Narrative:

Takeoff out of ZZZ; reduced thrust takeoff on the abc departure. The takeoff was uneventful through initial flap retraction. At about 1400 ft MSL; we heard a large bang; slight yaw with loss of thrust. An engine scan with 'engine fail' light confirmed a #2 engine failure. There were no overheat or fire indications. I; captain; was flying with the HUD down; autoplt and LNAV were engaged. Initially; autoplt handled jet fine; however; I disengaged autoplt so I could level off and finish raising the flaps. Once that was complete and thrust was set; I re-engaged autoplt. We declared an emergency and ATC started us on a box pattern for runway. We ran the engine failure checklist and the 1 engine inoperative landing checklist. We landed flaps 15 degrees uneventfully and cleared the runway. Fire coverage was present and they reported no fire or abnormal indications. We taxied to the gate and gave the jet to maintenance.
