Brex is seeking a strategic, data-driven Growth Marketing Lead to own and shape the company's investment across programmatic display, YouTube, CTV, online video, audio, and emerging digital channels. This is a high-visibility role reporting into the Marketing leadership team at a leading fintech platform used by tens of thousands of companies globally.
You will own a significant media portfolio spanning both Brand and Growth initiatives, with responsibility for defining how these programs work together, proving incremental impact, and identifying where Brex should invest next. Your core mandate is to combine deep programmatic expertise with strong measurement, audience strategy, and experimentation instincts to drive smarter investment decisions and scalable growth. A key aspect of this role is building brand through a performance lens—connecting upper-funnel awareness investments to near-term conversion impact and long-term value creation.
Key responsibilities include: owning strategy, investment, and performance across programmatic display, video (CTV, OLV, YouTube), audio, and emerging channels; evolving Brex's media operating model and partner ecosystem through DSP/vendor evaluation, agency management, and development of scalable processes; building integrated audience strategies using first-party data, intent, contextual, modeled, and third-party signals; developing a comprehensive measurement framework in partnership with Analytics and Data Science teams to track attribution, incrementality, and brand lift; partnering cross-functionally with Brand, Product Marketing, and Design teams to translate campaign objectives into media strategy and creative requirements; identifying emerging channels and AI-enabled opportunities for quarterly and annual planning; and establishing governance and operating standards across programmatic media including QA and risk controls.
You bring 7+ years of hands-on growth or performance marketing experience with deep expertise in programmatic media and video/CTV advertising. You have demonstrated success owning multi-channel media portfolios with significant budgets, including investment planning, forecasting, optimization, and scaling decisions. You possess deep knowledge of the programmatic ecosystem and major DSPs (DV360, The Trade Desk, etc.), including bidding strategies, inventory management, audience architecture, and vendor management. You understand full-funnel B2B marketing and can connect awareness and consideration investments to downstream business outcomes. You are fluent in measurement, attribution, and incrementality testing, including experimentation design, lift studies, and geo/holdout tests. You can build sophisticated audience architectures leveraging first-party, contextual, intent, modeled, and third-party data signals. You have strong creative judgment and experience partnering effectively with Brand and creative teams.
The role is based in Brex's Seattle office with a hybrid work model requiring three days per week in-office (Mondays, Wednesdays, Thursdays), plus flexibility to work remotely up to four weeks annually.
