One who executes or carries out something; an alternative (though less common) form of 'executor'.
From Late Latin executor, from Latin exsequi (to carry out, follow to the end). The -er suffix creates an agent noun. This is an older spelling variant of 'executor.'
While 'executor' is the standard legal term for someone managing an estate, 'executer' appears in older texts and shows how English spelling wasn't standardized until relatively recently—even job titles had multiple accepted spellings!
