Part-Time Senior Accounting Associate

About the Company

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—for 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 from developing the best product experiences to making Mammoth Brands a great place to work.

Founded in 2013 with Harry's, we built the brand differently—online first, prioritizing direct customer relationships. Today, Mammoth Brands is a growing portfolio of brands and the largest CPG company built in the last 20 years. We maintain a small, scrappy, entrepreneurial culture while creating a company that better serves its customers, employees, and community. We’ve donated over $20 million through our nonprofit partners and are committed to making a positive impact.

We build brands that move fast and think big, hiring people curious about AI, willing to experiment with it, and excited to accelerate what's possible. We provide tools, training, and space to build fluency in AI, helping you grow alongside the technology.
