Braze

Braze operates a customer engagement platform that enables brands to orchestrate personalized messaging across push notifications, email, SMS, in-app messages, and emerging channels using real-time behavioral data and segmentation. The company's engineering challenges include processing billions of user events per day to trigger time-sensitive campaigns, building a real-time streaming architecture that evaluates complex audience rules with sub-second latency, and maintaining delivery reliability across multiple messaging channels with varying throughput characteristics. Their platform must handle extreme traffic spikes during events like Black Friday while maintaining the personalization accuracy that drives measurable business outcomes. Braze's hiring patterns signal sustained demand for engineers skilled in high-throughput event processing, distributed systems, and the infrastructure required to deliver marketing technology at enterprise scale.
