Skild AI builds foundation models and control systems for robots using PyTorch, TensorFlow, JAX, and ROS 2. The stack spans simulation (Blender, Three.js, React Three Fiber), real-time telemetry (WebSockets, WebRTC), and cloud infrastructure (AWS, GCP, Azure), indicating a pipeline from training through deployment. Engineering dominates hiring (34 of 56 open roles), with heavy emphasis on senior IC roles—reflecting the research-intensive phase of training large-scale robot models. Active projects target model training infrastructure, data pipelines, and animation-to-simulation workflows; pain points cluster around scaling both data annotation and RL training, plus deploying prototypes to production reliability.
Skild AI, founded in 2023, develops general-purpose robotic intelligence. The company is structured around foundation model training (PyTorch, TensorFlow, JAX), simulation and visualization (Blender, Three.js, WebXR), and real-time robot control systems (ROS 2, embedded C++). Projects span model training pipelines, motion capture integration, humanoid animation, and fleet monitoring dashboards. The 11–50 person team is concentrated in Pittsburgh with engineering roles primarily based in the United States and India. The hiring focus on senior engineers and the emphasis on scaling training infrastructure and data annotation suggest the company is moving foundation models from research toward production deployment.
Primary languages are C++, Python, and JavaScript/TypeScript. C++ powers embedded robot control; Python handles model training (PyTorch, TensorFlow, JAX); JavaScript/TypeScript support web interfaces (React, WebSockets, WebRTC).
All three major cloud providers: AWS, GCP, and Azure. Multi-cloud adoption likely supports distributed training and failover for model infrastructure.
