Job Description

We are a well-capitalized stealth startup building robotic foundation models and world models for Physical AI. Founded by researchers from leading AI labs, our team works across robot hardware, data, infrastructure, and machine learning.

We are hiring software engineers to build the systems around our robots: the data and infrastructure that our models are trained on, the tools our researchers and operators use every day, and the product our partners will eventually depend on.

We are a small team, so everyone works broadly. What differs between our engineers is where they go deep. We have three focus areas open, described below. You do not need to match all three, and you do not need to decide before you apply.

This is an implementation role rather than a research role. You will not be designing models; you will be building the systems that let us train, evaluate, and deploy them.

Qualifications

Required Qualifications

  • BS or MS in Computer Science, Software Engineering, Computer Engineering, or a related field, or equivalent practical experience.
  • Experience building and shipping production software that other people depend on.
  • Strong proficiency in Python, plus Linux and Git.
  • Experience designing and operating services, APIs, and databases in a cloud environment.
  • Experience with Cloud infrastructure e.g. AWS, GCP
  • Strong cross-stack debugging and problem-solving skills.
  • The ability to work from a described problem rather than a written specification.
  • Experience using AI coding agents such as Claude Code, Codex, or comparable tools, including reviewing and validating generated code.
  • Ownership and initiative: you find problems and solve them without waiting for direction.
  • Comfortable working in a fast-moving environment and taking ownership of ambiguous problems.

Preferred Qualifications

  • Experience with robotics, hardware, autonomous systems, or another physical-world product.
  • Familiarity with robot data collection, teleoperation, or policy evaluation workflows.
  • Familiarity with ML data pipeline and GPU training infrastructure
