Senior Manager, Paid Social (B2B) (Freelance)

Who We're Looking For  

As a member of the Media Freelance Team at Marketbridge, the Senior Manager, Paid Social will lead paid social strategy and execution across a portfolio of B2B client accounts.  

This role is designed for someone who has strong hands-on paid social expertise but is ready to operate at a broader level. You’ll manage more complex client programs, oversee multiple accounts with different goals and audiences, guide campaign strategy and optimization, and help clients understand how paid social supports their broader demand generation, ABM, pipeline, and revenue goals.  

You’ll remain close to the platforms and should be comfortable stepping into campaign setup, QA, troubleshooting, and optimization when needed. However, success at this level comes from your ability to see the bigger picture, set direction, guide others, and make sound strategic decisions across accounts.  

Our team contributes by providing strategic guidance to clients and internal teams around how paid social can solve complex marketing challenges. We are also actively involved in business development, organic growth, and shaping media recommendations for both current and prospective clients.  

You Must Be 

Nimble: You can ramp up quickly on new accounts and move across several clients, priorities, and platforms without losing quality or attention to detail. 

Collaborative: You work easily alongside our in-house Media, Demand Strategy, Creative, Analytics, Client Success, and Project Management teams, and fit into existing workflows from day one. 

Curious: You keep learning and look for better ways to work, including thoughtful use of AI and emerging tools to improve strategy, analysis, and efficiency. 

Strategic: You look beyond individual campaigns and connect paid social decisions to broader audience, demand generation, ABM, and business goals. 

Proactive: You anticipate what clients and teams will need, bring recommendations without being asked, and challenge the expected when there’s a stronger path forward. 

Detail Driven: You work at a strategic level while staying close to the campaign details that affect performance. 

A Strong Communicator: You simplify complex media performance and explain recommendations clearly to clients and internal stakeholders, including clear handoffs and status updates as a remote contributor. 

Self-Directed: You manage your own time, deliverables, and deadlines with minimal oversight, and you flag risks or capacity constraints early. 

What We’re Looking For 

We’re looking for an experienced freelance paid social strategist to lead paid social strategy and performance across select B2B client accounts. You’ll work as an extension of our Social team, bringing senior-level expertise to client programs on a flexible, engagement-based basis.
