These are just the first two that popped into my head. If I cared to actually research it I’m sure I’d find a lot more.

To name an old example… Margaret Hamilton who is credited with coining the term ‘Software Engineering’ and helped write the flight control software for the Apollo Moon missions.

A more recent example would be Katie Bouman who helped develop the CHIRP algorithm that took an absolutely massive amount of data from radio telescopes to generate an image of a black hole.
