As for liquidated damages, it depends on how you sign the contract. As long as your behavior does not harm the interests of the company and does not violate the contract, the company has no right to ask you to pay the liquidated damages yourself.
But then again, I think the engineering department is quite trained. If you are young, you can actually consider going to the engineering department to exercise. People can't be too comfortable, can they? !
Anyway, one person and one idea, I wish you good luck in your work!
