Summer Internship

Software EngineeringBoston


  • Our Software Engineering internship is small, only 30-40 interns. This is purposeful - so we can ensure each intern has meaningful and robust projects that directly impact our product and customers. It also creates a tight-knit group of interns who get to bond with each other over the course of the summer. 
  • Interns are valued members of our engineering department, which is made up of small, agile teams that collaborate across Klaviyo to constantly ship work that impacts our product. Interns have ownership over features, while also learning from and connecting with fellow Klaviyos from engineering, product, design, and beyond to make sure they craft the right solutions. We operate a real-time data platform coded in Python built for massive scale on Amazon Web Services (AWS). 
  • We move fast here - interns work on projects at scale and often ship their work during the course of the summer. We offer a supportive environment where interns can test, fail, iterate and launch while building a solid technical foundation, awesome connections across the Klaviyo and having fun.
  • Interns come to Klaviyo with experience in a variety of coding languages, but they are all passionate about building, owning and scaling features end-to-end from scratch and breaking through any obstacle or technical challenge in their way.


  • At least one previous software engineering internship with software development experience
  • Graduating in December 2024 or May/June 2025
  • Experience with some of these technologies and languages:
  • Python, Django, Celery
  • MySQL, Cassandra, Clickhouse, RabbitMQ, Redis
  • HTML, JavaScript, LESS, Backbone.js, React

  • Enjoy working with new technologies ranging from the frontend to backend and adept at selecting the right tool for any job
  • Love digging into performance and scalability issues to drive breakthrough solutions-- whether it's a slow loading UI or too many clicks in a workflow, a database query timing out, or a queue that just won’t drain. You recognize all problems can be solved.
  • Enjoy shipping code early & often in an agile fashion, pairing with product management to craft better software by soliciting feedback from thousands of end users
  • Embrace Klaviyo’s “always learning” culture that fosters learning at every level, constantly pushing yourself to be a better engineer
