Senior🎓
Top SchoolYariv Hashai is a Senior Engineering Manager with over a decade of experience building and scaling cloud-native, real-time data and security platforms from Israel. He has led cross-functional teams to deliver multi-tenant microservices, streaming feature stores, and sub-minute SLA event systems using technologies like Flink, Spark, Kafka, Kubernetes, and Databricks. Yariv combines hands-on engineering—spanning embedded audio-reactive IoT work on popular open-source projects like WLED—to strategic architecture and cost-saving operational initiatives that delivered measurable ARR and COGS improvements. He excels at turning legacy monoliths into resilient microservices, coordinating large-scale rollouts across regions, and designing observability and CI/CD pipelines that keep services robust under pressure. Known for hiring and mentoring distributed teams, he values technical rigor, clear internal documentation, and a culture that tolerates mistakes as a path to learning. Practical, curious, and people-focused, he blends deep systems knowledge with a knack for making complex platforms configurable and customer-facing.
