Mechanical Engineer

Today, building robots and intelligent machines means navigating fragmented tools, incompatible hardware, and closed ecosystems. It takes too long, costs too much, and locks builders in.

There is no default platform for physical AI. We're building it.

Spring craft brings together purpose-built hardware, developer tools, and AI models into one open, integrated system so that builders can create machines that sense, understand, and act in the real world.

Founded by the team behind 8th Wall, the largest AR platform for the web (acquired by Niantic), we bring deep experience in spatial computing. Backed by Night Capital, Eric Semler of TCS Capital, Village Global, and exceptional angels, we’re based in Palo Alto and hiring our core team now.

You will own physical product design across the Spring craft platform, starting with our motion control systems. You'll take internal mechanical assemblies from prototype to production and design the open-source reference designs for the builder community.

This is a foundational hire. You'll define how everything we build looks, feels, and comes together.

Spring craft is built on open hardware and open standards. Your designs will be used by developers, researchers, and builders around the world.

Design and iterate mechanical components and assemblies in CAD, including motor and actuator integration, sensor mounting, and cable routing

Specify hardware, tolerances, materials, and fastening strategies across the product line

Define open mechanical design specifications and review community contributions for compatibility

Ensure mechanical safety compliance across moving parts and user-facing surfaces

Prototype using in-house and external fabrication (3D printing, CNC, sheet metal) with assembly and bring-up of early units, designing for manufacturability

Source mechanical components and manage supplier relationships

Own the contract manufacturer relationship for mechanical parts and assemblies

Own and maintain the master BOM, CAD files, and engineering documentation

Collaborate with Electrical and Mechatronics Engineers on physical integration and contribute to hardware architecture decisions as the platform and product catalog expand

2+ years of professional or academic experience in mechanical engineering

Strong CAD skills (Solid Works, Fusion 360, or equivalent)

Practical prototyping experience

Understanding of GD&T, tolerancing, material selection, and basic structural analysis

Ready to own the full lifecycle: design, prototyping, validation, and manufacturing

Authorized to work in the United States, we are unable to sponsor work visas at this time

Experience in robotics or precision motion systems

Experience taking a product from prototype to production in a startup or small-batch environment, including working with contract manufacturers

Experience with sensor mounting, thermal considerations, or other electromechanical integration challenges

Industrial design sensibility or experience with product aesthetics

This role requires full-time, in-person work at our Palo Alto, CA office.

Competitive salary ($100,000-$180,000) + meaningful early-stage equity

Health, dental, and vision insurance

Paid time off and holidays

Spring craft is an equal opportunity employer.
