Sr. Director, Acquisition Marketing

Responsibilities

• Own the acquisition function and its strategy
• Set the multi-year vision and operating strategy for paid acquisition, and translate it into annual plans, targets, and investment decisions the business can hold you to
• Own full accountability for a seven-figure monthly media budget, including allocation across markets and channels, in-year reforecasting, and the tradeoff decisions that come with it
• Own acquisition performance against growth and efficiency targets, with deep fluency in CPA, CAC, lifetime value, payback period, and marginal CAC analysis
• Serve as the acquisition voice on the Marketing leadership team and present performance, strategy, and investment cases directly to the executive team
• Define how acquisition is planned, measured, and governed at NinjaTrader, setting standards other marketing functions build against
• Build international from a standing start
• Own the buildout of paid acquisition across Europe and rest of world end to end, from market prioritization and entry sequencing through launch and scale
• Determine the operating model for each market — in-house versus agency, channel mix, localization approach, and the economics that justify entry
• Build the partnerships, vendor relationships, and internal capability required to run acquisition outside the US

Requirements

• 12+ years of experience in growth or performance marketing, ideally in D2C subscription-based or fintech businesses, including significant time leading teams
• Demonstrated ownership of a paid acquisition function at scale, with accountability for budget, team, and results rather than execution of a defined plan
• Proven experience building paid acquisition in new international markets from the ground up, including market selection, operating model decisions, and navigating local regulatory requirements
• Track record managing seven figures or more in monthly media spend with strong unit economics
• Deep expertise across web and mobile paid channels, including Google, Meta, YouTube, programmatic, influencer/affiliate, iOS, and Android
• Strong command of CAC, LTV, ROAS, payback period, incrementality, and media mix modeling, with hands-on experience partnering with Analytics and Data Science on attribution design and predictive cohort modeling
• Experience building and developing a marketing team, including hiring, structure, and progression
• Experience owning agency and platform partner relationships, including commercial negotiation and performance management
• Executive presence, with a track record presenting strategy and performance to senior leadership and defending investment decisions
• Exceptional reporting and data storytelling, with the ability to move from raw data to a narrative an executive can act on

Preferred

• Previous experience in B2C marketing for fintech companies
• Previous experience in the futures or brokerage industry
• Experience running paid and organic as one combined growth system rather than separate channels
• Experience scaling a function through a period of rapid international expansion
