Your use of too is fine. An alternate word to use instead of too would be the synonym also.
Occasionally, depending on the wording of the sentence, the word too is preceded and followed by a comma, but commas are not necessary in your sentence. In the following sentences, however, the commas would be appropriate, though not necessary:
We think Jack should come along with us, too.
We think Jack should come along with us, too, but his mother disagrees.
Jack's father and older brother, too, are in agreement with his mother.
As the systems we simulate become increasingly complex, the task of validation becomes increasingly complex, too.
Come to think of it, why not omit the word too altogether. I kind of like the sound of,
"As the systems we simulate become increasingly complex, so does the task of validation."
