Looking for Backup Character ideas: level 10 To 15

[JuliusCromwell]

I am in a pathfinder version of 5e's Rise of Tiamat and want a couple of back up character ideas in case my current one ends up biting the dust.

I'd like to be useful to the party and fill a role or two we don't have

We are a party of 4 consisting of
An Alchemist with a fly speed
An oracle with physical Exemplar archetype
A path of war Medic. Unsure of Archtype
And myself a Human Archer (Fighter)

If my Archer dies what would be some good choices to fit in this party?

Eldritch Archer Magus... adds some arcane casting, but doesn't get rid of archery. Having an archer in the party is always nice. Arsenal Chaplain Warpriest can do gods work with archery, too. So can Inquisitors... if either of those classes interest you more than a Magus.
