We’re building the full‑stack foundation for the next generation of humanoid robots — from high-performance, software‑defined hardware to the foundational models and video world models that control it. Our robots are designed to be generalists capable of operating in complex, real‑world environments and handling scenarios unseen in training. We work at the intersection of large‑scale learning, robotics, and systems, with a research team that includes researchers from Stanford, Berkeley, Harvard, and beyond.

We’re not building a feature; we’re building a new computing platform for physical work — and with over $400M raised, we’re investing aggressively in the R&D, hardware development, and manufacturing scale‑up to make that a reality.

We’re looking for a Full Stack Software Engineer to help build the internal platforms and tooling that power our research, robotics, and infrastructure teams. You’ll work across a broad surface area — from frontend interfaces for data collection and model validation, to backend services and APIs that tie together our cloud infrastructure, robot fleet, and data pipelines.

• The platform you build is the operating system for how our researchers and engineers work — your tools directly influence how fast we can iterate on model quality and robot behavior
• Rare opportunity to build internal tooling at the intersection of physical AI and large‑scale robotics, with direct visibility into how foundation models get developed and deployed
• High ownership in a small team — you’ll make real product decisions, not execute design specs handed down from above

• Build frontend interfaces for data collection, labeling, model validation, and experiment tracking
• Design and maintain backend services and APIs that support fast‑moving research and engineering workflows across cloud, robot, and data infrastructure
• Build tooling and dashboards for observability across cloud infrastructure, distributed training jobs, and robot fleet status
• Integrate with data infrastructure systems — storage backends, pipeline orchestration, and dataset management tools
• Build interfaces and services that connect with our physical robot ecosystem — fleet management, teleoperation, and deployment tooling
• Own reliability, performance, and scalability of internal platform tooling as usage and complexity grow
• Collaborate closely with researchers, ML engineers, and robotics teams to understand needs and ship tools that accelerate their work

• 3+ years of experience in full stack development, ideally with internal tool or platform experience
• Strong proficiency in a frontend framework (React, Vue, or similar)
• Solid backend experience in one or more languages (Python, Node.js, Go, etc.)
• Experience with cloud infrastructure and storage (e.g., AWS, GCP, S3, GCS) and backend services
• Ability to design and work with APIs (REST or gRPC) and structured data pipelines
• Comfort working across codebases and systems owned by different teams — robotics, ML, and infrastructure
• Strong attention to security, privacy, and multi‑tenant data isolation

• Familiarity with ML training pipelines, model versioning, or experiment tracking tools
• Exposure to robot fleet management, robotics control systems, or…
