AI platform building the intelligence layer for modern marketplaces

Senior Product Engineer

New YorkOn-site$160K - $220K5 - 10 years
This team is building the connective tissue between supply and demand in a world drowning in inventory and choice. Their systems learn how buyers actually browse, hesitate, and decide—then reshape the storefront in real time. You'll own product surfaces that merchants and consumers touch daily, shipping features end-to-end from React front-ends through PHP services to MySQL schemas. The work sits at the border of platform reliability and machine-learning experimentation, where a regression costs revenue and a win scales overnight.

What they're looking for

  • 5+ years shipping production code, with deep fluency in React and substantial PHP experience
  • Proven ability to design and optimize relational data models under real query load, ideally MySQL at scale
  • Track record of building features that sit adjacent to ML or ranking systems—not training them, but making them usable
  • Comfort owning ambiguous product problems from zero-to-one, not just executing predefined specs
  • On-site in New York; early founding team members still code-review regularly and expect tight collaboration loops
