Brijesh started his political career as a leader of the student wing of the RSS, the Akhil Bharatiya Vidyarthi Parishad, in 1994.

Later he became an activist in BJP's youth wing Bharatiya Janata Yuva Morcha (BJYM) and gradually rose in the BJYM hierarchy, holding various posts including that of District Secretary, District Vice president, Vice-Incharge, and Incharge of West Uttar Pradesh and vice-president of the State.

In 2016, Brijesh was given a strategic post in BJP and appointed Secretary for West UP considering the upcoming Legislative Elections in the state.

He was given a ticket from the controversial seat of Deoband, in Uttar Pradesh General Elections 2017 which the party hasn't won since 2002.

Brijesh secured a thumping victory over the rivals from Deoband which made him a favorite among the party's top brass and Uttar Pradesh's politics.
