Senior Software Engineer

Hiya is hiring a Senior Software Engineer to join the Protect team, responsible for building and scaling the AI-powered spam and scam detection systems that protect hundreds of millions of people from fraudulent calls before they ring. As voice threats evolve faster than ever; driven by AI-generated abuse, sophisticated spoofing, and increasingly complex attack patterns. You'll own the end-to-end pipeline that enables our data science team to develop increasingly sophisticated scam detection models while maintaining strict privacy and regulatory compliance.

It's all about building the pipelines that allow Hiya to stay ahead of rapidly evolving voice threats and deliver measurably better protection to mobile operators and their subscribers worldwide. You'll shape how protection scales across our network, how quickly we adapt to new threats, and how effectively we translate AI innovation into real-world safety outcomes.
