- Save money for an important occasion;
- Start a small business; or simply
- Put money toward your financial freedom goals.
With that said, here are the best side hustles for engineers.

Ever since online betting was legalized, many people have turned to this as a way to make money online.
The sports betting side hustle can be quite lucrative indeed. BUT, I only recommend it if you are willing to lose some money in the process.

Although this is a higher risk than most other options here, it’s a potentially lucrative side hustle for engineers that are skilled in analytical models and can increase the odds of winning by mapping out major sports and then placing bets on them.
