It is a now a high paying job.
The movie Hidden Figures shows that it was originally women's work, as they made the transition from human calculators to computers. Or even earlier with the ENIAC.
During World War II, while the U.S. Army needed to compute ballistics trajectories, many women were interviewed for this task. At least 200 women were hired by the Moore School of Engineering to work as "computers"[23] and six of them were chosen to be the programmers of ENIAC. Betty Holberton, Kay McNulty, Marlyn Wescoff, Ruth Lichterman, Betty Jean Jennings, and Fran Bilas, programmed the ENIAC to perform calculations for ballistics trajectories electronically for the Army's Ballistic Research Laboratory.[46] While men having the same education and experience were designated as "professionals", these women were unreasonably designated as "subprofessionals", though they had professional degrees in mathematics, and were highly trained mathematicians.[46]from Wikipedia
