Senior Software Developer – Real-Time Voice AI | Remote (US/Canada – ET or PT hours)

Build Tech That Could Save Lives

Client is transforming emergency response with cutting-edge AI. Our mission? Eliminate 911 delays by equipping emergency services with intelligent voice agents that handle routine tasks — so dispatchers can focus on saving lives.

We’re not building just another SaaS product. We’re building mission-critical systems that impact real people, in real time.

What You’ll Be Doing

You’ll be a key engineer in our fast-growing team, driving innovation at the crossroads of AI, voice tech, and real-time systems:

* Build and iterate on voice-first AI features that redefine how emergency calls are handled
* Design and scale infrastructure to meet strict reliability and performance standards
* Own features across the stack — backend services, frontend interfaces, and everything in between
* Optimize audio processing (STT, TTS, VAD, noise filtering, etc.) for real-time response
* Integrate LLMs like OpenAI, Cohere, or Anthropic into powerful voice workflows
* Collaborate directly with founders and help set our technical vision
* Grow into a mentorship/leadership role as the team scales

You’ll Succeed If You Have...

* Experience in real-time/concurrent programming (Elixir, Go, or similar)
* Deep familiarity with PostgreSQL and scalable backend systems
* Hands-on work with voice/audio processing
* Comfort with AI tools/LLMs (LangChain, OpenAI, etc.)
* Experience with Docker/Kubernetes and public cloud (AWS, Azure, or GCP)
* A mindset for building robust, fail-safe systems

Bonus Points For:

* Python or Node.js/TypeScript experience
* Knowledge of telephony protocols (PSTN, SIP, PBX)
* Familiarity with WebRTC or vector databases (Pinecone, Qdrant)
* Previous work on mission-critical or real-time applications

Why Join Client?

* Build tech that directly improves public safety
* Join a small, elite team with big technical ownership
* Work remotely with flexibility and autonomy
* Influence the future of AI in emergency response
