About Us

A San Francisco based startup building next-generation Voice AI products that redefine how humans interact with machines  from smart voice assistants to automated customer conversations, voice-driven tools, and more.

We are at the intersection of speech technology, large language models, and real-time systems, backed by leading investors and supported by domain experts. We’re now building our founding engineering team in India to shape the core product experience.

What You'll Do

• Build and deploy real-time voice-based AI applications using ASR (Automatic Speech Recognition), TTS (Text-to-Speech), and LLMs.
• Work on latency-sensitive systems to enable near real-time conversations.
• Design and implement prompt-chaining, memory, and tool integration for LLM-powered voice agents.
• Set up and manage scalable infra for voice/audio processing and AI model serving.
• Work closely with the founding team on product shaping, roadmap planning, and technical strategy.
• Continuously experiment with and evaluate new models, APIs, and speech/LLM techniques.

Who You Are

• 3-8 years of experience in AI/ML, deep learning, or backend-heavy engineering roles.
• Solid hands-on experience with speech technologies (ASR, TTS, diarization, etc.).
• Comfortable working with Python, PyTorch, Hugging Face, OpenAI, or similar frameworks.
• Experience deploying real-time systems (Docker, Kubernetes, AWS/GCP).
• Strong problem-solving skills with a product-first mindset.
• Self-starter who thrives in high-ownership, fast-paced environments.
• Excellent written and verbal communication
