We hire people who enjoy solving difficult business problems, thinking strategically, and building systems that scale. Description The Opportunity: Rubix is entering its next chapter. We're hiring a Growth Marketing Manager to own client relationships and growth strategy across a portfolio of consumer brands. This person will sit at the intersection of business strategy, paid media, creative, and analytics - leading the client conversation while bringing deep expertise in Meta. This is not a traditional media buying role. The Growth Marketing Manager will understand the economics of the business, develop a point of view on what is driving performance, and turn that thinking into clear recommendations for clients and the Rubix team. The right person will be equally comfortable inside an ad account, reviewing a creative roadmap, and explaining what the numbers mean to a founder or marketing leader. What You'll Lead: Own the day-to-day relationship for a portfolio of Rubix clients. Lead performance meetings, account plans, reporting, and strategic recommendations. Build trust through direct communication, good judgment, and a willingness to say what the business needs - even when the answer is not simply to spend more. Meta strategy and performance Set the strategy and performance bar for Meta. Evaluate account structure, budgets, audiences, offers, testing, and creative performance. Know when to work inside the platform and when to step back and diagnose a broader problem across the customer journey. Business economics and measurement Ground decisions in the actual financials of the business: CAC, new customer CAC, contribution margin, LTV, payback, cohorts, incrementality, and blended performance. Help clients see past platform-reported results and understand what is truly driving profitable growth. Creative strategy and iteration Partner with the creative team to turn performance signals into useful briefs, testing roadmaps, and clear feedback. Understand how hooks, offers, formats, landing pages, and merchandising work together - and help the team focus on the creative opportunities most likely to change the outcome. Meta will be your deepest channel, but the client needs an integrated point of view. Work across paid search, lifecycle, analytics, SEO/AEO, and affiliate / PR to understand the full growth picture. Collaborate with channel experts and make sure the work adds up to one coherent client strategy. AI as operating leverage Rubix is actively exploring how AI can make the agency sharper, faster, and more consistent. Use AI-enabled workflows across research, reporting, analysis, creative iteration, documentation, and client communication. This requires curiosity, pragmatism, and the judgment to know what should - and should not - be automated. Who You Are: You have performance marketing experience and have helped grow consumer brands, ideally in an agency environment. You've owned client relationships, managed meaningful paid media budgets, and know how to connect channel performance to the economics of the business. You also believe AI is going to reshape what a great agency looks like, and you want to be in the room where that gets built. You bring 5-8 years of growth or performance marketing experience, ideally with DTC, ecommerce, or omnichannel consumer brands Deep Meta expertise and a track record managing meaningful budgets against revenue and acquisition goals Fluency in CAC, new customer CAC, contribution margin, LTV, cohorts, payback, incrementality, and blended performance Experience leading client calls, presenting recommendations, and earning trust with founders and marketing leaders Strong creative instincts and experience translating performance data into creative testing priorities Working knowledge of Google Ads and the ability to collaborate effectively across search, lifecycle, analytics, and other growth channels Fluency and passion for leveraging AI Bonus: experience operating an ecommerce business, working with subscription models, or supporting omnichannel CPG brands You are Commercially minded: you understand that the job is to drive measurable business outcomes, not simply improve platform metrics Direct, clear, and able to debate and discuss respectfully Analytical without losing the larger strategic picture A proactive communicator who builds trust through follow-through Clear about ownership, deadlines, and impact Comfortable in a founder-led, high-trust environment where clients depend on you How We Work: Rubix is remote-first with a New York office. Most leadership is on the East Coast, and several key client relationships involve in-person meetings periodically. East Coast-based candidates are preferred, though exceptional candidates elsewhere will be considered with the expectation of some travel. The team operates on Slack, ClickUp, Google Workspace, and Granola for meeting capture. You should be fluent, pragmatic, and ambitious about what AI can do for an agency. About Rubix: Rubix is a performance marketing agency built for the next chapter of consumer growth. We help high-velocity brands scale through paid media, performance creative, lifecycle, SEO/AEO, analytics, and affiliate / PR - working with clients like FreshDirect, Fishwife, PetMeds, Mountain House, and Kosterina to drive measurable business outcomes. We're profitable, growing 50%+ annually, and known for the quality of our thinking, the depth of our client partnerships, and a team that consistently delivers ahead of its size. We're also excited about how AI can further expedite our growth and allow us to be strategic partners for the brands we represent.
