BioWare is opening jobs for modders, or rather, the lucky winners of the new world building contest if their winning entries are great enough and if they perhaps meet some additional conditions at BioWare's discretion. The new folks will be working in Austin, Texas, on BioWare's first MMORPG. Here's a snip:

Here is what you need to know to enter:
BioWare asks for designers to create a Neverwinter Nights adventure to showcase their world design skills using the Neverwinter Nights 1 Aurora Toolset. There are a lot of options to consider when creating a module in the Toolset, but it is important to remember that we will be mainly looking at the technical skills and creative level design used.

When hiring world designers, BioWare looks at your scripting/technical abilities, your creative level design skills, your ability to create cinematic moments, and your ability to create interesting and fun puzzles. Because BioWare is known for quality, we also value a world designer's ability to create stable, bug free work that is well documented.
