• Build reliable integrations with commerce, advertising, and marketing platforms, plus supporting orchestration tools.

• Mentor an engineer while remaining hands-on in day-to-day development.

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

• Working knowledge of Python, TypeScript, Shopify, advertising APIs, and email service provider integrations.

• Experience leading or mentoring one or two engineers, such as in a tech lead, founder, or player-coach role.
