NOT in the Copper! 3D Animation of a Signal Through a VIA | Yuriy Shlepnev

<div class="entry-content"> <p><strong><span style="color:#ff0000;">CLOSED!</span></strong> This is a great opportunity. I am encouraging you to apply for a Digital Hardware Design Engineer position in FEDEVEL.</p> <p>You will be working alone or together with me on projects which are continuously coming in. Majority of projects are Processor Board Desing (ARM, x86,), but includes also jobs like Base Board development or PCB layout only. This position is mostly about Schematic design and PCB layout (including High Speed), but I do also HW debugging (bringing the new boards up) and Software development (porting bootloader and OS to the new boards) â€“ depends what you will be interested in.</p> <p>This is a FULL TIME contract position and as I work from home for clients around the word, your location is not important. Anyone can apply.</p> <p>If you learn quickly, you are self driven / self motivated and responsible, don't hesitate and send your CV with cover letter explaining <em>Why you would like to work for FEDEVEL</em> to&nbsp;<a href="http://www.fedevel.com/welldoneblog/wp-content/uploads/2012/03/email-1.png"><img loading="lazy" data-attachment-id="1820" data-permalink="https://welldoneblog.fedevel.com/2012/03/19/seeking-digital-hardware-design-engineer-full-time-contract-in-fedevel-anyone-can-apply/email-1/" data-orig-file="https://welldoneblogfedevel.files.wordpress.com/2019/10/f4cc0-email-1.png" data-orig-size="181,22" data-comments-opened="1" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="email (1)" data-image-description="" data-image-caption="" data-medium-file="https://welldoneblogfedevel.files.wordpress.com/2019/10/f4cc0-email-1.png?w=181" data-large-file="https://welldoneblogfedevel.files.wordpress.com/2019/10/f4cc0-email-1.png?w=181" class="alignnone size-full wp-image-1820" title="email (1)" src="https://i0.wp.com/www.fedevel.com/welldoneblog/wp-content/uploads/2012/03/email-1.png" alt="" width="181" height="22"></a></p> <p>Thank you,</p> <p>Robert Feranec</p> </div>
