Castañeda was born in Los Angeles, but raised in Sinaloa, Mexico. He returned to the United States where he attended high school when he was 14. Castañeda initially studied civil engineering in college with the intention of taking over the family business after he finished his studies. However, he became interested in film direction, and switched to major in film production and international business at California State University, Fullerton, where he had attended since 2007. Castañeda then moved into acting and started auditioning for roles. He studied part-time while pursuing an acting career, eventually graduating in 2015.
Castaneda has been involved in acting since he was 17, but only took acting more seriously after he volunteered for a role when a director asked for actors to participate in his film during a seminar while at university. He played various minor roles in a number of productions, such as End of Watch, and also acted as a main character in a short film Maddoggin', which won the audience award at the NBC Universal Short Cut Film Festival. In 2013, he landed a role playing Jorge on ABC Family's TV series Switched at Birth. In late 2016, he was cast in the role of Hector in the film Sicario: Day of the Soldado released in 2018. He also has a lead role in an independent film El Chicano, a supporting role in Jean-Claude Van Damme's We Die Young as well as minor roles in films such as the Billy Crystal's film Standing up, Falling Down.
