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.
