Job description

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.

About the team

The Quality Engineering Team is responsible for the development and implementation of all of Mammoth Brands quality standards, inspection protocols and ALL of the manufacturing processes which includes molding and finished goods production. The team works closely with the Packaging and R&D teams to validate all new component molds and formula production from concept through Mass Production. As we continue to expand into new categories, the Quality team will be an instrumental partner in supporting new exciting innovation and brand success.

About the role

As a Quality Engineering Validation Manager you will lead the development and execution of quality standards, inspection protocols, and validation plans for new Soft Products and Hard Products at Harry’s, Flamingo, Lume, and Mando. You’ll own the validation of new tooling, component development, and finished goods production ensuring we deliver high-quality products that delight our customers. You will work cross-functionally across internal teams and externally with global manufacturing partners to support new product launches, troubleshoot quality issues, and improve both product design and manufacturing processes. This is a high-impact role that sits at the heart of innovation, manufacturing, and customer experience. As we expand our Quality Management System and the Global Quality footprint across the organization, you will have the opportunity to impact our systems and processes, as well as have room for growth and development.

Manage new tooling from pilot through mass production, develop secondary tooling for supply chain capacity, and optimize/standardize manufacturing processes using SPC and quality data.
Own qualification and inspection plans (IQ, OQ, PQ) for both hard and soft product packaging, including fill-line qualification at third-party manufacturers.
Deploy quality tools including process mapping, FMEA, control plans, MSA/GR&R, SPC, and DOE to drive consistency and compliance across the supply chain.
Expand internal and external testing capabilities, draft product/package test plans, and analyze and interpret results to ensure requirements are met.
Lead the commissioning, qualification, validation, and startup of new manufacturing and packaging equipment from Factory Acceptance Testing (FAT) through Site Acceptance Testing (SAT) and commercial production.
Conduct supplier audits, manage CAPAs, monitor performance metrics, and ensure suppliers meet Mammoth Brands' quality standards during both launch and ongoing production.
Lead failure analysis and root cause investigations, driving effective CAPA to resolve quality issues and prevent recurrence.
Evaluate technical risks using tolerancing and stack-up analysis, and develop clear mitigation plans in partnership with R&D and Supply Chain.
Support advanced product quality planning to ensure smooth integration of new products into operations, owning finished goods specifications.
Serve as the voice of the customer across product development, partnering with R&D, Package Engineering, and suppliers to design quality in while improving manufacturability and reducing costs.
Participate in program retrospectives and lead ongoing initiatives to improve quality, efficiency, and supply chain performance.
Travel (Domestic and International), up to 40%.
