Working as a resting pilot under FRMS rules for the [flight] departing ZZZ we heard a few loud pops from compressor stall of the Number 1 engine and then obvious loss of power. Looked out the window to see the first stage fan windmilling and no signs of fire or other damage. Sat tight for a bit to allow everyone to stabilize and then shared our thoughts with the forward cabin crew but also stating that any final word would have to come from the flying Captain and suggesting they just wait for him to call them which he did in a normal timely fashion given the situation. After confirming things in the cockpit were as we expected; engine shut down; no fire; preparing for return; I went to the back galley to make sure the aft cabin crew was fully informed and could expect a normal landing with fire trucks to follow with no need to prepare the cabin further yet be ready for evacuation if signal is given. We proceeded to land normally and have the AFR (Airport Fire Rescue) crews surround the aircraft. After taking the brake temps the left one was found to be hot; around 800 degrees F due to no thrust reverse on that engine and the braking system regulating more pressure to that side. The right brake was normal temp or about 300 F. The guys put a brake fan on it to speed up cooling and we then taxied to the gate with them in tow for an uneventful conclusion. Great job to both the flight and cabin crew in handling a startling event calmly and methodically.
