Bombshell Genius
In the five years leading up to Omega, Jessica discovered she was a latent Force-sensitive. She would be a middle-aged woman by this point, with a toddler for a child (I will remain vague about the child for the time being) and she feels that she needs to be trained in the ways of the Force. For now she can conceal her presence in the Force, and do Force-sense as well as mechu-deru.
Long story short, she lived her pre-Omega life as if she was unable to use the Force, and yet, has a rather loaded history with dark-siders, so a light-sider is non-negotiable, preferably a Silver. But it is obvious, given her past career as a developer of starship components, how she will end up becoming: a Jedi Technician. (Think Kazdan Paratus or similar; if someone can train Jessica with a lightsaber pike, she will eventually go claim Kazdan's lightsaber pike as her own)
