At Klaviyo, we're building the platform that helps businesses create and deliver personalized customer experiences at scale, powered by first-party data.
We’re looking for a Senior Product Designer to join the Design System team and help evolve Ascent, Klaviyo’s design system. You'll define and scale the reusable components, patterns, tokens, documentation, and standards that help teams ship faster, creating a more consistent and usable product experience across Klaviyo.
This role sits at the intersection of product design, engineering, and systems thinking. You'll partner across product teams to improve design-to-code parity, drive adoption, and use AI and automation to reduce manual friction while maintaining a high bar for quality, accessibility, and system integrity.
- Evolve Ascent's components, patterns, tokens, interaction standards, and documentation across Klaviyo's product surfaces.
- Partner with engineering to improve design-to-code parity and ensure coded components reflect design intent.
- Identify inconsistencies, gaps, and duplicated patterns across product teams, then turn them into scalable system improvements.
- Own the end-to-end design process from conceptualization to discovery, and in some cases all the way to implementation.
- Support adoption through clear guidance, design critiques, spec reviews, office hours, workshops, and release communications.
- Use AI and automation to accelerate prototyping, documentation, design specs, accessibility checks, visual QA, and system maintenance.
- Strong product design experience with a portfolio that shows high-quality UX, interaction, and visual design craft.
- Experience building, maintaining, or scaling a design system within a complex product organization.
- Strong systems thinking, with the ability to spot patterns, simplify complexity, and design for reuse across large product surfaces.
- Working knowledge of design tokens, accessibility standards such as WCAG, and how system decisions map to frontend implementation.
- Ability to partner deeply with engineers, PMs, brand designers, writers, and stakeholders to align teams without relying on authority.
- AI-first builder mindset, using tools like Claude, Cursor, v0, Figma Make or similar to explore ideas, prototype, generate code, and improve system workflows.
- Experience with Storybook, code-level component documentation, Git, or design system release workflows.
- Experience with complex, data-rich SaaS products.
- Expertise in Figma component architecture, variables, styles, libraries, and scalable design workf

What the Team is Saying
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)
