Would a human-like symbiotic pair of the same race be possible?

Would a human-like race be possible where the young and their parents live and work etc in a symbiotic pair?

My idea is inspired by the character(s) Ferra Torr from the game Mortal Kombat X, the young of the species would be the "˜jockey' and the old the "˜brute'. The young would be smart and cunning but weak and small and the old less intelligent but much stronger, tougher and bigger but in need of the jockey to guide and help the most of the time. This would mean the species must undergo a change at some point in which their muscles, bone etc. Would rapidly grow but parts of the brain responsible for thought and decision making would decay.

Would this mean an extreme puberty for the species could happen but one in which this is the only period of fertility so a mate must be found so the offspring can become the "˜jockeys'?

As a development on this how would they develop as a civilisation and what kinds of weapons and warfare might they use?

The world I imagine them to live is an arid desert and with an Aztec style of architecture and design. I also don't want any magic or sorcery just seeing if anyone can help me with ideas of how this species may have evolved and if it would be possible.
