I feel Engineering grads should venture into L&D and minimally be a stand-up trainer for soft-skills e.g. customer service. You can also be seen as a consultant to help employees customise and conduct in-house training courses, so that staff are well-trained and uphold certain KPIs like customer service.

Get an ACTA (Advanced Certificate in Training and Assessment) cert where you can be a WDA-certified trainer, to teach WSQ courses. You may retire as a freelance trainer eventually.

Importantly you must go to a company with good spectrum of in-house courses where you can conduct, so that it can be a good learning ground for you.
