The Story
- Mechanical Design Engineer
- Product Design Engineer
- Manufacturing Engineer
I have been working as an Oracle Developer for the past decade and consider myself an expert, especially in performance tuning and database optimization. I have started to feel disconnected, unsatisfied, and in disagreement with the direction the industry is heading. I am looking for a career change to pursue my passion for mechanical design and engineering. Long ago, I studied at a school with a focus on automation, where we learned about mechanical systems, pneumatics, logical gates, hydraulics, and PLC programming. At that time, it was just school, but here I am now, seeking a way to return to that world and start building things again instead of only writing database code that no longer excites me.
I understand that success in mechanical design is not only about the ability to use SolidWorks, but also about tolerancing, knowledge of materials, and manufacturing processes. Therefore, I have taken some Udemy courses and continue self-education in these areas. This path was suggested by my school colleagues, together with GPT.
I am looking for jobs somewhat from this list
