Python strongly preferred; JavaScript/TypeScript a plus - Deep familiarity with AI/ML APIs — you understand how to work with LLMs, speech models, and streaming APIs, and can explain tradeoffs to both engineers and executives - Demonstrated ability to run technical POCs end-to-end and drive them to a decision - Effective communicator who can bridge technical and business conversations with ease - High level of empathy and integrity in customer interactions - Thrives in ambiguity and sees constant change as opportunity, not obstacle - Bachelor's degree or higher in a technical domain BONUS QUALIFICATIONS - Experience with voice AI, TTS, STT, or real-time audio and speech systems - Ba
