About the role

About the Role

Join an early-stage AI company building growth tools for consumer brands as its second engineer. This hands-on player-coach role will shape the product, engineering culture, and architecture, with a focus on reliable systems that help merchants improve their growth operations.

What You'll Do

  • Build data infrastructure that tracks merchant lifecycle events and connects actions to outcomes.
  • Develop an agentic growth system that assesses operations, identifies opportunities, and automates changes.
  • Own full-stack development of the growth engine, with a strong focus on backend systems and infrastructure.
  • Build reliable integrations with commerce, advertising, and marketing platforms, along with orchestration tooling.
  • Mentor engineers while contributing hands-on to daily product development.

What We're Looking For

  • Five to eight years of full-stack engineering experience, with strong backend experience in data infrastructure, event systems, or API integrations.
  • Production experience building and owning agentic or LLM-powered systems that integrate with third-party APIs.
  • Experience with Python, TypeScript, LLMs, and commerce or marketing APIs such as Shopify, Meta Ads, TikTok Ads, or Klaviyo.
  • Experience leading or mentoring engineers, and the ability to prioritize work and create structure in ambiguous settings.
  • Experience at an early-stage startup, including during Series A to C growth, or a strong engineering education background.
  • Strong communication skills and a consistent record of contributing to engineering teams.
