Narrative:

[We were a] sequenced departure from runway 18R in trail of previous departing aircraft. Cleared for OLMS2 RNAV to emiit; FMS loaded; LNAV armed. Normal rotation; liftoff and climb; at 1;000 ft VNAV engaged and autopilot on; tracking normally toward emiit. Passing 1;500 ft the aircraft rolls left; about 15 degrees of bank; with a slight yaw. Not normal; so I disconnect the autopilot and try to correct right with normal aileron. No response. Applied almost full right aileron to break out of what I believe to be a wake turbulence encounter from the previously departed aircraft. Corrected back on course with no further turbulence encountered. Wind 180/4 at takeoff. [We] notified tower and departure control of event; tower as it was occurring and departure a few moments later. Suspect light tailwind may have created the environment for this to occur. Providing this information as data to evaluate recat under these conditions. I have never experienced this type of situation before and consider myself a fan of recat.
