Background
Klaviyo operates a real-time data analytics platform coded primarily in Python that is built for massive scale and hosted on Amazon Web Services (AWS). Engineers come to Klaviyo with experience in a variety of languages and from a number of disciplines.
Klaviyo’s Core Data Platform consists of 3 key entities: Profiles (our customer’s customer), Objects (ex: Products & Custom), and Events (the actions taken). Events are the backbone of Klaviyo. Most of our customers view Klaviyo through the lens of events. Events are key to our real time automations, insights and emerging AI feature set.
At Klaviyo, we love tackling tough engineering problems and look for employees who specialize in certain areas but are passionate about building, owning & scaling features end to end from scratch and breaking through any obstacle or technical challenge in their way. We push each other to move out of our comfort zone, learn new technologies, and work hard to ensure each day is better than the last. Klaviyo is growing fast and we have openings for all skill levels across all of our teams. Learn more about our engineering culture at https://klaviyo.tech.
