Alright, I've had enough of this nonsense. List of games with either Engineering classes or some sort of punk setting to draw inspiration from:
Torchlight 2's Engineer is a popular recent example:
http://torchlight.wikia.com/wiki/Engineer
Also the Alchemist from TL1 fits the archetype:
http://torchlight.wikia.com/wiki/Alchemist
Then we have Diablo III's Demon Hunter and their various tech skills (turrets, rockets, grenades, and so on):
http://www.diablowiki.net/Demon_Hunter
The Traps Assassin of DII fits the bill:
http://diablo2.diablowiki.net/Assassin
Dungeon and Dragon's Artificer class is a classic (hurr) example:

How about Heimerdinger for MOBA fans?:
http://leagueoflegends.wikia.com/wiki/Heimerdinger
or Engineer from HoN?:
http://www.heroesofnewerth.com/heroe.../Engineer#hero
or even Tinker from DotA2:
http://dota2.gamepedia.com/Tinker
Granted that last one was really just a ripoff of Warcraft III's Tinker, but there're many more heroes within these three MOBAs that fit the archetype that I didn't mention.
Speaking of Warcraft III there's:
http://classic.battle.net/war3/neutr...intinker.shtml
and
http://classic.battle.net/war3/neutr...lchemist.shtml
and a bunch of other non-hero units I won't mention for the sake of brevity. I won't go into the different classes from the RPG books for the same reason.
Let's get back to the realm of MMO's. You mentioned SWTOR's Bounty Hunter:
http://www.swtor.com/holonet/classes/bounty-hunter
but failed to mention the Trooper:
http://www.swtor.com/holonet/classes/trooper
Admittedly a mirror of the former, but he has his own flavor.
There's also the Smuggler and the Imperial Agent:
http://www.swtor.com/holonet/classes/smuggler
http://www.swtor.com/holonet/classes/imperial-agent
All four classes have elements of the Engineer archetype.
We also have the aptly monikered Dwarven Engineer from Warhammer Online:
http://warhammeronline.wikia.com/wiki/Engineer
And more recently the Engineer profession from Guild Wars 2:

There's the futuristic Engineer from Firefall:

And the planeswalking Tactician of Rift:
http://rift.wikia.com/wiki/Tactician
But wait there's more!
Final fantasy has a myriad of jobs that fit snugly under the Engineer's umbrella, most notably the Chemist:
http://finalfantasy.wikia.com/wiki/Chemist_(Job)
and Gunner:
http://finalfantasy.wikia.com/wiki/Gunner
There was also an Engineer in Final Fantasy Tactics:
http://finalfantasy.wikia.com/wiki/Machinist_(Tactics)
and many Final Fantasy settings involve technology. VII, IX, and X come to mind.
In the land of FPSs we have TF2. The Engineer suits our purposes perfectly:

Most of the other classes work great as well.
Borderlands gave us Roland:
http://borderlands.wikia.com/wiki/Roland
and Borderlands 2 gave us Axton:
http://borderlands.wikia.com/wiki/Axton
BioShock is based entirely around a mix of Decopunk and Biopunk:
http://bioshock.wikia.com/wiki/BioShock_Wiki
and would theoretically fit this expansion's theme quite well if it proves to involve the undersea.
Dishonored is steampunk or "whalepunk" as some like to call it so some of the gadgets and tech could be utilized to get the gears turning:
http://dishonored.wikia.com/wiki/Dishonored_Wiki
Elder Scrolls isn't very steampunk for the most park, but there's still the Dwemer:
http://uesp.net/wiki/Lorewemer
The Fallout series is just awesome:
http://fallout.wikia.com/wiki/Fallout_Wiki
And how could we not include the Engineer class from the Mass Effect trilogy featured in each game?:
http://masseffect.wikia.com/wiki/Engineer
Fable certainly has some steampunkiness to it:
http://fable.wikia.com/wiki/Main_Page
Lots of good stuff in the Iron Brigade TD:
http://ironbrigade.wikia.com/wiki/Iron_Brigade_Wiki
If we look at RTSs we have Stracraft's Terrans:
http://starcraft.wikia.com/wiki/Terran
Damn near every unit has some Engineer flavor.
Same goes for 40k's Guardsmen:
http://dow.wikia.com/wiki/Retribution/Imperial_Guard
and Tau:
http://dow.wikia.com/wiki/The_Last_S...%27O_Commander
Atlantis was mentioned earlier. What about the Atlantis civ from Age of Mythology? They certainly had some tech:
http://ageofempires.wikia.com/wiki/Atlanteans
Hell lets go back a decade to Wizardry 8. It gave us the Gadgeteer and the Alchemist:
http://www.zimlab.com/wizardry/samjack/classes.html
So please people stop with this insipid blather of "Herp de der yous can't has it's not poosible!!!1" It's entirely fucking "poosible" you just haven't played enough godamn video games to see the "poosibilities."
I mean at the end of MMVII there were fucking laser rifles! Laser rifles!!!
