Full job description

Responsibilities:

Design, develop, and operate real-time audio processing pipelines for conversational voice agents.

Build and maintain backend services using Python (FastAPI/async frameworks) and Node.js for low-latency workflows.

Implement bi-directional audio streaming using WebSockets, WebRTC, or similar protocols.

Integrate and optimize Speech-to-Text (STT) and Text-to-Speech (TTS) engines (cloud-based or self-hosted).

Build and maintain telephony integrations (inbound/outbound calling, call routing, call recording, DTMF, conferencing).

Optimize audio latency, jitter, and reliability across distributed systems.

Handle high-concurrency workloads and real-time session state management.

Implement monitoring, logging, and alerting for voice pipelines and call flows.

Collaborate with AI/LLM teams to integrate speech pipelines with conversational logic.

Own production deployments, on-call rotations, and incident response for voice systems.

Requirements:

4+ years of backend engineering experience, with a strong focus on real-time systems.

Strong hands-on experience with Python and Node.js in production environments.

Proven experience building real-time audio or voice applications.

Deep understanding of STT and TTS pipelines, audio codecs, and streaming concepts.

Solid experience integrating telephony platforms (inbound/outbound calls, SIP, PSTN).

Experience with WebSockets, WebRTC, or RTP-based streaming.

Strong understanding of asynchronous programming and event-driven architectures.

Experience with Docker and CI/CD pipelines.

Ability to debug and optimize distributed, latency-sensitive systems.
