A quick run-down of the job We’re looking for a Senior Frontend Engineer to join our Perps / Orderbook squad.
At LI.FI, we build infrastructure that connects users to liquidity across chains. Our Hyperliquid integration powers seamless onboarding into perpetual trading, allowing users to bridge assets, swap tokens, and deposit collateral directly into Hyperliquid markets.
In this role, you’ll build high-performance DeFi interfaces and liquidity onboarding flows that connect users to decentralized perpetual futures exchanges (like Hyperliquid, Lighter, etc). This includes cross-chain bridging, swaps, and deposit flows powered by LI.FI infrastructure, enabling seamless access to decentralized perpetual trading.
Please note: you must be located in EMEA or LATAM.

What you’ll do
Build and maintain DeFi interfaces and integrations powered by LI.FI infrastructure.
Develop cross‑chain user flows including bridging, swapping, and routing assets across multiple chains.
Implement onboarding experiences that connect users to decentralized perpetual futures exchanges, such as Hyperliquid, enabling seamless asset movement and liquidity access.
Integrate frontend applications with LI.FI APIs, SDK, and widget.
Build data‑rich interfaces that surface routing options, transaction status, and cross‑chain execution details.
Collaborate closely with backend, product, and design teams to design robust cross‑chain user experiences.
Ensure performance, reliability, and maintainability through testing, debugging, and optimization.
Contribute to frontend architecture and reusable UI components used across LI.FI products and integrations.
What makes a good candidate We’re looking for engineers who are comfortable building complex frontend systems in fast‑moving environments. The current UX is mobile‑focused, but the product is expanding to a multi‑device experience with a rich full desktop design.
Requirements
6+ years of frontend engineering experience
Strong experience with React and TypeScript
Experience building complex, data‑heavy user interfaces
Previous experience working with DeFi applications, crypto infrastructure, or Web3 products
Understanding of perpetual futures trading infrastructure, with exposure to venues such as Hyperliquid, Lighter, Extended, or similar DeFi/CEX derivatives platforms.
Experience working with real‑time data (WebSockets or streaming systems)
Strong understanding of API integrations and frontend architecture
Ability to translate designs from Figma into polished interfaces
Strong communication and collaboration skills
Nice to have
Experience building cross‑chain or multi‑chain DeFi applications
Experience with bridging, swaps, or liquidity routing systems
Open‑source contributions or maintained public repositories
If your experience doesn’t perfectly match the description but you’re excited about building high‑performance crypto trading interfaces, we’d still love to hear from you.
