Job description

We're looking for a mechanical engineer who will design the body of robots that will live in hundreds of thousands of homes. You'll own the mechanical stack end to end and move fast: sketch on Monday, printed and tested by Friday.

We are on a mission to build a new way for humans to interact with technology

Our first product Ongo , a character that lives in your space, went viral and sold out. We're now shipping the first hundreds of thousands of interactive robots into real customers homes. If you want to do robotics that actually leaves the lab, come build with us.

The team is cracked with top engineers alongside a top creative talent Alec Sokolow (Oscar-nominated writer of Toy Story).

Building Ongo is just the first step. Our hardest challenges still lie ahead. If you're excited to solve some of the world's biggest problems and build products that will shape how humans think about technology. Join us!

You will work on

• Designing, iterating, and releasing production-ready mechanical parts and mechanisms with a strong emphasis on rapid prototyping through CAD and 3D printing.
• Writing the spec for each component and choosing the right one, turning product needs into measurable requirements, benchmarking options, and locking in the best fit.
• Managing tolerances and maintaining alignment across CAD models, BOMs, drawings, GD&T, and assembly instructions throughout the design lifecycle.
• Conducting detailed analysis and testing of new designs, diagnosing and resolving any mechanical or electrical issues.
• Integrating mechanical systems with actuators, sensors, fasteners, and electronics into cohesive robotic assemblies.
• Supporting simulation-to-real transfer by keeping CAD models, URDF, and physical builds tightly synchronized.
• Developing injection-molded components from concept through tooling and sampling.
• Preparing drawings, BOMs, and assembly documentation.
• Collaborating with vendors through production release.
• Maintaining clear revision history, supporting clean documentation for handoff to fabrication, assembly, or external vendors.

You are

• Someone with a Master's degree or PhD (or equivalent) in Mechanical Engineering or a related field.
• Experienced in designing complex mechanical systems.
• A hands-on builder who loves CAD design and 3D printing.
• Passionate and opinionated about technology and design.
• Always working on a side project and exploring the latest tools.
• Someone with a chip on their shoulder who gets a thrill from proving doubters wrong.
• Someone who loves good food and has strong opinions on the best restaurant within 2km.
