On our flight deck preflight; we noticed the MAINT light illuminated and initially thought that was a problem. However; after some discussion and after it went out when starting engines; we decided all was fine. On landing we got a Master Caution and overhead light on rollout along with the MAINT light. As we investigated further we discovered that our initial concerns on preflight were correct. The MAINT light should be extinguished on preflight. If on it is designed to go out at engine start; (though I don't know why if it is non-dispatchable) and return 30 seconds after landing. Neither of us has much experience in the MAX and that definitely played a part in our errors. Flying the MAX more frequently would help.
