Founding Senior Engineer

About the Role

Join an early-stage AI company building growth automation for consumer brands. As the second engineer, you will ship product hands-on while shaping the engineering culture and architecture, with a focus on reliable systems that help merchants improve 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 evaluates operations, identifies opportunities, and executes changes automatically.

• Own full-stack development of the growth engine, with an emphasis on backend systems and infrastructure.

• Build reliable integrations with commerce, advertising, and marketing platforms, along with orchestration tooling.

• Mentor engineers while remaining hands-on with day-to-day development.

What We're Looking For

• Five to eight years of full-stack engineering experience, with strong backend experience in data infrastructure, event systems, and API integrations.

• Experience building and owning production-grade agentic or LLM-powered systems with third-party API integrations.

• Proficiency with Python and TypeScript; experience with commerce or marketing APIs such as Shopify, Meta Ads, TikTok Ads, or Klaviyo is valuable.

• Experience at a high-growth technology company or well-funded startup, or a strong engineering degree background.

• Experience leading or mentoring one or two engineers, and an ability to bring structure to ambiguous, fast-moving work.

• Early-stage or founding engineering experience is valuable, as are clear communication skills and a record of sustained roles.
