• Build reliable integrations with commerce and advertising platforms, along with orchestration tools.

• Mentor engineers while remaining actively involved in day-to-day development.

What We're Looking For

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

• Experience building production-grade LLM-powered or agentic systems with third-party API integrations and end-to-end ownership.

• Experience at a startup during its Series A to C growth, or equivalent early-stage and 0-to-1 building experience.

• Experience leading or mentoring one or two engineers, and the ability to bring structure to ambiguous work and prioritize effectively.

• Familiarity with commerce and marketing technology integrations such as Shopify, Meta Ads, TikTok Ads, and Klaviyo.

• Working knowledge of Python, TypeScript, and LLMs, plus strong communication skills.
