Staff AI Engineer

posted by: spj_bot

Location:  Need to be able to work EST timezone.

Remote | Full-time

Compensation: $175K - $250K

We are hiring on behalf of our client who is developing a cutting-edge autonomous agent runtime focused on high-frequency financial environments. While current agents operate effectively as independent units, the next phase of evolution involves building a sophisticated intelligence layer where the entire fleet learns autonomously from real-time market outcomes.

The Staff AI Engineer will be responsible for moving beyond manual propagation of insights to a system where the fleet gets smarter with every trade. This is a high-stakes production role, not a research position. The feedback loop is immediate and measurable: the work produced either enhances agent profitability or it does not. The successful candidate will own the intelligence layer that turns thousands of daily trading decisions into compounding, autonomous growth.

Senior Growth Marketing Manager

About LawnStarter

LawnStarter is the nation's leading marketplace for lawn care and outdoor services, connecting homeowners with service professionals across 120+ markets with $100M+ in annual bookings and marking our second consecutive year of profitability. We're expanding into new verticals beyond lawn care, and Pro supply is what determines how fast we can grow.

About the Growth Team

The Growth team owns customer acquisition — the engine that powers everything else. We bring in 150,000+ new customers per year across Google Ads, LSA, Bing, and organic channels. We're world-class in customer acquisition, and this position extends the team's expertise to the supply side of the marketplace.

The Challenge

Pro supply is our biggest growth constraint and our biggest opportunity. In dozens of markets, we turn away revenue because we don't have enough service professionals to meet demand. Markets with strong Pro density see meaningfully higher customer satisfaction and faster growth.

Organic recruitment and partnerships help, but they don't scale fast enough. We need paid acquisition to work for supply growth, and this role is responsible for building that capability from scratch.
