But LM is actively trying to reduce its number of Level 5, 6, and 7 engineers (the highest paybands on the technical career track). You would typically find a Level 5 engineer serving as an engineering technical team lead, a Level 6 as a site deputy chief engineer, and a Level 7 as a site chief engineer. A few years ago, LM Aeronautics offered all Level 5 and above engineers an early buyout/retirement and got over 1000 engineers to leave the company that way. Those engineers were largely not replaced, either in skills (hard to replace that level of expertise), billets (those jobs were not re-filled), or promotions (the sudden vacuum at the top end of the technical career pyramid was not filled by promoting large numbers of level 4 engineers to level 5, etc).
