Steve Jobs was and remains a most enigmatic individual, driven by product excellence, focused  to an obsessive degree but with little empathy for those around him.  Below is a is an interesting paper on Jobs, by Bert McBrayer, within the framework of the Big 5 Personality traits.  Bert concludes that history will likely paint Jobs as an innovator but likely not include him in the pantheon of leaders of people.

My take on Steve Jobs

Openness:  Above average aspect Intellect but off the scale aspect Openness.  Likely out of 100 people he would be more open to experience than the 99 other people in the room.

Conscientiousness: Off the scale aspect Industriousness but low in aspect Organization.  What make Jobs unusual is the focus of his Industriousness.

Extraversion:  Off the scale for both aspects Enthusiasm and Assertiveness

Agreeableness:  Very low aspect Empathy and Politeness but could modify both if this furthered his product goals

Neuroticism:  A reliable indicator of suitability for management is a low-level of Neuroticism or reaction and response to negative events.  Jobs was legendary for his volatility but appears to have had low levels of withdrawal.

What appears to have made Jobs unique was his remarkable Industriousness and focus, combined with the creativity commensurate with above average intellect and exceedingly high openness.  He used with pleasure his high Aspect Volatility in combination with his low Trait Agreeableness bound into a laser like product focus to stimulate his team.  Steve was product and not people focused and may have retreated from the “scar tissue” of his rejection as an infant into the infinite detail of product design and artistic endeavour.
