Senior Backend Software Engineer

Hiya makes phone calls trustworthy again. We do caller ID, spam and scam protection, and branded calling for carriers, phone makers, and businesses. I run the Communications Platform team (Seattle + Barcelona). We're building new systems where telephony meets AI: real-time scam detection on live calls, deepfake voice detection, speaker verification, and AI call screening that plugs into carrier networks. Most of it is new work, so you'll help make early architecture decisions. Stack: TypeScript/Node.js, SIP/RTP, STT/TTS, Docker, Kubernetes, AWS, Terraform, Helm. Looking for 3+ years of backend experience, strong TypeScript or Python, and comfort with APIs and event-driven systems. VoIP/telephony experience is a big plus but not required. I came to telecom from a software background too. Apply: https://jobs.ashbyhq.com/hiya/2de4d41b-a919-48c4-9a6c-e0d4f3...
