Principal Software Engineer - Robot Applications & Voice AI

Role Description

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.
• See your work deployed in real-world robotic environments.

Key Responsibilities

• Application Layer & Business Logic: Implement high-level application software, interaction workflows, and robotic behavioral state machines.
• Intent-to-Action Orchestration: Build the core logic that translates human speech, gestures, environmental cues, and contextual information into deterministic robotic tasks.
• Multi-Modal Interaction Fusion: Integrate vision pipelines, object detection, scene understanding, spatial tracking, and voice interactions to provide contextual awareness.
• Voice Application Engineering: Develop robust voice applications managing STT, NLU, dialog management, wake-word detection, and TTS interfaces.
• Agentic AI Development: Build orchestration workflows combining LLMs, VLMs, memory systems, tool calling, reasoning engines, and robotic capabilities.
• Robot Capability Integration: Consume and orchestrate navigation, manipulation, perception, and device-control services exposed by the robotics platform.
• Edge/Cloud Partitioning: Optimize applications to balance low-latency local execution with cloud-based AI services.
• Multi-Device & Ecosystem Integrations: Integrate robots with mobile devices, smart home ecosystems, enterprise applications, and cloud APIs.
• Data Loop Contribution: Build telemetry, logging, and evaluation mechanisms supporting continuous model improvement.
• Deployment & Production Readiness: Contribute to testing, observability, CI/CD, and production deployment practices.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Robotics, Software Engineering, AI, or a related discipline.

Requirements

• Orchestration & Logic Frameworks: Strong proficiency in BehaviorTree.CPP, state machines, workflow orchestration engines, or task-planning architectures.
• Cognitive AI & Agent Systems: Hands-on experience building applications using LLMs, VLMs, tool-calling architectures, agent frameworks, RAG systems, or semantic memory platforms.
• Programming: 5+ years of professional software engineering experience using Python and/or C++.
• Application Architecture: Experience designing scalable application-layer software, API-driven systems, distributed services, and event-driven architectures.
• Edge Compute Management: Experience optimizing software on resource-constrained edge hardware under intermittent connectivity conditions.
• Cloud & AI Services: Experience integrating cloud AI services, model serving platforms, and containerized deployments.
• Software Quality & Production Delivery: Automated testing, debugging, monitoring, observability, and CI/CD practices.
• Human-Robot Interaction Mindset: Experience designing natural, context-aware human-machine experiences.

Benefits

• Salary range $165,550.00 USD- $264,450.00 USD.
• Annual bonus opportunity.
• Insurance coverage (medical, dental, vision, life, and disability).
• Paid time off.
• Paid holidays.
• Company contribution to the RRSP (Registered Retirement Savings Plan).
• Equity awards for certain positions and levels.
• Remote and/or hybrid work available depending on the position.
