Team Overview:
The Asynchronous Processing team is dedicated to designing, developing, and maintaining Klaviyo’s robust event-driven architecture. Our goal is to provide the tools necessary for every product team to manage data seamlessly, regardless of volume. Utilizing technologies such as Golang, Python, Apache Pulsar, Kafka, SQS, AWS, and Kubernetes, we deliver self-service platforms for queuing and background processing, allowing engineering teams to prioritize customer impact while we ensure their operations are efficient, observable, and resilient.
