About the role

About the Role

Join an early-stage AI company building growth tools for consumer brands. As a hands-on player-coach, you will own core engineering work while helping shape the architecture and engineering culture.

What You'll Do

  • Build data infrastructure that tracks merchant lifecycle events and connects actions to outcomes.
  • Develop agentic growth systems that assess operations, identify opportunities, and execute changes automatically.
  • 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, alongside orchestration tools.
  • Mentor engineers while remaining actively involved in day-to-day development.

What We're Looking For

  • Five to eight years of full-stack engineering experience, with strong backend skills in data infrastructure, event systems, and API integrations.
  • Hands-on experience building and owning production agentic or LLM-powered systems integrated with third-party APIs.
  • Experience with Python, TypeScript, LLMs, and commerce or marketing integrations 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 environments.
  • Early-stage startup or founding engineer experience, or experience at a growing startup before it reached a large scale.
  • Strong communication skills and a consistent record of contributing to engineering teams.
