Principal Software Engineer – Robot Applications & Voice AI
Location : California Bay area
Humanoid robots become truly useful when they understand human intent and convert it into meaningful action. At Cerence, we are building the cognitive and application layer that combines Voice AI, Agentic AI, multimodal reasoning, and robotic capabilities into intuitive human-robot experiences.
Role Overview
The Principal Software Engineer drives the application and cognitive layer of our humanoid robot. Working directly with the core robotics platform designed by our Architect, you will turn human intent into high-level physical actions. This role focuses on building advanced voice applications, multi-modal context systems, and programming the core business logic and behavior trees that make the robot interactive, helpful, and intuitive.
Your Impact
Build software powering the next generation of intelligent humanoid robots.
Work on Voice AI, Agentic AI, LLMs, VLMs, and Physical AI products.
Collaborate with experts in robotics, conversational AI, embedded systems, and cloud computing.
