The Klaviyo Data Science team enjoys tackling real-world problems and the excitement that comes with building new features that users love. We speak directly with users so we can understand the issues they face and then build software to alleviate these problems. We love to move fast, keep learning, and get stuff done.

Klaviyo operates a real-time data platform coded in Python built for massive scale on Amazon Web Services (AWS). Engineers come to Klaviyo with experience in a variety of languages and from a number of disciplines.

The Creative Guidance Team is experimenting with ways to guide Klaviyo users and enable them to create engaging content more quickly, easily, and frequently. The team recently launched Showcase, an algorithmically selected library of high-performing email and SMS campaigns sent with Klaviyo that users can search through for creative inspiration for their next campaign. The team is actively conducting a number of experiments to help streamline and simplify the creative process. We’re also working on a subject line generator powered by GPT-3 that enables users to quickly generate subject line ideas for email campaigns.

As a Senior Software Engineer on the Creative Guidance Team, you will primarily be responsible for prototyping and testing new features that utilize NLP models like GPT-3 to generate copy for users. You will also be responsible for helping us improve and expand our Showcase product, in addition to designing and productionalizing new features with the intent of adding value to users along their creative journey. You will work directly with other engineers as well as data scientists, designers, and product managers to help shape a core part of the Klaviyo user experience.

Technologies we use (not comprehensive!):

• Python (numpy, pandas, scipy, sklearn, Django)
• React, Typescript
• GPT-3
• Amazon Web Services (ECS, EC2, RDS, Aurora, etc.)
