Founding Senior Engineer

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.
