About the Role Klaviyo is seeking a Lead MarTech & AI Solutions Architect — an individual contributor role for someone who wants deep, hands-on ownership. In this role, you'll design and build the end-to-end architecture of how marketing data moves through our systems, from initial lead and data intake through to conversion, embedding AI and automation directly into that journey to accelerate it. In this role, you'll also architect and own a centralized marketing hub spanning the full marketing lifecycle — from budget allocation and planning, through campaign execution, to using performance insights to accelerate the next planning cycle and improve ROI. This role carries high ownership and visibility: you're the architect who understands how every system connects, why it's built that way, and where it needs to go next — building the technical foundation that turns customer journeys and personalization, planning cycles, and cross-functional decisions into a single, connected ecosystem. How You'll Make a Difference Design and build AI-powered marketing capabilities into our systems, from generative AI use cases to predictive scoring and intent-based automation, that accelerate the intake-to-conversion journey. Serve as the technical owner of how marketing systems integrate with one another — proactively catching where data breaks or logic conflicts, and implementing the architectural solutions needed to evolve the ecosystem to support business growth
