About this role
Developing conversational AI agents, optimizing latency, and integrating real-time translation tools form the core daily focus for engineers on this team. RapidSOS operates a public safety intelligence platform that connects millions of devices with emergency responders worldwide. Within the Voice AI group, engineers design backend architectures, evaluation tooling, and full-stack features that help emergency services triage alerts and coordinate faster responses.
Created to expand the capabilities of emergency response technology, the position suits software engineers who enjoy building reliable, production-grade AI systems. Successful candidates typically bring a strong background in backend or full-stack engineering, a habit of using AI-assisted coding tools daily, and a careful approach to safety-sensitive software.
What you will do
- Own Voice AI agent capabilities across the entire lifecycle from discovery and experimentation to deployment and impact measurement.
- Enhance conversational quality metrics such as latency, turn-taking, barge-in, multilingual behavior, and protocol adherence.
- Design fail-safe behaviors and maintain service resilience, observability, and production incident management.
- Build and run automated evaluations, call-replay tools, and controlled traffic trials to measure system performance.
- Write Python backend code while also contributing to the TypeScript and React frontend when needed.
- Participate in a weekly on-call rotation and travel periodically for team gatherings within Europe.
What you need
