Zinnia operates a technology platform for life and annuity insurance carriers and distributors, built on a polyglot cloud-native stack (Kubernetes, gRPC, GraphQL, AWS Lambda, NestJS, React, Java, Python, Go) with strong CIAM and API governance patterns. The company is actively adopting RAG and scaling product operations through a large engineering cohort, while addressing regulatory alignment and suspicious-activity detection—typical for financial services infrastructure. The senior-heavy hiring profile and enterprise API focus suggest they're consolidating internal tooling and preparing for scaled distribution.
