Your job as a developer is to write code and piece code together to make your life easier. That includes taking the work that others have done and make it work to suit your code base.
On a mine site, the job is to mine and process minerals. That includes engineering a mine using products that eventually fail over time and need fixing. As part of that process an automotive electrician may need to fix the electronics on a vehicle that have become faulty or damaged.
Mechanics and engineers need to inspect, rebuild, and fix the tools they are given to do their job. The difference is that yours may not work up front, whereas these tools need maintenance over time.
