About Mammoth Brands

Mammoth Brands (formerly Harry’s Inc.) is the modern CPG company behind brands Harry’s, Flamingo, Lume, Mando, and Coterie. We’re building a new model—and home—brands, founders, and talent looking to solve unmet needs, improve peoples’ lives, and ultimately challenge the status quo. Our mission is to “Create Things People Like More.” Simply put: everything we do should be better than what already exists. If it’s not, we don’t do it. This guides everything we do, from developing the best product experiences, to making Mammoth Brands a great place to work, to exploring innovative ways to give back to our community.

We got our start in 2013 when our co-founders created Harry's. They built the brand differently—online first, prioritizing direct relationships with customers—and in the process learned they’d created something bigger: a playbook and platform that could help other brands grow and scale to their full potential, and a vision to reimagine consumer packaged goods. Today, Mammoth Brands is a growing portfolio of brands and the largest CPG company built in the last 20 years. Even as we grow, we take extra care to maintain the small, scrappy, entrepreneurial culture that helped to get us where we are today: to create a company that people like more, that better serves its customers, employees, and community. As a company, we’re also committed to making a positive impact and have donated over $20 million through our network of nonprofit partners to date.

We build brands that move fast and think big — and we hire people who are curious about AI, willing to experiment with it in their day-to-day work, and excited to accelerate what's possible. We prioritize giving our team the tools, training, and space to build real fluency, so you grow alongside the technology and help shape how we use it.

Here's what you'll do

Serve as a strategic thought partner to Marketing, Finance, and Executive Leadership, helping shape business decisions
Own the analytical inputs, methodologies, and decision frameworks that inform high-impact cross-functional processes including marketing budget allocation, demand planning, and financial forecasting.
Lead the interpretation of Marketing Mix Models (MMM), incrementality studies, and other attribution methodologies to develop a holistic view of marketing performance.
Advise leaders on the strengths, limitations, and appropriate application of different marketing measurement approaches, ensuring decisions account for uncertainty rather than false precision.
Translate complex and imperfect data into clear, compelling narratives that drive alignment and action across technical and non-technical stakeholders.
Partner closely with Marketing, Finance, and Analytics teams to evaluate investment opportunities, identify growth drivers, and recommend where incremental marketing dollars should be deployed.
Develop hypotheses, pressure-test assumptions, and proactively identify opportunities and risks
Build lightweight analytical models, scenarios, and "napkin math" to rapidly evaluate business decisions and communicate tradeoffs.
Champion measurement best practices while balancing analytical rigor with the realities of making timely business decisions.
Become a trusted advisor across the organization on marketing measurement, attribution, forecasting, and marketing performance.

Background & Experience

Significant experience in marketing analytics, marketing attribution, growth analytics, or marketing strategy.
Deep expertise with Marketing Mix Modeling (MMM), incrementality, and modern marketing attribution methodologies.
Strong understanding of the tradeoffs, assumptions, and limitations of various attribution approaches, and the judgment to know when each should (or should not) be used.
Strong business acumen and familiarity with the metrics that drive executive decision-making, including:

Marketing KPIs (ROAS, ROI, CPM, CPC, CPA, incrementality, etc.)
Financial KPIs (gross revenue, net revenue, gross margin, contribution margin, EBITDA, profitability)
Business KPIs (LTV, CAC, LTV:CAC, AOV, retention, payback period, customer economics)

Solid understanding of statistics and uncertainty in marketing measurement. While this is not a data science role, you should be comfortable discussing statistical concepts with technical partners and incorporating uncertainty into recommendations.
Exceptional communication skills with the ability to simplify complex analyses into compelling business narratives and actionable recommendations.
Highly proficient in Google Sheets and comfortable building quick analyses, business cases, forecasts, and decision models without relying on sophisticated tooling.
Experience working cross-functionally with Marketing, Finance, and Executive Leadership.
Programming experience (SQL, Python, R, etc.) is not required, though SQL experience is valuable. This role is focused on business leadership and analytical judgment rather than data engineering or model development.

Values that might describe you

You naturally think like an owner and proactively identify opportunities instead of waiting for direction.
You have conviction, but not ego. You're willing to form opinions, make recommendations, and commit to decisions while remaining open to changing your mind when new evidence emerges.
You are comfortable making decisions with imperfect information and understand that uncertainty is an unavoidable part of marketing measurement.
You value action over analysis paralysis and recognize that a timely 80% answer is often more valuable than a perfect answer delivered too late.
You enjoy challenging assumptions—including your own—and are comfortable respectfully pushing back when the data tells a different story.
You care more about helping the business make better decisions than about being "right."
You communicate with clarity, influence through trust, and know how to tailor your message for executives, marketers, finance partners, and technical teams alike.
You are intellectually curious and constantly seek to improve how the organization measures, understands, and invests in growth.
