At Klaviyo, the Sales team prides themselves on being marketing and product experts. While most companies hire pre-sales Solutions Engineers to just give demos, fill out questionnaires, and only explain setups, that makes us yawn.

We're looking for a Solutions Engineer who brings deep technical mastery, strategic thinking, and the ability to own the most complex, high-stakes Mid-Enterprise deals. This is a high-impact individual contributor role for someone who gets energized by ambiguity, rolls up their sleeves to master our product at a molecular level, and uses AI and automation to punch above their weight.

As an 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 SE excellence through your work.

We're technical sellers who drive revenue by winning complex deals. Our job is to lead 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 for showcasing 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 for you.
