Hybrid Role Requirement: London, United Kingdom (In-Office 3x/Week)

Team: Sales – Mid-Enterprise

We’re looking for a Mid-Enterprise Account Executive to join our tenured, high-performing team selling into some of the world’s most recognizable brands. This is more than just closing deals. It’s an opportunity to shape the future of our upmarket business by bringing Klaviyo to customers who are reimagining their marketing tech stack.

From first touch to signed agreement, you’ll own the full sales cycle—partnering closely with teams across Solutions, Customer Success, Product, and Engineering to drive long-term value for our customers. You’ll be selling to companies like Birkenstock, Represent, Castore, and Dishoom. It’s a big responsibility—and a bigger opportunity.

Transform workflows by putting AI at the center, building smarter systems and ways of working from the ground up. Continuously experiment with AI tools—testing, learning, and sharing insights to keep the team and organization ahead of the curve, as well as championing new applications that accelerate workflows and elevate quality responsibly. Apply AI fluency to streamline work, reallocate saved time and reinvest into more meaningful, high-impact areas.

Responsibilities:

• Build and grow Klaviyo’s Mid-Market and Enterprise client base
• Drive full-cycle sales efforts: prospecting, discovery, demo, negotiation, and close
• Create and execute territory and account strategies for long-term growth
• Partner cross-functionally with Solutions Architects, Customer Success, and Marketing to deliver a world-class buying experience
• Provide mentorship and leadership across the AE team
• Share market insights with Product and Engineering to influence roadmap decisions

Who You Are / Required Experience:

• You’ve already experimented with AI in work or personal projects, and you’re excited to dive in and learn fast.
• You’re hungry to responsibly explore new AI tools and workflows, finding ways to make your work smarter and more efficient.
• You use AI tools to accelerate exploration, shorten iteration cycles, and bring sharper ideas to the table.
• As part of your craft, you’re curious, adaptable, and eager to deepen your fluency in AI (understanding capabilities, limits, and risks).
• You don’t wait to be told what tool to try—you explore, test, and share what works.
• Based in London, UK and available to be in-office 3 days/week
• 6+ years of closing experience, preferably in SaaS or MarTech; experience hunting net new business from self-generated leads through negotiation and closure (closed/won); comfortable navigating strategic deals with multiple stakeholders and complex buying processes
• Experienced in technical selling—able to communicate value with clarity and confidence; knowledge of the marketing automation or CDP space is a plus
• Resilient in the face of challenges and energized by a fast-moving environment; a natural relationship-builder with strong influencing skills
• Committed to learning, sharing, and contributing to a high-trust sales culture

Klaviyo is an Equal Opportunity Employer. We’re committed to building a company that reflects the diversity of the customers we serve—and that starts with our team.
