Founding Senior Engineer

About the Role

Join an early-stage AI company building growth tools for consumer brands. As a founding senior engineer, you will build core product systems hands-on, help shape the engineering culture and architecture, and contribute to a team focused on helping merchants improve growth operations.

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

• Mentor engineers while remaining hands-on with day-to-day 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, and API integrations.

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

• Experience leading or mentoring engineers, and the ability to prioritize effectively and create structure in ambiguous environments.

• Familiarity with Python, TypeScript, LLMs, and commerce or marketing integrations such as Shopify, advertising APIs, and email marketing platforms.

• Early-stage startup, founding engineer, or comparable 0-to-1 product-building experience is valued, as is a strong computer science or engineering foundation.
