• Develop mechanisms for drive systems, brush assemblies, linkages, and enclosures
• Perform DFMEA, material selection, weight optimization, and stress analysis
• Collaborate with electronics and controls team for system integration (motors, sensors, PCBs)
• Prepare detailed manufacturing drawings, BOMs, and documentation
• Manage prototyping, field testing, and iteration based on real-world feedback
• Work with vendors for CNC, sheet metal, and machining component fabrication
• Ensure design reliability in outdoor, high-soiling, high-temperature environments

Qualifications

• Design Engineering, Machine Design, and Product Design skills
• Mechanical Engineering and Computer-Aided Design (CAD) proficiency
• Strong analytical and problem-solving skills
• Excellent written and verbal communication skills
• Ability to work collaboratively in a team environment
• Bachelor's degree in Mechanical Engineering or related field
• Experience in the renewable energy robotics is a plus
