About the Role
Join an early-stage AI company building software that helps consumer brands manage and optimize growth operations. As the second engineer, you will ship product hands-on while shaping the technical foundations and mentoring a fellow engineer.
What You'll Do
Build data infrastructure that tracks merchant lifecycle events and connects actions to outcomes.
Develop agentic systems that assess growth operations, recommend changes, and execute them automatically.
Own full-stack development of the growth engine, with a strong focus on backend systems and infrastructure.
Build reliable integrations with commerce and advertising platforms, along with orchestration tooling.
Help establish engineering practices and architecture while mentoring teammates and contributing code daily.
What We're Looking For
Five to eight years of full-stack engineering experience, with strong backend experience in data infrastructure, event systems, or API integrations.
Production experience building and owning LLM-powered or agentic systems integrated with third-party APIs.
Experience with Python, TypeScript, LLMs, and commerce or marketing integrations such as Shopify, advertising APIs, or email platforms.
Experience at a startup during its growth stage, or a strong engineering education in place of that startup background.
Experience mentoring or leading one or two engineers, and the ability to prioritize work and create structure in ambiguous settings.
Early-stage or founding engineering experience and clear communication skills are valued.
