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.

Our mission-critical platform provides accurate, cited, and grounded answers at the point of care. Backed by investors including Sequoia Capital and Mayo Clinic, we are seeking a Senior Infrastructure Software Engineer to build the highly reliable and secure backbone for our medical AI platform.

Joining our Core Engineering team, you will have exceptional technical scope and direct impact, translating business objectives into elegant, scalable technical solutions. This is a hybrid role for a backend expert who thrives in a focused startup environment, owning key infrastructure and driving initiatives across reliability, data, and security, specifically handling sensitive medical data at scale.
