Sales Manager, Mid-Market
Hybrid Role Requirement:  Boston, MA (In-Office 3x/Week)  Team:  Sales – Mid-Market

About the Role
At Klaviyo, we believe every customer interaction is an opportunity to build stronger relationships. That mindset starts with our Sales team—and we're growing. Klaviyo is seeking a Mid-Market Sales Manager to lead a team of hybrid Account Executives responsible for both net-new customer acquisition and expansion within existing accounts.

Mid-Market is a critical growth segment for Klaviyo and plays an important role in our continued move upmarket. The team operates across a wide range of deal types, from high-velocity run-rate opportunities to larger, more complex multi-product deals. Success in this role requires strong judgment, prioritization, and execution discipline.

This role is for leaders who consistently raise the bar on talent, execution, and accountability. You will be expected to make clear tradeoffs across velocity and complexity, coach to root causes rather than symptoms, and hold yourself and your team to measurable performance standards. The impact of this role is highly visible, and success depends on ownership, clarity, and comfort operating without ambiguity.
