This is a bit of a stretch but it may be the Craft Sequence by Max Gladstone (specifically the first book, Three Parts Dead).
A god has died, and it’s up to Tara, first-year associate in the
international necromantic firm of Kelethres, Albrecht, and Ao, to
bring Him back to life before His city falls apart.
Her client is Kos, recently deceased fire god of the city of Alt
Coulumb. Without Him, the metropolis’s steam generators will shut
down, its trains will cease running, and its four million citizens
Tara’s job: resurrect Kos before chaos sets in. Her only help:
Abelard, a chain-smoking priest of the dead god, who’s having an
understandable crisis of faith.
When Tara and Abelard discover that Kos was murdered, they have to
make a case in Alt Coulumb’s courts—and their quest for the truth
endangers their partnership, their lives, and Alt Coulumb’s slim hope
Set in a phenomenally built world in which justice is a collective
force bestowed on a few, craftsmen fly on lightning bolts, and
gargoyles can rule cities, Three Parts Dead introduces readers to an
ethical landscape in which the line between right and wrong blurs.
Tara can perform necromancy, maybe other types of magic (I can't remember off hand) and she has a friend, Abelard, who is a kind of engineer/monk.
The university Tara graduates from is in the sky and she almost gets thrown out (literally) just before graduation.
