The Avalanche will make quick work of the platforms, as suggested, if you go with it.
For your squad, I'd suggest a Warpbombing pair. Your best bet, if you Infiltrator doesn't already have Warp Ammo, is Thane (for Unstable Warp and Throw) and Jack (for Squad Warp Ammo and Pull). Often times when the first platform lands, you can instantly strip the defenses of the first Collector (just pause as it's landing and hit the focus both squadmates fire on target enemy button). The next instant after it's barrier is removed, pause again, hit that focus fire button on a different enemy (to prevent them from killing the first), then Pull-Warp that first target. More often than not, the blast from the Unstable Warpbomb knocks the other standard Collector Drone right off the platform. This method can be repeated for each Collector filled platform that lands; a great way to start each fight.
The Scions' Shockwaves are what will kill your squadmates more than anything else here. It's kind of hard to avoid that. It will also instantly strip your shields too, while leaving you staggered out of cover to get shot dead. You need to know at all time where that Scion is so you can not only position for the best cover against the Collectors but also to avoid the Shockwave's line of fire. Pause a lot if you need to, until you get the hang of these platforms.
When the battle first starts, place both of them behind the middle cover of your starting platform, while you yourself will be moving around to dodge attacks and set up shots. However once that second platform lands, I'd hit the regroup button or the Collectors will have the perfect angle to shoot them if they're still there. After clearing that second platform of Collectors, charge the second Scion platform that lands and take it out as quickly as you can manage. Then use the heavy weapon ammo crate there to refill all your guns' ammo before the last Collector platform docks.
And lastly, don't forget your Medi-gel for when you are near death (hopefully you upgraded it fully)!
