Jobs was actually a technician at Atari, assembling circuit boards during the night shift. Jobs was later paid by Atari to make Breakout, but basically subcontracted it to Wozniak for 50% of the contract. Jobs ended up paying Wozniak less than 1/10 of how much Atari paid him.

An "engineer" that out sourced his work to Wozniak while at Atari

Calling him an engineer would be a stretch. As others aid, he was a hardware technician on an assembly line.

That said, that experience, and this article, that Jobs had an understanding of computers and electronics when founding Apple beyond the "Woz = engineer, Jobs = sales guy" oversimplification. It's just that compared to Woz—one of the century's greatest engineering minds—anyone would look third-rate.
