The Villainess is an Engineer

When a Nobleman's daughter Isla Villin, attempts to win the attention of Alexandar Starling, by drinking a love potion, needless to say she did not gain the object of her envy. Instead, she remembers her past life as a broke engineering student on Earth. In a place of fantasy and low-tech, she must use her engineering abilities to navigate the magic systems and avoid the death of the Villainess archetype.
