Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # DeFi Engineer - **Company:** Flow LLC - **Location:** United States (Remote available) - **Contract:** Permanent contract - **Skills:** Formal Verification, Fuzz Testing, Software Engineering, Solidity, Web3.js - **Published:** July 13, 2026 - **Apply:** https://careers.kula.ai/flow-com/6376 ## About the Role * 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. ## Description Remote Hiring Remotely in United States Mid level Remote Hiring Remotely in United States Mid level As a DeFi Engineer at Flow, you will build and ship DeFi primitives, expand partnerships, enhance existing protocols, prototype innovations, and ensure security while educating the community about DeFi on Flow. The summary above was generated by AI About Flow Foundation Flow is a layer one blockchain designed from the ground up as a platform for a new generation of Web3 apps, games, and the digital assets that power them. Flow is home today to millions of users and apps from top tier creators including Genies, Cryptoys, Doodles, and Dapper Labs (NBA, NFL, Disney) as well as industry leaders such as Mattel (Barbie, Hot Wheels), LiveNation / Ticketmaster, and many more. Our mission is to take Web3 mainstream by making blockchain technology simple, safe, and delightful for builders and consumers alike. We operate as a distributed, low-hierarchy organization where humble, inquisitive entrepreneurs thrive. Why this role matters 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. ## Related Videos - [Smart Contract fundamentals - My first DApp](https://www.wearedevelopers.com/videos/52-smart-contract-fundamentals-my-first-dapp) - [Trust as the Key Concept in Future Mobility](https://www.wearedevelopers.com/videos/581-trust-as-the-key-concept-in-future-mobility) - [How will artificial intelligence change the future of software testing?](https://www.wearedevelopers.com/videos/85-how-will-artificial-intelligence-change-the-future-of-software-testing) - [When testing just doesn’t cut it](https://www.wearedevelopers.com/videos/720-when-testing-just-doesn-t-cut-it) - [​Road to Web3](https://www.wearedevelopers.com/videos/584-road-to-web3) - [Blockchain, NFT and smart contracts for my application](https://www.wearedevelopers.com/videos/877-blockchain-nft-and-smart-contracts-for-my-application) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Basic And Advanced Networking in Dart and Flutter](https://www.wearedevelopers.com/magazine/112-basic-and-advanced-networking-in-dart-and-flutter) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers)
