In this role, you’ll partner with senior leaders across Product, Design, and GTM to define how Klaviyo continues to lead the market in mobile messaging. You’ll shape the strategy, build the systems, and grow the teams that keep Klaviyo ahead. This role is intense and rewarding — perfect for a leader who thrives in motion, raises the bar for excellence, and finds purpose in building teams that scale impact globally.

- Architect for enterprise-scale reliability, security, and compliance across diverse global markets.
- Transform workflows by putting AI at the center, building smarter systems and ways of working from the ground up.
- You give and receive meaningful feedback, focusing on empathy, curiosity, and growth.

- You think like a product leader — connecting technical decisions to customer and business impact.
- You communicate clearly, collaborate deeply, and know how to align diverse teams around a shared goal.
- You’ve led large, distributed engineering organizations and built systems for enterprise customers 10–100x larger than today’s base.
