K–12 learning platform serving a third of US elementary and middle schools
Curriculum Associates operates i-Ready, a diagnostic and instructional platform embedded in roughly one-third of K–8 classrooms nationwide. The tech stack is Java/Scala-heavy on the backend (Kafka, Spark, AWS EMR for data processing) with React/TypeScript on the frontend, now adopting Snowflake, Databricks, and Azure—a shift toward centralized cloud analytics and ML infrastructure that suggests deepening data science capability. Hiring remains engineering-forward (24 engineering roles vs. 8 sales), with active projects spanning district adoption campaigns, performance dashboarding, and synthetic load testing, indicating infrastructure scaling and product consolidation work.
