I think it must be mentioned that in addition to fission and fusion (ITER) work, General Atomics is the creator of the MQ-9 Reaper, which is commonly used for drone strikes. A software job at this company may involve work on these aircraft.
Your parent merely notified us that more than one type of product is in development at that company and one that is not fusion is specifically designed to kill people.
I've dreamed about getting into fusion research myself, and concluded the best pivot would be to help with the plasma simulations at a university while obtaining a PhD.
