The best company culture and community one could hope for to address challenging problems in the industry

Software Engineer • Current Employee

October 13, 2022

Pros: One of the few places where I truly felt comfortable learning and excited to solve challenging infrastructure problems. There is no knowledge hierarchy and it truly feels like you can ask a question to anyone at anytime.

Cons: It is a heavily hybrid company, so it is not always easy to meet your coworkers in person, which would be nice. The company does make it a point to have onsites every now and then, though.

AI first = nail on Klaviyo coffin

Site Reliability Engineer • Current Employee

September 16, 2025

Pros: Work is easy and benefits are ok.

Cons: AI first initiative is making everyone lazy and less competent. SRE department head was fired due to office politics. Anyone with actual internal domain knowledge was either laid off or left the company. You will be on call every other week due to attrition and inability to hire new talent, most likely due to low compensation packages. Oh, and the company is experimenting with a hiring freeze until at least the end of 2026. Yikes.
