Reporting directly to the Head of Talent, this is a high-impact, high-autonomy role designed for an ambitious recruiter who wants to shape the hiring strategy of a scaling startup.

Key Responsibilities:

Founding Engineer (Trading Infrastructure)

Location: New York, London (Office)

Compensation: Competitive

We are building the next generation of global trading infrastructure. Designed for sub-millisecond execution and institutional depth, our platform powers spot, perpetuals, and prediction markets on a unified liquidity engine. Built by a team of Wall Street veterans and crypto-native engineers, we are moving beyond the limitations of current exchanges to create a high-performance network that spans across asset classes with zero compromise.

As a Founding Engineer, you will be a core architect of our trading ecosystem. This is a high-leverage role where you will be trusted with substantial autonomy to make foundational design decisions. Working directly with the founders, you will bridge the gap between high-finance performance and decentralized innovation to deliver a best-in-class trading experience.

Key Responsibilities:

Staff Quantitative Engineer (Onchain Market Primitives)

Location: Remote - US remote preferred, open to Europe for strong candidates

Compensation: Competitive

About the Company We are building a foundational layer for perpetual markets centered on onchain economic activity. Instead of pricing speculative assets or narratives, our platform allows traders and autonomous agents to take directional exposure to the growth or decay of the onchain economy—including protocols, infrastructure, and capital flows. Our markets are deployed directly into the Hyperliquid ecosystem, with discovery and execution optimized through a dedicated application suite. This is early, foundational work at the intersection of quantitative finance, crypto market structure, and onchain data systems.

Role Overview We are seeking a Staff Quantitative Engineer to own the design and evolution of our core market primitives. This is not a research-only or support role; you will own markets end-to-end, from first-principles design and specification to post-launch iteration based on real trading behavior. As a technical lead and thought partner to the founders, you will set the standard for how we design indexes, oracles, and market integrity systems.
