About the Role

Join an early-stage AI company building an intelligent growth platform for consumer brands. As a founding-level engineer, you will ship product hands-on, shape the technical foundation, and help establish engineering practices as the team grows.

What You'll Do

• Build data infrastructure that tracks merchant lifecycle events and connects actions to outcomes.

• Develop an AI-powered growth system that assesses operations, identifies improvements, and executes changes 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, advertising, and marketing platforms.

• Help define architecture and engineering culture while mentoring engineers and contributing code daily.

What We're Looking For

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

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

• Proficiency with Python and TypeScript, plus experience with tools such as Shopify, Meta Ads API, TikTok Ads API, and Klaviyo.

• Experience leading or mentoring engineers in a player-coach capacity.

• Early-stage startup or 0-to-1 product-building experience, and the ability to prioritize effectively in ambiguous environments.

• Strong communication skills and a track record of sustained contributions in previous roles.
