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. 

About the team 

The Growth Marketing team at Lume & Mando is a fast-moving, data-driven group that owns the development and execution of paid media strategy across our key marketing channels. The work we do is central to growing the business across all channels, and we partner closely with creative, finance, planning, and others in order to drive new customer acquisition and stay on the cutting edge of digital strategy, consumer trends, and business needs.

 

About the role

We are looking for a highly analytical, high-ownership Growth Marketing Associate to join our team and play a direct role in scaling Mammoth Brands and Lume/Mando. This is a high impact position with real decision making power. You will manage meaningful budgets across our core digital channels including Meta, Google, TikTok, Reddit, and more, and you will see the immediate revenue impact of your work.

This role is ideal for someone early in their career who wants to learn fast, think deeply, and take responsibility. We care far more about how you think than where you have worked. Whether your background is in performance marketing, consulting, finance, analytics, or another quantitative field, what matters is your ability to dig into data, find the “why,” and turn insight into action. You will work closely with senior growth leaders, gain exposure to how a scaled consumer business drives growth, and quickly grow into broader strategic ownership.

 

What you will accomplish

  • Own Strategy and Budgets: You will own the day to day strategy and execution of paid media campaigns across multiple platforms. This includes setting channel strategy, allocating budgets, launching campaigns, and making real time decisions that directly affect company growth.
  • Optimize Performance in Real Time: You will monitor performance daily, diagnose what is working and what is not, and proactively adjust strategy to improve efficiency and scale. You will be trusted to make calls based on data, not just follow a playbook.
  • Shape Creative Direction: You will partner closely with our creative team and use performance data to influence what we make next. You will turn insights into clear creative briefs for new videos, images, and copy and see those ideas tested quickly.
  • Testing & Experimentation: Design and run rigorous A/B tests—from landing pages to bidding strategies—to uncover new growth opportunities.
  • Translate Data Into Insight: You will build clear, actionable reporting that helps leadership understand what is driving growth, where we are winning, and where we need to pivot. Your analysis will directly inform strategic decisions.

This should describe you

  • Analytical & Data-Driven: You are comfortable living in Excel or Google Sheets. You don’t just report on numbers, you understand what they mean, how they relate to each other, and how to use them to make better decisions.
  • Proactive Problem Solver: You don’t wait for a playbook. When a campaign isn't performing, you enjoy the "detective work" required to find a solution.
  • High Ownership: You take extreme pride in your work. You are a self-starter who moves fast and hits deadlines without needing to be micro-managed.
  • Clear Communicator: You can explain complex ideas simply and are comfortable collaborating across different teams like Creative, Product, or Finance.
  • Flexible & Adaptable: You know how to pivot in the face of the unexpected, aren’t overly attached to preconceived notions when presented with new information or a lack thereof, and can navigate ambiguity gracefully.

Qualifications

  • Experience: 1–3 years of experience in a fast-paced, high-intensity environment (e.g., Management Consulting, Finance, or Performance Marketing).
  • Education: Bachelor’s degree in a quantitative or business-related field (Economics, Finance, Science, Engineering, Math, etc.).
  • Technical Proficiency: Advanced skills in Excel/Google Sheets are a must.
  • Mindset: A strong desire to learn the mechanics of growth marketing and a "no task too small" attitude. We are a small team, so scrappiness and teamwork are the baseline.

While we are happy to train the right candidate, familiarity with the following tools and concepts is a plus:

  • Paid Media Platforms: Experience and familiarity with Meta Ads Manager and Google Ads Manager, including navigation, tools, best practices, etc. 
  • Analytics Tools: Basic exposure to Google Analytics 4 (GA4), Looker, or similar data platforms.
  • Marketing Math: Understanding of core digital metrics such as CAC, LTV, ROAS, CPM, CTR, etc.

Here's who you'll work with

  • Reporting to the Senior Growth Marketing Manager
  • Working on the Growth Marketing team
  • Working cross functionally with Creative, Finance, Web, Retail, and more.
