi using Flow’s unique capabilities.
• Foster a vibrant community of external DeFi builders and researchers.
