Job description

Job Description Real-Time Audio Systems Engineer (Real-Time Browser Audio)

We are seeking a highly skilled Real-Time Audio Systems Engineer with strong expertise in browser-based audio streaming, WebSockets, and real-time voice bot architecture. The ideal candidate will design and implement low‑latency, full‑duplex audio pipelines that run directly in the browser and integrate with modern STT, LLM, and TTS systems.

Responsibilities

• Build real‑time browser audio clients using Web Audio API, MediaRecorder, AudioContext, AudioWorklets, and WebSockets.

• Implement bi‑directional audio streaming (microphone backend speaker) with <500ms latency targets.

• Integrate streaming STT (AssemblyAI, OpenAI Realtime, Transcribe, or similar).

• Implement streaming TTS playback, including chunked audio decoding and buffered playback.

• Develop backend streaming servers (Node.js/Python) for handling audio frames, STT events, LLM routing, and TTS responses.

• Build and optimize wake‑word workflows and VAD (voice activity detection).

• Handle audio formats & codecs (PCM, Opus, WAV) and real‑time transcoding.

• Ensure reliability: reconnection logic, jitter buffers, packet timing, audio frame synchronization.

Requirements такі

• Strong experience with WebSockets and browser-based real‑time audio.

• Deep understanding of Web="/">Audio API, audio buffers, sample rates, streams, and playback pipelines.

• Hands‑on experience with streaming STT/TTS and integrating LLMs.

• Proficiency in Node.js or Python for real‑time backend services.

• Knowledge of DSP basics (noise suppression, VAD), latency optimization, and audio pipeline debugging.

Nice to Have

• Experience with WebRTC audio.

• Familiarity with wake‑word engines (Picovoice, Porcupine).

• Experience building Alexa/Siri‑like conversational agents.
