About the Opportunity 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. What We Do as Solutions Engineers 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. If you’re a creator excited by winning high-stakes deals, prototyping technical solutions, and driving strategic revenue outcomes, this could be the role for you.
