About The Position

The Junior Media Buyer is an entry-level position within the Media Department, designed for candidates who are beginning their careers in media buying and want to build a strong operational foundation in traditional media. This role supports the Media Buyer and Head of Media Investment in the execution, documentation, and tracking of approved media buys — learning the craft of media buying through hands-on work with real campaigns, real budgets, and real vendor relationships. The Junior Media Buyer is expected to be detail-oriented, organized, and eager to learn. While this role operates with supervision and guidance from the Media Planner, it carries genuine responsibility — accuracy in documentation, budget tracking, and vendor communication matters from day one. Mistakes in rates, placements, or invoices have real consequences, and the Junior Media Buyer is expected to approach every task with precision and professional accountability. This is a deliberate growth role with a clear path to Media Buyer. The agency is committed to developing this person's skills, and the expectation is that they will grow into full buying responsibility over time.

Requirements

Attention to detail: Catches errors in rates, placements, schedules, and invoices before they escalate — accuracy and thoroughness are the most important qualities in this role.
Organizational discipline: Keeps files, trackers, and documentation current, organized, and easy for others to navigate — never lets tasks fall through the cracks.
Numerical comfort: At ease working with budgets, rates, and billing figures — able to spot when numbers don't add up and escalate with the right context.
Eagerness to learn: Approaches new tasks with curiosity and initiative — asks good questions, follows through on feedback, and actively builds their media buying knowledge every day.
Communication: Communicates clearly and professionally in written and verbal interactions — with vendors, the Media Planner, and internal team members.
Reliability: Meets deadlines, follows through on commitments, and flags issues early rather than late — the team depends on this role to be a consistent and dependable operational contributor.
Solid proficiency in Microsoft Office — particularly Excel for tracking, data entry, and basic budget management.
Strong mathematical ability for rate calculations, budget reconciliation, and invoice verification.
Ability to learn media buying, traffic management, or campaign tracking platforms quickly.
Comfortable managing and organizing digital files, documents, and records with consistency and accuracy.
Excellent written and verbal communication in both English and Spanish.
Strong follow-through — able to track multiple open items simultaneously and ensure nothing is left unresolved.
Professional and respectful in vendor and internal communications from day one.
Demonstrated integrity in handling confidential budget, rate, and client information.
Comfortable asking for help and escalating issues to the Media Planner when needed — knowing when to act independently and when to check in is a key skill at this level.
