• Experience with CAD tools and ability to interpret models/drawings and BOMs.
• Strong attention to detail and data-driven mindset; maintain traceable records.
• Clear communication and collaboration across cross-functional teams.

Responsibilities

• Build and maintain mass properties estimates (weight, CG, inertia) using CAD data and measured weights.
• Support weight tracking by reconciling changes with baselines and communicating deltas and risks.
• Assist with part/subassembly weighing activities, data collection, and documentation for traceability.
• Perform first-principles calculations and sanity checks on mass properties inputs/ outputs.
• Develop spreadsheets, dashboards, or scripts (Excel, Python, MATLAB) to automate data ingestion and reporting.
• Collaborate with design, manufacturing, and flight test teams to close data gaps and mitigate weight risks.
