"Ingeniøren jobber med meg."

Translation: The engineer works with me.

Is there any important difference between arbeider and jobber?

[fveldig]

Not really, but 'jobber' is used more often colloquially.

[peoplearestrxnge]

So 'the engineer's working with me' is wrong??

Ive found that Duolingo doesnt like contractions very much, try to avoid them as much as possible

[ChromateX]

As in, the construction's right, but the contraction is ambiguous, so try to avoid it.
