Barangay officials in the Philippines are elected during the synchronised Barangay and Sangguniang Kabataan Elections (BSKE). Reymundo currently holds office under the mandate established by the October 30, 2023 BSKE. The next BSKE, at which this position will again be contested, is scheduled for Monday, November 2, 2026.

A Philippine barangay's Sangguniang Barangay is composed of one Punong Barangay, seven Sangguniang Barangay Members (kagawads), a Sangguniang Kabataan (SK) Chairperson representing the youth sector, a Barangay Secretary, and a Barangay Treasurer. Together, these officials administer the smallest unit of Philippine local government and deliver frontline services — from barangay clearance issuance to peace and order, from public health assistance to the barangay's share of the Internal Revenue Allotment.
