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.” Everything we do should be better than what already exists. This guides our product development, workplace culture, and community initiatives.

About The Team

The Quality Engineering Team is responsible for the development and implementation of all Mammoth Brands quality standards, inspection protocols, and manufacturing processes, including molding and finished goods production. The team collaborates closely with Packaging and R&D to validate new component molds and formula production from concept through mass production. As we expand into new categories, the Quality team plays an instrumental role in supporting innovation and brand success.

Responsibilities

• 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%.
