Product Designer

About the role

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 product designers to help shape that future. This role focuses on delivering polished, user-centered designs for a defined product area by improving usability, reducing friction, and helping customers move faster and make better decisions.

Designers at Klaviyo actively use AI throughout their process, from exploring ideas and generating prototypes to refining and shipping high-quality experiences. You'll partner closely with product and engineering to understand problems, iterate on ideas, and deliver meaningful outcomes.

This is a role where you'll grow your independence over time. We share work early, iterate often, and prioritize curiosity, collaboration, and craft.

What you’ll do

• Design end-to-end product experiences across Klaviyo’s platform
• Translate complex workflows into clear, intuitive, well-documented solutions
• Design AI-assisted experiences that help users create, decide, and act more effectively
• Prototype and iterate using AI tools alongside traditional design workflows
• Apply Klaviyo's design systems consistently and contribute feedback to help evolve them
• Collaborate with PM and engineering from problem definition through launch, with a focus on clear and consistent communication
• Participate in and conduct customer research and usability testing to validate ideas and connect design decisions to real user needs

What you’ll need

• Excellent design craft with strong fundamentals in visual hierarchy, interaction design, and usability.
• Ability to translate complexity into clear, polished solutions
• Experience working with design systems and applying patterns consistently across a product
• AI fluency. Actively uses tools like Claude, Cursor, v0, or similar to accelerate workflows and prototyping
• Prototyping mindset. Comfortable moving from concept to prototype to iteration, focused on learning and improving quickly
• Collaborative approach. Partners closely with product and engineering throughout the design process, shares work regularly, and communicates design rationale clearly
• Research-driven. Participates in and conducts usability testing and customer conversations to connect design decisions to real user needs and outcomes
• Adaptability. Proactively seeks out feedback, iterates quickly, and navigates evolving priorities with a positive and curious attitude

Nice to have:

• Experience with complex or data-rich products
• Familiarity with marketing, messaging, or growth platforms
