Summary
Josh Grace bridges mechanical engineering, software, data, manufacturing, and hands-on fabrication to turn difficult ideas into working systems.
Experience
Founded and operated an excavation, drainage, property-service, and winter-operations business while continuing an engineering career.
- Customer estimating, project planning, scheduling
- Equipment operation, excavation and grading, drainage systems
- Snow and ice operations, material estimation, subcontractor coordination
- Billing and reporting, equipment troubleshooting, welding and repair
- Field decision-making, safety and risk management
- Website and software development, business operations
Supported race-weekend preparation, maintenance, inspection, troubleshooting, and paddock operations for a purpose-built D Sports Racing prototype. Worked with the team under time constraints to help prepare and maintain the vehicle throughout club-racing events.
Mechanical and tooling design, aerospace product support, CAD data quality, engineering drawings, design reviews, configuration and revision control, and manufacturing liaison work across engineering, manufacturing, suppliers, and customers.
