Have documented commercial experience building production real-time audio pipelines; batch transcription, offline STT, or basic RAG experience alone is insufficient.
Have practical knowledge of at least two streaming components among STT, MT, and TTS.
Have experience with tools such as Pipecat, LiveKit, Vapi, or custom Python orchestration layers.
Have production experience with WebRTC, including audio transport behavior under degraded network conditions.
Have experience instrumenting and measuring latency on real mobile devices, including p95 percentiles and tail behavior.
Have experience selecting AI providers that meet strict data-protection requirements, including EU hosting and zero data retention.
Have spoken and written English at a minimum C1 level for technical discussions and documentation.
Clearly show real-time audio or voice-pipeline experience on the CV.
Nice to have: React Native and native audio modules in Swift or Kotlin.
Nice to have: Bluetooth audio experience on iOS or Android.
Nice to have: on-device AI inference or voice cloning / speaker similarity experience.

Develop and verify per-component latency budgets across VAD, transport, STT, MT, TTS, jitter buffering, and playback.
Evaluate STT, MT, and TTS providers for streaming support, EU data residency, and zero data retention.
Design an automated AI-to-AI call evaluation framework and define quality gates based on p95 measurements on physical devices.
Prepare the repository foundation, CI/CD, and starting architecture for the Alpha build.
Work directly with the client’s Fractional CTO in architecture discussions and defend technology decisions.
Create clear architecture specifications and reports in English.
