Mechanical Engineer

The role

This person will design, build, and scale mechanical systems for robots and data collection devices. The role involves working across the full product lifecycle from 3D CAD to manufacturing handoff.

What you will do

• Support the design and development of mechanical components and assemblies for wearable and robotic devices
• Rapidly prototype, test, and iterate on designs to improve performance and reliability
• Contribute to DFM/DFA efforts to ensure designs can scale from low-volume prototypes to high-volume production
• Work with vendors and suppliers on prototyping, tooling, and production readiness
• Perform basic analyses (tolerance, structural, thermal) to validate design decisions
• Assist in documentation for design reviews, testing, and production release
• Collaborate with cross-functional teams to integrate mechanical systems

Required qualifications

• 2+ years of mechanical engineering experience
• Strong skills in CAD
• Familiarity with rapid prototyping techniques (3D printing, machining, etc.)
• Understanding of DFM/DFA principles
• Hands-on problem-solving approach
• Strong collaboration skills
• Comfort working in fast-paced startup environments
• Bachelor’s degree in Mechanical Engineering or related field

Nice to have

• OnShape or SolidWorks preferred
• Experience working on consumer hardware, robotics, or compact devices is a plus
• Master’s a plus, but not required
