Frontend Engineer - job 1 of 2

Senior Frontend Engineer - High-Performance Financial Platform

Location: New York, San Francisco (Office)

Compensation: $185K - $300K

We are hiring on behalf of our client who are building a revolutionary Multi-Asset Margin solution for one of the fastest-growing ecosystems in decentralized finance. Currently, the crypto derivatives sector generates $20B–$30B in annual revenue, and multi-asset margin accounts for over 86% of all trading activity. Their mission is to bridge the gap between diverse collateral types and high-performance trading.

Their platform allows users to post variable forms of collateral without needing to sell their assets for stablecoins. By building sophisticated blockchain-integrated systems "under the hood," they extend liquidity to the venues of their users' choice, bringing the market to them rather than forcing them to navigate multiple fragmented platforms.

As a member of their Product & Platform team, you will build and maintain the applications that power these services. You will collaborate closely with designers, backend engineers, and product managers to deliver responsive, high-performance user interfaces that define the future of DeFi trading.

The Frontend Engineer will be responsible for the full lifecycle of application development, focusing on performance, user experience, and real-time data visualization.

• UI/UX Development: Design, build, and maintain full-featured websites and user interface (UI) components optimized for both web and mobile experiences.
• Design Collaboration: Collaborate closely with product designers to translate wireframes and mockups into responsive, accessible, and pixel-perfect applications.
• Performance & Optimization: Optimize application performance, leveraging modern techniques like Server-Side Rendering (SSR) and Content Delivery Network (CDN) delivery. Deeply profile applications using tools like Lighthouse.
• Data Visualization: Develop performant, interactive charts and visualizations to display real-time financial data and complex market insights.
• API Integration: Integrate application interfaces with various services, including REST APIs and WebSockets, and expertly manage complex client-side state and caching strategies.
• DevOps & CI/CD: Configure and maintain CI/CD pipelines for seamless builds, previews, and reliable rollbacks.

• Experience: 3+ years of professional experience building and shipping high-quality frontend applications.
• Core Technologies: Expert proficiency in JavaScript/TypeScript and React.
• Styling Expertise: Strong CSS fundamentals (e.g., Flexbox, Grid, responsive/mobile-first design) and hands-on experience with Tailwind CSS.
• Performance: Deep understanding of browser rendering, runtime performance, and proficiency in performance profiling tools.
• Testing: Experience with modern testing frameworks (e.g., Jest, Mocha) and a dedication to writing maintainable test suites.
• Data Handling: Familiarity with modern data-visualization libraries (e.g., Chart.js, D3) and demonstrated experience handling high-volume, real-time data streams.
• Legal: Authorized to work in the United States.

• Salary: $185,000 - $300,000 annual base salary.
• Equity: Generous company equity package.
• Health: Comprehensive medical, dental, and vision insurance options with Health Savings Account (HSA) availability.
• Time Off: Paid vacation and holidays.
• Retirement: Retirement plan (e.g., 401(k)) with employer matching contributions.
