CAD Engineer for Drone Payload V2 Design Refinement

I’m looking for an experienced CAD/mechanical design engineer to help refine a V2 design for a compact drone-mounted sensor payload. I already have a base design and clear feedback for the next revision. The overall design changes should be relatively minimal, but I need someone who can carefully update the CAD and validate a few critical mechanical/optical constraints. The payload involves a fixed camera and a rotating scan-head assembly used to redirect the sensor’s field of view. The goal of this V2 pass is to improve the design for weight, balance, sensor field-of-view coverage, and drone integration. Primary responsibilities: • Review the existing/base CAD design • Implement V2 design feedback and requested mechanical tweaks • Ensure the payload has a balanced center of gravity suitable for drone mounting • Use CAD and/or simulation tools to evaluate balance, mass distribution, and rotation stability • Accurately model/project the camera sensor’s field of view through the scan-head geometry • Check for field-of-view clipping, vignetting, or mechanical interference Required experience: • Strong CAD experience, ideally Fusion 360, SolidWorks, Onshape, or similar • Mechanical design experience with small assemblies • Ability to evaluate center of gravity, mass properties, and balance • Ability to model or simulate sensor field-of-view geometry • Comfortable working from an existing design rather than starting from scratch • Able to move quickly and communicate clearly Huge plus if you have experience with: • Drone payloads or UAV-mounted hardware • Lightweight mechanical design • Rotating assemblies • Optical/sensor field-of-view modeling • Cameras or imaging payloads • Electrical engineering or basic electronics integration • 3D printing / prototype-ready mechanical design Also bonus if you live in or near Southern Utah (where I'm located). Timeline: I’m looking for a quick turnaround and will hire immediately. Since this is a V2 refinement based on an existing design, I’d ideally like the updated design returned in under one week.

By accepting the job, you agree not to share, reuse, publish, or disclose any project details, files, or designs without written permission. Please include examples of relevant CAD/mechanical design work, especially anything involving drones, lightweight payloads, rotating assemblies, or sensor/optical field-of-view modeling.
