Senior Associate, Media Strategy (MIA)

Location: Miami, Florida strongly preferred
Employment Type: Full-time
Compensation: $80,000–$92,000 base salary, plus opt. performance-based bonus
Work Authorization: Candidates must be legally authorized to work in the United States.

The Role

We are seeking a curious, analytical, and highly organized Media Strategist with a minimum of three years of media agency experience.

This is not an entry-level role.

The successful candidate will already understand how a media agency works and will have experience contributing to real client assignments, media plans, campaign analysis, research, reporting, budget development, or activation. We are looking for someone ready to move beyond task execution and develop into a stronger strategic thinker.

The Media Strategist will work across client teams and media channels, supporting the development of media strategies, audience recommendations, channel plans, market analyses, competitive reviews, campaign reporting, and post-campaign learning.

Because our work frequently crosses markets, cultures, languages, and media environments, multilingual candidates and candidates with international experience are especially encouraged to apply.

Responsibilities

Media Strategy and Planning

Support the development of media strategies that connect business objectives, audience behavior, geography, channel roles, investment levels, and measurement.

Conduct research into audiences, markets, competitors, media consumption, platforms, publishers, and emerging opportunities.

Help translate research into clear strategic implications and recommendations.

Assist with media mix development, budget allocation, scenario planning, reach and frequency considerations, and geographic investment decisions.

Create and maintain media plans, flowcharts, planning documents, budget trackers, and supporting strategic materials.

Develop media POVs and research briefs on new channels, platforms, technologies, audiences, and market developments.

Reporting and Analysis

Work with activation and analytics teams to understand campaign results and identify meaningful patterns.

Contribute to campaign reporting that explains what worked, what did not, why performance changed, and what should happen next.

Develop clear charts, tables, summaries, and written insights for client-facing materials.

Compare performance across markets, channels, audiences, placements, formats, and time periods.

Help distinguish useful evidence from incomplete or misleading signals.

Account and Team Support

Work closely with senior account, strategy, performance, buying, and ad operations teams.

Participate actively in internal planning sessions and client meetings.

Prepare meeting materials, document decisions, and help ensure that agreed next steps are completed.

Coordinate with media vendors and partners as needed to gather research, specifications, inventory information, proposals, and campaign documentation.

Help maintain quality and accuracy across budgets, timelines, plans, presentations, and reports.

Take increasing ownership of defined workstreams as experience and capability grow.

What We’re Looking For

Minimum of 3 years of full-time experience at a media agency, advertising agency with substantial media responsibilities, or comparable media planning organization.

Experience supporting or developing paid media strategies and plans.

Understanding of the major media channels, including several of the following: paid search, paid social, programmatic, CTV, digital video, display, OOH, television, audio, print, sponsorship, or retail media.

Strong analytical skills and comfort working with campaign data and spreadsheets.

Strong PowerPoint or Slides or AI-based presentation-development skills. The format matters less than the skill.

Excellent writing, editing, and communication abilities.

High attention to detail and the ability to manage multiple assignments simultaneously.

Curiosity about business, consumer behavior, culture, technology, and media.

A desire to understand why a media recommendation makes sense—not simply how to complete the planning template.

Experience with international campaigns or multi-market planning is strongly preferred.

Professional proficiency in a language other than English is highly valued.

The Person Who Will Thrive Here

You ask good questions.

You notice inconsistencies.

You are interested in what the numbers mean, not simply whether the spreadsheet balances.

You like learning about unfamiliar industries, markets, audiences, and business models.

You can take direction, but you also begin thinking independently about the problem behind the assignment.

You write clearly, work carefully, and take deadlines seriously.

Most importantly, you want to become genuinely good at media strategy—not simply move through agency titles as quickly as possible.
