Mechanical Design Engineer

About this role

Design mechanical parts and sub-assemblies for a home cleaning robot from concept through high-volume production. You'll own the complete lifecycle of your designs—prototyping, testing, tooling, and field support—working in a small, collaborative team where rapid iteration and shipping to real customers happens within months.

What you'll do

• Design parts and sub-assemblies within defined architecture and drive them to mass production
• Build prototypes, test for performance and durability, and iterate rapidly based on results
• Develop and execute accelerated test plans to predict field behavior and validate designs
• Create production-ready 2D drawings with proper GD&T and tolerancing for supplier quoting
• Collaborate with vendors and contract manufacturers on design-for-manufacturing, tooling, and first article inspections
• Partner across electrical, firmware, software, and industrial design teams to balance subsystem trade-offs

What they're looking for

• Mechanical design and CAD proficiency
• High-volume manufacturing processes (injection molding, die casting, stamping, or metal injection molding)
• GD&T application and tolerance stack-up analysis
• Component testing and reliability engineering
• Technical drawing and documentation standards
• Problem-solving and cross-functional collaboration
• Supplier and vendor management
• Hands-on prototyping and fixture building
