About the Team

Our engineers are organized into a series of product pillars, where multiple teams are contributing to the goals of a larger mission. This role sits within the Intelligence pillar which focuses on two main goals: helping customers understand where their business is currently, as well as helping them predict and plan for where they want to grow in the future. 

The Product Merchandising team powers one of the most important data science functionalities at Klaviyo: the dynamic product block. We’re starting to explore a variety of additional ways to leverage the data in our product catalog integrations to enable our customers to learn and act on more signals coming through their catalog performance. We are currently working to increase the throughput of product recommendations, which requires significant re-architecting of portions of the system.

We are proud of our data and our goal is to harness that wealth of numbers and present them to our customers in a way that is actionable, intuitive, and accessible. In the Intelligence pillar, software engineers and data scientists work together to take ideas from inception to new machine learning-powered features.

About the Role:

As an Engineering Manager for our Product Merchandising team, you will be responsible for people management of all engineering team members within that group. You will work hand-in-hand with the Technical Product Owner and Product Manager to set the technical priorities and roadmap, and will be primarily responsible for ensuring the pace and quality of technical execution. You will help the team grow both as individuals and as a team by sharing and encouraging the adoption of best practices, both from a team process perspective as well as from a technical approach perspective. We’re looking for someone who is passionate about developing others to help foster each person’s growth and level up technical skills.

In addition, the Product Merchandising team interacts with several other areas of the product such as the commerce service that houses our catalog data and the templates team that renders product recommendations. The new EM will be critical in coordinating the technical execution of all of these cross-company projects.

  • Build data pipelines that ingest and process billions of customer events
  • Collaborate with data scientists to deploy machine learning solutions powered by billions of customer events
  • Deploy features that help more than a hundred thousand companies communicate effectively with their customers and grow their business
