Pros
As an engineer, if you like to work abroad and play an active role to devlop not only battery cell performance but its manufacturing process, then it would be a great experience. Unlike other manufacturing driven company, SDI has been increasing its production capability aggresively, so it also could be a good chance to experience how to make the stable position and credible reputation in an expanding market such as battery value chain for electric vehicles.
Cons
If you really enjoy and prefer fundamental research rather than developing or sophisticating some engineered products, then it might be a good choice for you to find another job. As mentioned above, since electric vehicle battery market is so competitive, the company does not allow us enough time to concentrate basic research. Even if it is permitted, it should be very limited.
