Aircraft
Talking off out of ZZZZ on Runway XXL. On the takeoff roll we got a NAI over-temp on engine #2. No master warning. We continued the takeoff and after rotation we got engine fire #2. We let it produce thrust due to a high climb gradient. We ran the Quick Action items followed by the engine fire #2 checklist. After doing so; the fire indication went away. The aircraft was above max landing weight so we decided to tell ATC that we needed to return. We proceeded to run the jettison checklist and climbed to 6;000 feet. We got vectored around the missed approach area of Runway XXL. We talked to the company and Maintenance and advised them of the situation. We got time and initials for a re-dispatch back to departure airport. We requested priority handling to return for landing. After landing and clearing the runway; [it was determined it was safe to taxi] to our gate. After we got to the gate; Maintenance opened the cowlings and determined there were a lot of melted wires.
