Bertrand Serlet was already at NeXT. He designed Workspace Manager, so he must have been there since around 1988.
I think that makes Serlet one of Jobs's most long-term colleagues. His deep experience of software evolution processes may be one of Apple's most underestimated assets.
The NeXT platform has gone through seven different CPU architectures (by my count) and an enormous API merger with the Mac OS, yet shows no signs of getting bogged down. Most other companies can't seem to manage an operating system for even a decade before it loses its momentum under feature bloat and internal fighting over direction (c.f. Windows Vista, Symbian).
(edit -- I initially wrote that Serlet designed Interface Builder for NeXT, but that was another Frenchman, Jean-Marie Hullot.)
