I'll Trade You an Air Purifier for a Job Lead
I'm a mechanical engineer who designed and built a freestanding room air purifier from scratch. Send me a legit job lead, and I'll send you the CAD files. Get me an interview? I'll mail you a parts kit.
Freestanding MERV 13 Air Purifier
Optimized for High Flow and Low Noise
Most consumer air purifiers are too small to be effective, too loud when they are effective, and grossly overpriced. This one is designed with exclusively off-the-shelf or 3D printed parts for ease of filter replacement and drastically lower cost.
What I'm Offering
The better the lead, the more you get. Leads will be verified for uniqueness — no recycled LinkedIn Easy Apply links please.

The Engineer Behind This
Noah Probst
I'm a mechanical engineer who believes the best way to show what you can do is to actually do it. I hope this air purifier shows my approach and ability to optimize a solution for a problem from start to finish.
I'm looking for roles where I can bring this same approach: understanding the problem deeply, designing thoughtfully, and building things that actually work.
What I'm looking for: Product design, mechanical engineering, or R&D roles. Open to startups and established companies. Currently, based in Colorado, open to relocation / remote.
Need Something Designed & Built?
The air purifier is simply one of my more practical projects, I’m always working on something. If you have a project that you think I can help with, let’s talk!
Mechanical Engineering
From napkin sketch to production-ready design. I'll take your concept through analysis, prototyping, and design-for-manufacturing so it's ready for the real world.
3D Modeling & CAD
Detailed solid models, assemblies, and technical drawings in OnShape. Whether you need a single part or a full product, I'll deliver files you can actually manufacture from.
3D Printing & Prototyping
Functional prototypes and small-batch production runs in FDM. I handle material selection, print optimization, and post-processing — you get parts that work.
Small jobs welcome. No project is too weird.
