Flight crew reported loss of oil pressure on the #1 Engine after take off. The flight crew performed an inflight shut down of the affected engine and returned to departure airport.
We had a normal push back; deice (type 1 and 4;) taxi; and takeoff. About the time that I pulled the thrust back from flex to climb; we both noticed that the Oil Quantity on the number One Engine was 0.5 quarts and flashing. Almost immediately after that the Oil Pressure went to zero and we got the Master Warning with the associated ECAM for Low Oil Pressure. We handled the abnormal via our training and SOP and shut down the Number One Engine as directed by ECAM actions. I continued flying and worked the radios while the captain accomplished follow up actions and ran the overweight landing QRH procedure. We were given vectors for the ILS XXR and after a soft touchdown we came to a stop on the Runway for ARFF inspection. After the all clear we taxied to the Gate. The Captain entered the engine shutdown and the overweight landing in the AML. It was apparent that somehow the number one engine had a malfunction which caused it to lose all oil and oil pressure; which forced a shutdown. As I am not an A&P; I'm not sure what could prevent this mechanical failure. I believe that our response to the event was as we were trained and according to company procedures. I think that all the single engine training we get every year in the sim prepared us well for this event; as it occurred in a very similar way as we train.
After takeoff at climb thrust reduction altitude the Oil Quantity on #1 Engine was indicating (flashing) low. We continued with the After Takeoff flow and checklist and leveled at 5;000 MSL. The low oil condition continued and resulted in an ENG1 OIL LO PR ECAM. The number 1 Engine was shutdown IAW the ECAM and all procedures and follow up was accomplished in accordance with Company Standard Operating Procedures and training. We returned to ZZZ for a single engine overweight landing; was cleared by Crash/Fire and taxied to the Gate.
