Narrative:
We encountered wake turbulence on the RNAV dawgs departure after departure shortly behind a B757. We were RNAV off the ground; runway 27R. A B757 was just lifting off [runway] 27R when we were cleared for takeoff with the RNAV SID routing. After liftoff I called for gear up; speed mode; and LNAV. At about 1;000 AGL (while manually flying with the flight director on) I called for flight level change and pitched the nose to accelerate to 240 KTS per out SOP. Shortly thereafter the aircraft encountered wake turbulence characterized by turbulent air and the aircraft rolled approximately 10 degrees and I corrected with opposite aileron input. I was able to correct the roll and the flight proceeded along the dawgs RNAV SID. We did not notify the controller about the wake encounter as I believe is typical regarding pilots and wake encounters. I thought about asking the captain; who was the pilot not flying; to let ATC know but I did not and we were busy flying the SID and running after takeoff flows and checklists.
