Who You Are

  • You are excited to build out the UX and backend needed to bring a data science model into the hands of users.
  • You are capable of analyzing data and making rigorous statements about what can or cannot be concluded.

An Insider's view of Klaviyo

What's something quirky about your company?

The simplest way I would describe the Klaviyo office is "energy". From the minute you start your day there's an excitement that everyone is working toward the common goal of helping businesses grow. It's a pretty amazing thing to be a part of and you can really feel it.

Director of Community Management

How do you collaborate with other teams in the company?

One of the great things about working at Klaviyo is that I get to work with amazing people from across the organization. While working in Finance isn’t intuitively a role that involves a lot of collaboration - Klaviyo’s finance team has regular interactions and team syncs with Sales Ops, Customer Support and the People Team!
