About Mason Interactive

Mason Interactive is a data-driven digital marketing agency headquartered in New York City. We deliver integrated, full-funnel media programs that convert consumer insights into measurable business outcomes for national and emerging brands.

Position Overview

This is a senior client leadership role, not a sales role. The Senior Account Executive is the lead strategist and primary client contact for a portfolio of key accounts. You'll own client relationships end to end, set omnichannel media strategy, align senior client stakeholders, and direct cross-functional internal teams to deliver against performance targets and contractual commitments. You'll also mentor Account Executives and be a key driver of account growth.

What You'll Do

• Own relationships with assigned key accounts as the primary point of contact, including senior and executive-level client stakeholders
• Develop and present integrated, multi-quarter media strategies across paid search, paid social, programmatic, affiliate, SEO and AI search (AEO), lifecycle and emerging channels
• Lead status meetings, planning sessions, monthly performance reviews and quarterly business reviews with clear, executive-ready narratives
• Translate performance data into actionable insights and recommendations that guide optimization priorities and future planning
• Oversee budgets, pacing and KPIs across accounts; lead forecasting and budget reallocation recommendations to maximize ROI
• Manage scope, timelines and client expectations; triage change requests and partner with Operations on SOWs and change orders
• Provide strategic direction to planners, buyers and channel specialists; review deliverables for accuracy and strategic alignment
• Identify expansion opportunities and build business cases and proposals that connect client challenges to agency capabilities
• Surface risks early and lead resolution with data-backed options and trade-offs
• Mentor and support Account Executives on client communication, strategy and account management best practices

What You'll Bring

• 5+ years of client-facing digital marketing experience in an agency account management, strategy or media planning role
• Proven success retaining and growing complex accounts while meeting or exceeding KPIs
• Executive presence: confident leading senior-level conversations, managing escalations and influencing decisions with data
• Advanced knowledge of paid search, paid social and programmatic platforms; relevant certifications (Google Ads, Meta, GA4) preferred
• Strong analytical skills, including GA4 and dashboard fluency and the ability to turn large data sets into clear, executive-level narratives
• Financial acumen across budget pacing, forecasting and scope management
• Authorization to work in the United States and ability to work from our Brooklyn office 2–3 days per week

Why Join Mason Interactive

• Direct ownership of strategic initiatives and client outcomes, with a clear path to Account Director and beyond
• Exposure to a diverse portfolio of high-growth clients across multiple verticals
• A collaborative, cross-disciplinary environment that supports rapid testing and implementation of new ideas, including AI-driven search and media
