Senior Solution Architect - Professional Services

Klaviyo Klaviyo · Enterprise · London, United Kingdom · Sales

This role is for a Senior Solution Architect within Klaviyo's Professional Services team. The primary focus is on leading end-to-end strategic customer engagements, from shaping delivery and driving successful implementation to ensuring long-term adoption. The role requires strong enterprise-level project ownership, deep expertise in Klaviyo and martech, and consultative skills to deliver high-impact solutions for complex customers.

  1. Own strategic customer engagements end-to-end, from shaping delivery in partnership with Sales to driving successful implementation and long-term adoption alongside Customer Success and Partner teams.
  2. Operate as a senior individual contributor who is trusted by customers and internal stakeholders to lead through complexity, influence at the executive level, and consistently deliver measurable outcomes for enterprise accounts.
  3. Combine strong delivery/project leadership with technical depth and solution design.
  4. Assist in defining Statements of Work (SOWs) that clearly articulate scope, deliverables, timelines, dependencies, and success metrics for complex technical engagements, ensuring alignment between customer goals and Klaviyo delivery capabilities.
  5. Lead consultative conversations with customers to clarify business objectives, identify risks, and translate desired outcomes into actionable technical implementation plans.
