    📍 Remote | ⏳ Full-time | 🌍 Elys Network

    Build the Future of DeFi on Cosmos

    Elys Network is a high-performance Layer-1 blockchain built on Cosmos SDK, designed for universal liquidity and next-gen DeFi applications. Our flagship product, UniFi, is redefining decentralized trading with on-chain order execution, liquidity aggregation, and yield generation.

    We’re looking for a versatile, energized front-end developer—someone who thrives in a structured setting with a steady rhythm but is just as comfortable charting unknown territory, solving complex problems, and rolling up their sleeves when necessary.

    We respect work-life balance, but when urgent situations arise (rare, but real), you’re the kind of person who steps up to ensure everything runs smoothly—even if it means working outside normal hours on occasion. The most innovative products are built by those who embrace both structure and the unknown, adapting with intention and vision.

    🚨 Disclaimer: If you’re not big on DeFi, please don’t apply. This role requires a deep understanding and passion for decentralized finance, liquidity mechanics, and blockchain interoperability.

    Your Impact
    🖥️ Front-End Development
    • Build and optimize React/Next.js-based Web3 applications (UniFi, staking, governance).
    • Implement CosmJS to interact with CosmWasm smart contracts and IBC transactions.
    • Ensure performance, security, and responsiveness for real-time blockchain interactions.
    • Develop wallet connection flows (Keplr, Ledger, Leap Wallet).
    • Optimize Cosmos IBC asset transfers, relayers, and liquidity flows.
    • Integrate on-chain price feeds, liquidity pools, and order book execution.
    • Own problems end-to-end, balancing structured workflows with the ability to dive into the unknown when needed.
    • Lead and mentor front-end engineers, ensuring code quality and best practices.
    • Work closely with blockchain engineers, product leads, and designers to refine UX.
    • Thrive in ambiguity—some days are methodical, others require deep problem-solving and quick pivots.
    • Be flexible when urgency demands it—it’s rare, but when the stakes are high, we show up.
    🛠️ Must-Have Skills
    • 5+ years in React, Next.js, and TypeScript development.
    • 3+ years of Web3 experience, focusing on Cosmos SDK or CosmWasm.
    • Proficiency in CosmJS, contract queries, and wallet interactions.
    • Strong understanding of DeFi mechanics: AMMs, staking, liquidity pools, order execution.
    • Experience with Cosmos IBC, multi-chain interactions, and asset bridging.
    • Security-first mindset for wallet connections and smart contract execution.
    • Contributions to open-source Cosmos SDK or CosmWasm projects.
    • Founder-style ownership mindset—you don’t wait for permission to solve problems.
    • Ability to thrive in structure while being unafraid to break new ground when needed.
    📈 Bonus Points
    • Knowledge of Golang, Rust, or CosmWasm smart contracts.
    • Experience building DeFi platform dashboards and analytics pages.
    • Familiarity with AI-powered DeFi insights, automation, or predictive analytics.
    Why Join Elys?
    • 🚀 Work on the cutting edge of DeFi—structured, yet always evolving.
    • 🌎 Remote-first, flexible hours, global team of builders.
    • 💰 Starting salary: $75K – $120K, open to discussion. Option for tokens as part of salary—let’s talk.
    • 📈 Long-term career growth in Web3 & DeFi.
    • ⚡ Balanced workflow—steady rhythm when possible, deep problem-solving when needed.
