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. Required Skills & Experience Mandatory (Must Have) 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. Good to Have (Highly Valued Plus) Robotics Framework Consumption: ROS2 application nodes, Services, Actions, Topics, navigation and manipulation APIs. Vision & Multi-Modal AI: Object detection, scene understanding, visual grounding, and spatial reasoning systems. Audio Hardware Integration: Beamforming, Acoustic Echo Cancellation (AEC), microphone arrays, and noise suppression. Physical AI Applications: Experience building software for humanoids, service robots, warehouse automation, or embodied AI systems. Data & Learning Pipelines: Telemetry, analytics, evaluation systems, retraining pipelines, and AI feedback loops. Containerization & Deployment: Docker, Kubernetes, OTA updates, and edge deployment environments. Startup Environment: Comfortable owning solutions from concept through deployment in a fast-moving environment.
