Senior Growth Marketing Manager, Paid Social

Brex is seeking a Senior Growth Marketing Manager to own, scale, and optimize its Paid Social engine, with Meta as the core growth driver.

The ideal candidate will be accountable for down-funnel pipeline, efficient CAC, and customer acquisition.

Responsibilities:

• Growth & Pipeline Ownership: Own Meta + emerging channel budgets, CAC efficiency, conversion, and downstream pipeline/revenue across self-serve and sales-led motions.
• Signal & Measurement Strategy: Partner with Data and Marketing Ops to improve conversion signals, CAPI, and offline conversion tracking.
• Structured Experimentation: Build and execute a continuous, hypothesis-driven testing framework across audiences, bidding strategies, optimization events, landing pages, and creative concepts.
• Full-Funnel Growth: Build paid social strategies that create demand at the top of the funnel and efficiently convert it through retargeting and lower-funnel programs.
• Creative Strategy: Translate performance data into creative hypotheses and partner with Brand and Design to test, iterate, and scale winning concepts.
• Audience Strategy: Use first-party data, intent signals, modeled audiences, lookalikes, and platform automation to identify and scale high-value audiences.
• Cross-Functional Partnership: Partner with Analytics, Marketing Ops, Field / Events team, PMM, and Sales to connect paid social performance & programs to downstream pipeline and revenue outcomes.

Requirements:

• 5+ years of growth or performance marketing experience, with deep hands-on expertise managing and scaling Meta as a primary acquisition channel.
• Demonstrated experience owning a paid social channel end to end, including strategy, budgets, forecasting, campaign architecture, optimization, and performance reporting.
• Relentlessly analytical: Deep understanding of unit economics (CAC, LTV, payback periods), attribution modeling, and how to connect platform metrics directly to down-funnel business impact.
• Experience running full-funnel paid social programs, from awareness/video and demand generation through conversion and pipeline.
• Strong expertise in audience strategy and platform automation, including first-party audiences, lookalikes, broad targeting, retargeting, and automated campaign products.
• Strong understanding of conversion signals and measurement, including Meta CAPI, server-side tracking, attribution, conversion-event strategy, and CRM/offline conversion data.
