Here's a character i constructed that could serve as a hacker/programming specialist on the ship.
Let me know if you're interested.
---------
Name: Eva Manning
Alias: "Eve" - only really close friends. 
Age: 19
Sex: Female
Occupation: Hacker/Programming specialist.

Appearance: Totally flat chested and bald. Her thin black eyebrows make her look angry most of the time, which is not far from the truth. Little pointy nose, manly lips and high cheek bones give her a confusing appearance. Her facial features do have some indication of her gender yet no one has ever thought her to be a woman at first sight. If you looked at her knowing she's woman you could find her beauty, but it didn't stand out in the least bit.

Height: 1.70 meters (5'7")

Weight: 64 kilos (140 lbs)

Personality: Although she's a programmer, in the real world her decisions are highly irrational and she tends to act on instinct. She's quick to judge people, for better or for worse; mostly for worse. When you do get on her good side she prefers a distant relationship and would almost never be the one to strike up a conversation. That's not to say she's cold hearted, she just likes a lot of mystery in her relationships and believes that unspoken emotions are the building blocks of long lasting friendship. She tends to be quiet yet when something is important to her she will be extremely rude and audacious until she get what she wants. She virtually has no morals and codes and would do anything to protect herself and those she care about. Underneath her rough skin she's secretly afraid of many things, among them talking to new people, facing dangerous situations, and talking openly about her feelings. She hates it when people say obvious remarks and quickly categorize those who do as dimwits. She's highly emotional and so to earn her acceptance you should appeal to her emotions and not to her intellect.

History: She keeps her past a well-kept secret but she is smart enough to reveal enough so she could be left alone. Born to a high ranking noble family in one of the central planets, at age 11 she got arrested for cyber-crimes and was sent to juvenile hall where she spent most of her early teens. 

Gear: A touch-pad computer, a knife (which she is not that bad at handling) and a pack of gums she chews on at all times.

Misc: There's a weird phrase she uses whenever she wishes to ridicule someone: 

"Please… don't exercise" / "Don't even exercise!"
