Narrative:

During an ETOPS service check, I was pressured into performing maintenance that I was not qualified to perform. A qualified mechanic told me to do the work and he would sign for it. Overwater job card was complied with and the aircraft departed ZZZ1 and diverted into ZZZ2 after an in-flight shutdown due to loss of oil pressure on #2 engine. After being informed the next day of the situation, I found documentation in training records stating that I was not qualified to perform the maintenance regardless of who signed for the work. I was informed that the in-flight shutdown was caused due to an oil sump line not safety wired. I recall doublechking the torque on the line and not seeing a place to safety the line. The line was leak checked twice after maintenance was complete. Some of the human factors involved are due to working late at night in the dark and pouring rain. Other factors involve other qualified amt's not doing their job, forcing me to pick up the slack out of fear of being reprimanded by lead amt's and supervisors. There were many other ETOPS qualified amt's at work that night that were not assigned to that aircraft thus forcing non-equipment-qualified amt's to do work they are not qualified for.
