WHAT YOU'LL DO

Platform Infrastructure Engineers (PIEs) are responsible for managing, maintaining, and evolving the foundational infrastructure that supports our internal Infrastructure-as-a-Service platform. PIEs specialize in building robust, scalable, and highly available systems such as Kubernetes clusters, Kafka ecosystems, and cloud environments. They apply sound engineering principles, operational discipline, and mature automation to ensure a reliable infrastructure foundation for all platform services and applications.

Our team helps to improve automation infrastructure reliability. It empowers Braze’s other engineering teams to leverage the infrastructure products and platforms we create easily. Braze operates at a massive scale with over 3.3 billion monthly active users across our customers, collecting hundreds of billions of data points each month and sending billions of messages to end-users daily. We use a diverse technology stack rooted in Ruby on Rails, MongoDB, Redis, Kafka, Kubernetes, and more.
