• Work on speech‑to‑text and text‑to‑speech integration
• Handle dropped calls and poor connections gracefully
• Add monitoring and tests for the call pipeline

What We’re Looking For

• 3+ years building production software
• Experience with real‑time audio or telephony (WebRTC, SIP, Twilio or similar)
• Clean, maintainable, tested code
• Excellent written communication and async collaboration skills

• Experience with TTS/STT systems
• Experience building conversational or voice‑driven products
