About LawnStarter

LawnStarter is the nation's leading on-demand marketplace for lawn care and related services, with over $100M in annual bookings. We're expanding beyond lawn care to become the one-stop shop for all home services—and ProBase is our first major bet in that direction.

About ProBase

ProBase is a free software platform for home service professionals, starting with pool maintenance operators. Our thesis is simple: give pros the tools to run their business for free, help them get more customers, and some will choose to get jobs through our marketplace. We're not a SaaS company charging $50/month—we're building a new on-ramp to the LawnStarter ecosystem.

The Role

This is not a typical product management role. We're looking for someone to take ProBase and run with it—like a founder, but with the backing of LawnStarter's resources, brand, and marketplace.

You'll be an individual contributor with GM-level accountability. Small team, big ownership. You won't be managing a large org; you'll be shipping product, talking to customers, and making the calls that determine whether ProBase succeeds.

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.
