The stack (Scala, Kafka, Kubernetes, Spark, DynamoDB, Redshift) reflects a data-intensive, real-time signal-processing architecture; the hiring surge across engineering and sales with senior-level roles indicates scaling both product depth (AI-powered detection systems) and go-to-market velocity, while active projects span phone-call processing pipelines and multi-year strategic customer initiatives.

About Hiya Inc.

Hiya provides a Voice Intelligence Platform serving three customer segments: enterprises using Branded Call to display company identity and reduce customer skepticism, carriers and OEMs integrating spam/fraud protection into their networks, and indirect users (500M+ consumers) protected by the platform's detection layer. Founded in 2016 and headquartered in Seattle, the 51–200-person company operates across the United States, United Kingdom, Hungary, Germany, and France. Core offerings address two persistent problems: AI-generated spam increasingly eroding telecom trust, and missed legitimate conversations due to overly aggressive call-blocking. The product ingests and processes call signals in real-time, applies machine-learning-based detection, and surfaces branded call metadata to end users.
