Thought I'd grab these screenshots before they disappear. It's ironic that they still list B. Todd as the "Acting Director."
In the meantime, here's stuff on Brandon:

PDF was available, titled "Feb 27, 2014 - Statement of Thomas E. Brandon, Deputy Director. Bureau of Alcohol, Tobacco, Firearms and Explosives. U.S. Department of Justice." Click the link, wait for awhile, and you get "SIte Under Maintenance" - how convenient.

Bloomberg doesn't list his specific assignments, prior to October 2011. Just "various." Of course.

Here's a statement from ATF, on him. Link to it is here:
https://www.atf.gov/content/atf-announces-b-todd-jones-depart
Says he wasn't in Phoenix until March 2011...
Brandon has more than 26 years of experience with ATF. Prior to his appointment as Deputy Director, Brandon served as the special agent in charge of the Phoenix field division beginning in March 2011, and special agent in charge of the Detroit field division from January 2008 until his assignment to Phoenix.
...so, if he wasn't in Phoenix when F&F happened, he was assigned there in March 2011. USBP Agent Brian Terry was killed by the F&F-walked AK in December 2010. Brandon is assigned in March 2011. Brandon, as Deputy Director, is later in charge of who will be punished, not punished, fired (nobody was fired), etc...
Screenshots I grabbed, while they're still fresh:
