Klaviyo Careers: Everything You Need to Know Before You Apply

If you’ve been researching marketing technology companies to work for, chances are Klaviyo has come up. As the company behind one of the fastest-growing customer data and marketing automation platforms in ecommerce, Klaviyo has built a reputation not just for its product, but for the way it hires, develops, and treats its people. This article breaks down what Klaviyo careers actually look like the company itself, the kinds of roles available, culture and benefits, and how to put your best foot forward in the application process.

What Is Klaviyo?

Klaviyo (pronounced “clay-vee-oh”) is a publicly traded company (NYSE: KVYO) known as a B2C CRM platform. It combines marketing automation, analytics, and customer service into a single system built around first-party customer data, helping brands turn everyday transactions into long-term customer relationships. Today, Klaviyo supports nearly 200,000 brands worldwide, including recognizable names like Mattel, Glossier, Daily Harvest, and Liquid Death. The platform is built around unlimited customer data and hundreds of native integrations, allowing brands to automate highly personalized email, SMS, WhatsApp, and push-notification communication without stitching together multiple disconnected tools.

Employees at Klaviyo often refer to themselves as “Klaviyos” a small detail that reflects a broader emphasis on community and shared identity within the company. The company’s name itself carries meaning: it’s inspired by clavija, a Spanish word for the pitons mountaineers use small anchors that support climbers as they ascend and catch them if they fall. It’s a fitting metaphor for a company whose product is meant to help merchants “climb” by making better use of their own data.

A Brief History

Klaviyo was founded in Boston in 2012 by Andrew Bialecki and Ed Hallen, two former colleagues from Applied Predictive Technologies who saw that consumer brands were sitting on huge amounts of customer data they couldn’t actually put to use. Rather than raise venture funding right away, the founders bootstrapped the company for its first few years, focusing on product-market fit with early e-commerce integrations on platforms like Shopify and Magento. That patient, product-first approach eventually paid off: Klaviyo grew into one of the leading customer data and marketing automation platforms in e-commerce, culminating in its IPO on the New York Stock Exchange in September 2023. Since then, the company has continued to expand its platform through acquisitions including its 2025 purchase of social media engagement platform Gatsby and by pushing further into AI-driven, agentic marketing tools.

Klaviyo is headquartered at 125 Summer Street in Boston, Massachusetts, with additional offices in cities including London, Sydney, Denver, and San Francisco, reflecting its growth into a genuinely global company with several thousand employees.

Types of Roles at Klaviyo

Klaviyo hires across a wide range of functions, and open roles typically span:

• Engineering — Software engineers work on complex, large-scale systems, from core platform infrastructure to authentication and identity management (IAM), mobile messaging channels (SMS, RCS, WhatsApp), and backend architecture.
• AI and Machine Learning — With AI now described as foundational to how Klaviyo builds and operates, ML teams work on intelligent systems trained on data from hundreds of thousands of brands and billions of customer interactions, including recommendation engines and AI-native customer agent platforms.
• Product Management — Product managers own strategy end-to-end, from vision through execution, working cross-functionally to shape the platform roadmap.
• Product Design — Designers focus on translating complex workflows into intuitive, end-to-end product experiences, often using AI tools to prototype and iterate quickly.
• Sales — Roles range from Business Development Representatives (BDRs) to Account Executives across commercial, mid-enterprise, and enterprise segments, along with sales management and enablement positions.
• Customer Success — Customer Success Managers help brands get the most out of the platform through tailored success plans, proactive check-ins, and product education.
• Marketing — From social media strategy to integrated campaign marketing, these roles blend creative and data-driven approaches to demand generation.
• People, Legal, and Operations — Klaviyo also hires for internal functions like People Technology, compliance, security, and business operations that keep the company running as it scales.

A recurring theme across nearly every job description is AI fluency. Klaviyo explicitly frames itself as an “AI-first” company, and many roles even outside of engineering now expect comfort using AI tools to work more efficiently.

Internships and Early-Career Programs

Klaviyo runs paid internship and co-op programs for students and early-career candidates interested in software engineering, machine learning, sales, marketing, product design, or finance. These programs come with mentorship, stipends, and resources designed to help participants build real skills rather than just observe from the sidelines a common complaint about internships elsewhere.

Where Klaviyo Hires

While Boston remains Klaviyo’s home base, the company hires across a distributed network of regional hubs rather than concentrating all roles in one city. In addition to its Boston headquarters, Klaviyo maintains offices in London, Sydney, Denver, and San Francisco, and many job listings note hybrid or remote flexibility depending on team and location. This means candidates outside of Boston shouldn’t assume Klaviyo careers are out of reach plenty of engineering, sales, and customer success roles are based in or open to other regions, particularly as the company continues its push into EMEA and APAC markets.

What the Interview Process Looks Like

Like most fast-growing tech companies, Klaviyo’s interview process typically involves multiple stages: an initial recruiter screen, one or more conversations with the hiring manager and future teammates, and role-specific assessments technical exercises for engineering roles, case studies or mock pitches for sales and customer-facing positions, and portfolio reviews for design roles.

One detail worth knowing ahead of time: Klaviyo has published specific guidelines governing how candidates may use AI tools during the interview process itself. Given that the company treats AI fluency as a core job expectation, it’s reasonable to expect that interviews may probe how thoughtfully and responsibly a candidate uses AI not just whether they use it at all. Reviewing Klaviyo’s official guidance before your interview is worth the ten minutes it takes, so you’re not caught off guard by an unfamiliar policy.

Culture and Values

Klaviyo describes its ideal work environment as one built for people who want ownership, thrive on feedback, and are motivated by meaningful challenges. The company emphasizes:

• Ownership and autonomy — Teams are increasingly designed to be “autonomous first,” with individuals expected to drive outcomes rather than wait for direction.
• Inclusion by design — Klaviyo states that inclusion is intentionally woven into how it builds teams and serves a diverse global customer base, rather than treated as a side initiative.
• High standards, real impact — The company is candid that the work is demanding. Its own careers messaging notes that powering digital experiences for major B2C brands “isn’t easy and it’s not meant to be,” positioning the difficulty as part of the appeal for people who want accelerated growth.
• Distributed, global teams — Klaviyo operates across regional hubs around the world, with many roles supporting hybrid or remote work arrangements depending on location and function.

Compensation and Benefits

Klaviyo positions its benefits around the idea that growth shouldn’t stop when the workday ends. Reported offerings include:

• Lifestyle spending accounts for health and personal goals
• Career development resources and mentorship
• Competitive pay, with third-party salary data suggesting, for example, median total pay around six figures for roles like Customer Success Manager and Product Expert
• Support structures aimed at overall wellbeing, not just workplace perks

As with any company, exact benefits vary by role, level, and location, so it’s worth confirming specifics during the interview process.

How Employees Rate Career Growth

Independent review platforms give some insight into the employee experience. According to recent Glassdoor data, Klaviyo employees rate their career development opportunities at roughly 3.3 out of 5 stars based on hundreds of anonymous reviews a reasonable, if not glowing, signal that’s worth weighing alongside the company’s own messaging about growth and ownership.
