What you'll do

• Brex is seeking a deeply analytical, growth-rooted Senior Growth Marketing Manager to own, scale, and optimize our Paid Social engine, with Meta as the core growth driver and a clear mandate to test and scale emerging channels.
• In this role, you will be accountable for down-funnel pipeline, efficient CAC, and customer acquisition.
• You won't just optimize campaigns; you will engineer signal architecture, build scalable audience models, and establish a high-velocity creative testing engine.
• Critically, you know how to build brand through a performance lens, connecting upper-funnel investments to near-term impact and long-term value creation.
• You'll help accelerate Brex's growth by scaling what works, continuously improving how we operate, and unlocking new opportunities for impact.

Where you'll work

• This role will be based in our San Francisco office.
• We are a hybrid environment that combines the energy and connections of being in the office with the benefits and flexibility of working from home.
• Team members are expected to work in-office three days per week (Mondays, Wednesdays, and Thursdays).
• Brex also offers the flexibility to work remotely for up to four weeks per year, in one-week increments.

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, enabling platforms to optimize toward higher-quality customers.
• Structured Experimentation: Build and execute a continuous, hypothesis-driven testing framework across audiences, bidding strategies, optimization events, landing pages, and creative concepts; document learnings to turn paid social into a predictable acquisition channel.
• 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.
• Demonstrated experience building structured experimentation roadmaps across creative, audiences, bidding, optimization events, and new platform capabilities.
• Strong creative judgment and experience writing briefs and translating performance data into actionable creative recommendations.
• Excellent communicator who can operate autonomously and influence cross-functional partners across Brand, PMM, Design, Analytics, Engineering, Marketing Ops, and Sales.
