Visit klaviyo.com/careers to see how we empower creators to own their own destiny. Klaviyo's operational infrastructure, built and managed by our GTM Systems team, powers our GTM engine. We're looking for a Senior GTM Architect, a technical expert with end-to-end understanding of the systems behind marketing, sales, and customer experience, who can reimagine how that system works with an AI-first approach, and who is hands-on enough to build, ship, and de-risk the hardest parts. About the team Our GTM Systems team sits at the center of Klaviyo's GTM engine, powering the operational infrastructure that connects marketing, sales, partnerships, and customer success. We build and own the systems that enable our teams to move quickly, trust their data, and focus on what matters most: helping our customers grow. As we scale, we're rebuilding the marketing, sales, and CX stack around agentic AI as the operating model, not a bolt-on experiment. About the role As the Senior GTM Architect, you are the domain expert for how Klaviyo's marketing, sales, and customer experience systems work together and how they should work differently once AI agents, not just dashboards and workflows, are doing meaningful parts of the job. You own the architecture across our CRM (Salesforce), marketing automation, sales engagement, data enrichment, and CS/support platforms. You translate ambiguous GTM strategy into system architecture (data models, integration patterns, agentic workflows), drive the roadmap by looking around the corner with GTM leadership, and stay hands-on to build and ship meaningful parts of the solution yourself, not just diagram it from a distance. Because of the breadth of this remit, you'll regularly present architecture decisions and AI transformation strategy directly to senior GTM, RevOps, and executive leadership, and need to influence outcomes well above your reporting line. How you'll make an impact Own end-to-end GTM systems architecture: Salesforce, marketing automation, sales engagement, data enrichment, and CS/support platforms, ensuring seamless integration and clean, bidirectional data flow across marketing, sales, and customer success. Ship AI agents into production, not pilots: build and deploy agentic workflows replacing manual GTM work with intelligent, auditable automation. Redesign core GTM processes around AI: lead-to-revenue, opportunity management, renewals/expansion, and support handoffs, evaluating and piloting AI-native tools rather than just administering the existing stack. Stay hands-on: architect and ship meaningful pieces of the solution yourself (Apex, LWC, SOQL, integrations, AI orchestration layers), track your work transparently, and set the technical bar through code review and pairing. Establish data quality and governance standards that keep GTM data trustworthy at scale, and build the reporting infrastructure that leadership relies on to make decisions. Serve as the go-to domain expert and trusted advisor to Marketing, Sales, RevOps, CX, and senior/executive leadership translating complex architectural and AI tradeoffs into language that drives decisions in the room, not just documentation after the fact. Mentor engineers and GTM Systems teammates on system design, AI-native workflow design, and technical tradeoff thinking. What makes you a great fit You've been the technical decision-maker for a complex, multi-system GTM platform (Salesforce or similar) spanning more than one function: marketing, sales, and/or custom
