About the Role
At Klaviyo, our Sales team prides itself on being experts in marketing and product strategy. Unlike many companies that view pre-sales Solutions Engineers as mere demonstrators, we seek to elevate this role.
We are in search of a Lead Solutions Engineer who possesses deep technical expertise, strategic acumen, and the capacity to manage the most intricate and high-stakes Large Enterprise deals. This impactful individual contributor role is ideal for someone who thrives in ambiguity, dives deep into mastering our product intricacies, and leverages AI and automation to exceed expectations.
As an L3 Lead Solutions Engineer, you will serve as a trusted advisor to both our customers and sales teams - spearheading technical strategies in deals ranging from six to seven figures, overseeing solution design, and setting a benchmark for SE excellence through your contributions.
Our Role as Solutions Engineers
We are technical sales professionals dedicated to driving revenue by securing complex Enterprise agreements. Our mission is to lead the technical win—cultivating champions, demonstrating value, and ensuring prospects choose Klaviyo over competitors. We collaborate directly with clients to design solutions that seamlessly integrate into their technology ecosystems, employing a consultant-first approach that fosters confidence and ensures technical alignment.
Beyond closing deals, we leverage customer interactions as opportunities to prototype and deliver enhancements to Klaviyo. Recent projects include AI-driven demo data generators, a public Chrome extension for troubleshooting API calls, web SDK injectors, and templated mobile applications that highlight our SDK capabilities.
If you are a creator motivated by winning high-stakes contracts and innovative technical solutions, we want to hear from you!
