Senior Growth Marketing Manager, Paid Social

The Marketing team tells the Brex story — turning product innovation into customer obsession. We develop messaging, shape the brand, and bring our platform to life through thoughtful, compelling content. Our team spans Revenue Marketing, Product Marketing, and Brand Marketing, and works cross-functionally with Product, Sales, Business Development, and Design to drive growth and build trust.

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.

This role will be based in our Seattle 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.
