• Our Summer Internship Program is an 11-week paid experience [June 1–August 13] at our Boston, MA headquarters. Interns are in office 5 days a week.
• Offers will be team agnostic - interns are placed on a team approximately 30 days from the start of the program. Team placement can be on a full-stack, back-end, or front-end team within any of the pillars.
• Before joining individual teams, all interns go through Klaviyo Base Camp, our onboarding experience built to get you up to speed on Klaviyo, our product, and the day-to-day of engineering here, plus time to get to know the other interns. You'll join your team ready to dive into real project work from day one.
• Our Boston office is genuinely fun. Lunch is on us 5 days a week, along with free snacks and drinks, ping pong, Nintendo Switch, a golf simulator, and a speakeasy to unwind in.
• Throughout the summer, interns get together for social events beyond team and project work: a Red Sox game, a Boston Harbor Cruise, trips to Kings and Versus, ice cream socials, and Ask Me Anything sessions with Klaviyo's senior leadership.
• Apply before October 11 if you can. We interview and hire on a rolling basis.
