What the job involves

• At Klaviyo, the Sales team prides itself on being made up of marketing and product experts
• While many companies hire pre-sales Solutions Engineers simply to give demos, fill out questionnaires, and explain setups, that approach makes us yawn
• We’re looking for a Senior Solutions Engineer who brings deep technical mastery, strategic thinking, and the ability to own the most complex, high-stakes Enterprise deals
• This is a high-impact individual contributor role for someone who thrives in ambiguity, rolls up their sleeves to master our product at a molecular level, and uses AI and automation to punch above their weight
• As a Senior SE, you’ll be a trusted advisor to both customers and our sales organization — leading technical strategy in 6–7 figure deals, owning solution design, and setting the standard for Solutions Engineering excellence through your work
• We’re technical sellers who drive revenue by winning complex Enterprise deals. Our job is to own the technical win — building champions, proving value, and ensuring prospects choose Klaviyo over the competition
• We work directly with customers to architect solutions that integrate seamlessly into their tech stacks, taking a consultant-first approach that builds confidence and secures technical buy-in
• Beyond closing deals, we use customer engagements as opportunities to prototype and ship improvements to Klaviyo. Recent team projects include AI-powered demo data generators, a public Chrome extension for troubleshooting API calls, web SDK injectors, and templatized mobile apps that showcase our SDK capabilities
• Own technical strategy for the most complex Enterprise opportunities, navigating multi-layered stakeholder environments, competitive pressures, and sophisticated buying processes with minimal oversight
• Drive advanced technical discovery, uncovering nuanced pain points and proactively identifying differentiation opportunities
• Host technical workshops that align solutions to business outcomes, demonstrating executive presence and strategic communication
• Architect and execute Proof of Value plans that secure technical selection over competitors
• Partner closely with AEs on deal strategy, bringing competitive intelligence and industry expertise to influence outcomes
• Serve as a domain expert in marketing technology, CDPs, AI-driven personalization, analytics, and eCommerce
• Act as a go-to resource for competitive and industry landscape questions
• Build strong relationships with R&D, collaborating to drive positive outcomes and influence Klaviyo’s roadmap
• Contribute high-impact content to the SE Learning Library and mentor peers through example
• Become an expert across Klaviyo’s platform, from data pipelines and integrations to technical trade-offs between implementations
• Develop broad, advanced familiarity with web development, APIs, cloud computing, and modern software development practices
• Confidently coach experienced engineers on complex solution design
• Leverage AI tools and automation to scale impact and improve customer outcomes
• Prototype solutions and build proof-of-concepts that clearly demonstrate Klaviyo’s differentiation
