Sr. Solutions Engineer, Mid- Enterprise

Klaviyo•San Francisco, CA

About The Position

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
