About the role

About the Role

Join an early-stage AI company building growth tools for consumer brands. As the second engineer, you will build core product systems hands-on while shaping the engineering culture and architecture.

What You'll Do

  • Build data infrastructure that tracks merchant lifecycle events and connects actions to outcomes.
  • Develop agentic systems that assess growth operations, identify opportunities, and execute improvements automatically.
  • Own full-stack development of the growth engine, with a strong focus on backend systems and infrastructure.
  • Build and maintain reliable integrations with commerce and advertising platforms, along with orchestration tooling.
  • Mentor engineers while contributing directly to daily product development.

What We're Looking For

  • Five to eight years of full-stack engineering experience, with strong backend skills across data infrastructure, event systems, and API integrations.
  • Experience building and owning production-grade agentic or LLM-powered systems that integrate with third-party APIs.
  • Familiarity with Python, TypeScript, LLMs, and commerce or marketing integrations such as Shopify, Meta Ads, TikTok Ads, or Klaviyo.
  • Experience leading or mentoring engineers, and a track record of prioritizing effectively in ambiguous environments.
  • Early-stage startup or founding engineer experience, or experience joining a startup during its growth stage. Strong computer science fundamentals are valued.
  • Clear communication skills and a consistent record of meaningful tenure.
