My client is a stealth voice-AI startup seeking a Founding Engineer to build technology that helps people through natural voice conversations.
This is a hands-on opportunity to work directly with the founders, own development from initial prototype through to production, and shape the product, architecture and engineering culture.
Key Responsibilities
- Build and launch the company’s first voice-AI product.
- Develop conversational experiences using LLMs and speech technologies.
- Integrate speech-to-text, text-to-speech and real-time audio capabilities.
- Own development across backend services, user interfaces and infrastructure.
- Work closely with the founders to turn user needs into practical product features.
- Test and improve conversational quality, responsiveness and reliability.
- Gather user feedback and iterate, with a focus on accessibility for older adults.
