The Opportunity

Build the next-generation e-commerce accelerator powered by Agentic AI, where autonomous AI agents handle repetitive execution and analytics while experienced humans focus on brand relationships and strategic decision-making.

We are looking for a Founding Technology Hire & CTO to build this vision alongside the founders. This is a hands-on builder role: you are the technology, data, and AI function.

What You Will Own

  • The Agentic Core: Architect and deploy the AI infrastructure running the entire operation, including listing creation and optimization, catalog ingestion, buy-box monitoring, dynamic pricing, and supply-chain signals.
  • The Data Spine: Build clean, real-time data pipelines integrating marketplace APIs, including Amazon SP-API, logistics, and finance. Calculate live cost-to-serve down to the SKU level.
  • Multi-Channel Scalability: Design a modular architecture starting with Amazon and expandable to TikTok Shop, D2C through Shopify, and European marketplaces without requiring a rebuild.
  • Build vs. Buy Decisions: Select the right frameworks, LLM models, and vendors, knowing when to build and when to integrate.

What You Bring

  • Production Agentic AI Experience: Shipped and operated agentic or LLM-based systems in real operational environments, with an understanding of breaking points, running costs, and where human-in-the-loop is required.
  • Marketplace & E-commerce Depth: Hands-on experience with Amazon SP-API, Ads data, buy-box dynamics, and inventory management.
  • Data-Centric Engineering: Proficiency in data warehousing, pipelines, and commerce data models covering products, orders, fees, and margins.
  • Hands-on Builder Mindset: Strong active coding ability in backend, data engineering, AI/ML, or cloud architecture.
  • Commercial Instinct & Early-Stage Temperament: Focus on contribution margins and the ability to thrive in fast-paced, ambiguous environments.

Who You Are

  • A partner who wants to build from day one and share meaningfully in its financial success.
  • A builder rather than a manager, focused on building architecture instead of organizational charts.
  • Driven by curiosity, ownership, and trust; able to move fast while maintaining close attention to detail where failure is not an option.

What We Offer & The Process

  • Competitive base salary, performance bonus, and equity negotiated based on experience.
  • Meaningful, early-stage equity negotiated transparently upfront.
  • Direct partnership with experienced founders and complete technical autonomy.
  • Hiring process includes initial culture-fit chats, a deep-dive architectural discussion, full commercial visibility, and a paid micro-project before any permanent commitment.
