<p>I'm not sure if this is the right place for this question, but here it goes. </p>
<p>I've recently come to know that the companies mentioned above higher mechanical engineers, but what exactly do the mechanical engineers there do? </p>
<p>Think of designing the actual physical portion of a mobile phone, tablet, or computer. Consider the aesthetic, functionality, reliability, and durability aspects of the design.</p>
<p>In such lines of work the biggest challenge is often mechanical design - people have gotten pickier and demand excellent mechanical design … I thought software and HCI were difficult till I saw what it took to ensure our product does not go up in flames due to overheating. </p>
<p>but doesn’t all of them involve some sort of electrical expertise? I’m not interested in the electrical engineering part. Moreover I found that M.Engineers work on building cooling systems? </p>
<p>The work is generally segmented - the software people do software, the EE’s do the nuts and bolts and maybe some software, the MechE’s do all kinds of work related to the physical product from designing the laser etch process for the button labels to making sure the right color shade is used on plastic to the actual chassis, removable components, and so on. Then if the thing puts out a lot of heat (say, a tablet or laptop) then they do the heat dissipation calcs, etc. There’s some expertise to understand related disciplines (i.e. the EE designer will place, say, a microSD card reader connector on his board. The CAD library already has the specific part’s dimensions and so on, so the MechE knows how much space is needed, etc. Typically projects have a lead engineer who understands enough of everything to keep everyone else talking. </p>
<p>Fun stuff.</p>
