In 1927, Marín graduated with a Bachelor's degree in Mathematical Sciences from the National University of San Marcos. That same year, he graduated with honours (earning the second highest marks in his class) as a military engineer from the National Architecture School of Versailles, in France.

In 1928, was assigned responsibility to set up an advanced training program for the Peruvian Signals Corp (Spanish: Servicio de Transmisiones), improving the standards for military communications and command and control in the armed forces.

He was a professor at the High Command School of the Air Force of Peru, from its inception, and also of the Peruvian Diplomatic Academy. Marín was a member of the National Academy of Mathematical and Physical Sciences, and president of the Institute of Natives Language.

While he was still alive, Marín was made an honorary professor of the Universidad San Luis Gonzaga.
