• About Poshmark
• Poshmark is looking for a Growth Marketing Manager, Awareness Media to own our paid video strategy across multiple channels. You will operate with a builder's mindset - testing new opportunities, scaling what works, and managing both direct campaign execution and agency partnerships to accelerate shopper and seller growth.

Responsibilities

• You will own the strategy and execution across our primary video channels: TV, CTV/OTT, and YouTube, with flexibility to explore opportunities like OOH and network partnerships. You will be equally comfortable building a quarterly media plan as you are optimizing live campaigns. Your work will span both sides of our marketplace as needed with a sophisticated mix of in-house execution and agency partnerships. This role will report to the Director of Growth, Awareness.
• Develop and execute Poshmark's integrated video media strategy, balancing brand awareness with intent objectives across TV, CTV, and YouTube
• Own end-to-end campaign execution: planning, media buying, performance monitoring, and optimization across all video channels
• Execute campaigns directly where appropriate (YouTube, programmatic placements) and manage relationships with media agencies for TV, premium CTV, and strategic partnerships
• Collaborate closely with cross-functional partners across brand, creative, data and engineering
• Design and run structured experiments to evaluate channel viability and emerging opportunities - setting clear success metrics and synthesizing learnings into actionable recommendations
• Identify the highest-leverage levers across your channel portfolio - audience, creative, buying strategy - and build scalable playbooks to drive efficiency and scale
• Manage a dynamic budget across channels and time periods, tracking KPIs and translating performance data into clear insights and action plans for stakeholders
• Negotiate rates, added value, and make-goods with networks, platforms, and media partners to maximize efficiency and secure premium inventory
• Collaborate cross-functionally with growth, creative, data, and analytics teams to align media strategy with broader business objectives and quarterly priorities

Requirements

• 5–8 years managing and executing multi-million dollar campaigns across awareness media channels (TV, CTV/OTT, YouTube), ideally at an e-commerce or high-growth brand
• Hands-on-keyboard experience setting up and managing video / CTV campaigns in platforms like CM360, DV360, The Trade Desk, etc.
• Demonstrated ability to manage and optimize multiple channels simultaneously, with a track record of impact through multiple measurement lenses: lift studies, incrementality, MMM, etc.
• Strong negotiation skills and experience securing favorable rates and placements from networks, platforms, and media partners
• Analytical fluency: comfortable working with large datasets, building performance dashboards, and making budget decisions grounded in data
• Experimentation mindset: you know how to design rigorous tests, read results objectively, and deprioritize ideas that are not working
• Comfort with ambiguity: you thrive in environments where focus shifts between seller and shopper initiatives and can adapt without losing momentum
• Excellent written and verbal communication skills with the ability to present channel strategy and results to senior stakeholders clearly
• Strong grasp on media and entertainment trends and calendars within our target audience
