For 25 years I worked as a Design Engineer and Drawing Office Manager – for a company that manufactures boiler cleaning equipment (aka Sootblowers). I retired early five years ago.
I really liked my job as I had relatively free reign to do what I thought was right without any real pressure from upper management. At one point I even managed to get a (joint) world patent on a new design we came up with.
However, at one point, late in my career, said upper management decided to appoint a Technical Manager to be in charge of me and my group. This person was a Fellow of the Instutution of Mechanical Engineers. Holy sh1t he was an ar5e of the highest calibre and a real disgrace to the engineering profession. His big contribution to the company was to change my job title from Engineering Manager to Principal Design Engineer. During his short tenure (he was sacked after only 1 year) his effect on my attitude was profound and was highly instrumental in my determination to retire early (I’d always planned to retire at 60).
Now I potter about with riding bikes, engineering stuff (still use Soilid Edge 3D CAD with a home license), fixing cars and bikes and making stuff on my lathe. Retirement has, so far, been fantastic.
