if I may put in my 'downer' opinion ...
Though it's a classic, none of the 'top ops' sort of backstories really work, and that's for two reasons. (The rich-kid story doesn't work for the first reason.)
The first is that the gear available to that sort of person, the stuff they hand them (and expect back at the end of the op), is of a quality
well above the gear you have available to you as standard at game start. Your character can get/have a Sony CIY-720 at best, and while this is a great piece of gear, it isn't the
nano-edge tech that real black ops (or amazingly wealthy) people have - that would be the Shiawase Cyber-5 at worst, or else something on the lines of the Fairlight Excalibur or better.
The second is that even if you top out your necessary skill(s) at 6, you aren't going to be in the range of a
real black-ops individual. Those sorts have them at 8 and 9 - get in, get the job done, get out again. 'Take care of opposition' is an optional for them (unless that's the job), because there ain't no better op than one that the other side never knows happened.
... and then inject minor alterations to be less of a downer?
SpecOps can still work, but more/better if this is someone who is still in training. They get 'light' gear, they don't have the totally killer skills yet, that sort of thing. They're on a 'training op' - which in SR can be an actual, but comparatively lowballed, operation, simply something more their speed. Taking down a bothersome group of gangers in the Barrens, eliminating an up-and-coming shadowrun team, running interference for the 'A' Squad, whatever it happens to be, but like with other things, 'something goes wrong' and they get left for dead, out in the cold, find themselves betrayed, whatever.
Another way is for a techno to encounter this sort of 'training op gone sour' and do some recovery of their gear. Imagine a ganger who's only been able to afford a datajack and a Renraku Sensei being able to find, repair, and explore with a Renraku Tsurugi - something that lets him make the jump from wanna-be to gonna-be.
Or take an alternate Mr. Rich Kid. Oh, he has - sorry,
had - an Excalibur at home; the Sony is his 'toy' deck, something he last used six years ago when he was still cutting his teeth on 'light' targets, or maybe it's his 'game deck', one that carries an alternate ID for him, whatever. It was in his gaming / old kid hangout space when the house blew up, or the corporation came to repossess everything (and didn't check in there), or whatever - instead of being 'what he can afford', it becomes a significant step down from what he's used to. (And gosh gee, now he has to actually
work to claw his way back up to what he had before.)
If he's a mentored kid, perhaps it's his mentor's gift - said mentor being well past 'that cheap-ass deck' - before the mentor is all but cutting him loose. "Time you learned the lessons in the street, Homer. I can't teach you those."
The deck for the 'downsized' corporate almost-security-hacker is his own build, something he was putting together at home - filch a part here, a motherboard there, and hey, he was looking at a real deck ... and then his boss got fried in a scandal, and Downsized Corporate Drone was canned from the backsplash.
Just remember that when it comes to skills a 4 can get you a job, and a 6 is quite respectable ... but think of it more that 4 is 'low/middle-scale college ball' and 6 is 'just breaking into the professional league'.
