  • Lead strategic account planning, white space prioritization, and business review cadences to uncover growth opportunities and strengthen long-term partnerships.
  • Partner cross-functionally to define processes, rules of engagement, and operating motions that improve the Enterprise customer experience and enable your team to perform at a high level.
  • Remove roadblocks, improve team operations, and create an environment rooted in collaboration, accountability, learning, and inclusion.
  • Transform workflows by putting AI at the center, building smarter systems and ways of working from the ground up.
Who you are
  • You have strong experience in enterprise customer management, with a track record of leading through complexity and driving measurable customer outcomes.
  • 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 are an experienced people leader who knows how to coach individual contributors, set a high bar for performance, and build productive teams.
  • You have demonstrated success managing complex customer relationships and driving retention, customer satisfaction, and expansion.
  • You bring strong business acumen and can translate customer goals into clear plans, value-based conversations, and outcome-oriented execution.
  • You are highly analytical and comfortable using data to identify trends, assess performance, and inform decisions.
  • You are an excellent communicator who can engage effectively with stakeholders at all levels, including senior customer decision-makers and internal cross-functional partners.
  • You are comfortable navigating ambiguity, handling escalations, and solving problems in a thoughtful, customer-centric way.
  • You have experience with customer success and CRM tooling such as Salesforce and Gainsight; experience in SaaS and Martech is strongly preferred.

Klaviyo Compensation & Benefits Highlights

How does Klaviyo ensure its pay and bonus plans are competitive?

Klaviyo supports competitive pay through a total rewards approach that combines salary, equity, bonus opportunities, benefits, learning support and a performance culture tied to measurable impact. 

  • Competitive total rewards: Klaviyo’s benefits overview highlights competitive salaries, 401(k) match, employee referral bonuses, equity, an employee stock purchase plan, flexible paid time off, commuter/transit support, fitness reimbursements, mental and emotional wellbeing programming and learning support. External reviews reinforce the value of the package, with employees citing competitive pay, bonuses, RSUs, ESPP, health insurance, parental leave, unlimited PTO and learning stipends as meaningful parts of the employee experience.
  • Pay connected to impact and outcomes: Klaviyo’s handbook frames performance around ownership, clarity and measurable results. The value “Know the score” states that results matter more than effort alone, while “Drivers wanted” emphasizes proactive ownership and “Be meticulous in your craft” reinforces a high bar for work quality. That creates a compensation and recognition philosophy where strong outcomes, not just activity, are central to advancement and rewards.
  • Equity and long-term value: Equity is a visible part of Klaviyo’s rewards story. Klaviyo offers equity packages to all full-time employees, vesting over four years, and provides an employee stock purchase plan. That ownership opportunity sits within a growing business: in Q1 2026, Klaviyo reported $358 million in revenue, up 28% year over year, and raised full-year 2026 revenue guidance to $1.514 billion to $1.522 billion. Those business results give employees a clear connection between company performance, long-term growth and the value of ownership-based compensation.
  • Rewards supported by growth and development benefits: Klaviyo’s compensation package is paired with benefits that help employees grow their careers and build long-term value. K-Pro Learn, learning stipends, mentorship, Career Architecture and manager development programs support continued skill-building. A customer success manager noted that Klaviyo offers a learning stipend for job-related coaching or training, while employee survey insights show 78% of respondents feel they are gaining the skills and experience to grow their careers.
  • External signals:
    • Compensation Sentiment: External reviews frequently praise Klaviyo’s competitive salary, bonuses, equity, RSUs, ESPP, 401(k) match, learning stipend and generous benefits. (Glassdoor; Comparably)
    • Rewards Ratings: Comparably rates Klaviyo’s compensation an A and perks and benefits an A. (Comparably)
    • Employee Value Signals: Reviews highlight PTO, health insurance, parental leave, office amenities, learning support and work-life balance as part of the overall rewards package. (Glassdoor; Comparably)

Bottom line: Klaviyo keeps compensation competitive by combining salary, bonus opportunities, equity, ESPP, retirement support, benefits and learning resources with a culture that rewards ownership, measurable outcomes and long-term impact.
