Core Responsibilities

Primary Functions

Spearhead the research, development, and commercialization of new and innovative yarns, from initial concept and fiber selection through to bulk production feasibility.
Manage the end-to-end yarn development lifecycle, creating detailed technical specifications, and overseeing sample development to ensure alignment with design intent and quality benchmarks.
Lead the global sourcing strategy for all yarn categories, identifying, evaluating, and onboarding new mill partners to enhance innovation, quality, and supply chain diversification.
Establish and maintain a comprehensive physical and digital yarn library, ensuring it is current, well-organized, and serves as an inspirational and functional resource for the design and product teams.
Drive all aspects of yarn quality assurance, defining testing protocols (e.g., AATCC/ASTM standards for strength, pilling, colorfastness) and making critical decisions on bulk yarn approval.
Act as the primary technical liaison between internal teams (Design, PD, Production) and external yarn suppliers, effectively communicating requirements and troubleshooting issues.
Manage the yarn color development process, overseeing lab dip submissions, evaluating color under various light sources, and providing clear, decisive feedback for approvals.
Conduct rigorous risk assessments on new and existing yarns, analyzing potential performance issues and developing mitigation strategies to prevent production failures.
Negotiate costing and lead times with yarn mills, leveraging market knowledge and strong supplier relationships to achieve business targets without compromising quality.
Champion material sustainability initiatives by researching and promoting the use of recycled, organic, and other environmentally preferred fibers and processes (e.g., GRS, OCS, RWS).
Travel internationally and domestically to supplier facilities for R&D meetings, new development kick-offs, quality audits, and production troubleshooting.
Analyze and interpret yarn testing data and reports, translating complex technical information into actionable insights for non-technical stakeholders.
Create and maintain meticulous records and data within the Product Lifecycle Management (PLM) system for all yarn specifications, costs, and supplier information.
Proactively research and present findings on emerging yarn trends, new fiber technologies, and manufacturing innovations to keep the brand at the forefront of the industry.
Collaborate directly with garment technical designers to troubleshoot and resolve issues where yarn characteristics impact garment construction, fit, or performance.
Develop and implement yarn performance standards across all product categories, ensuring consistency and adherence to brand quality expectations.
Partner with the compliance team to ensure all sourced yarns meet global regulatory standards, including RSL (Restricted Substances List) and other chemical safety requirements.
Lead post-season analysis of yarn performance based on customer feedback and return data, driving continuous improvement in material selection.
Mentor and educate junior team members and cross-functional partners on the fundamentals of yarn science, construction, and its impact on the final product.
Manage counter-sourcing and development projects to validate secondary or tertiary suppliers for key yarn programs, ensuring supply chain security and flexibility.
Evaluate the impact of different dye and finish applications on yarn hand-feel, performance, and color consistency, guiding suppliers to achieve desired outcomes.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis on yarn costs, usage, and performance.
Contribute to the organization's broader materials strategy and sustainability roadmap.
Collaborate with business units to translate data-driven insights on material performance into engineering and development requirements.
Participate in sprint planning and agile ceremonies within the product development and design teams.
Assist in preparing materials for key product milestone meetings, providing expert input on all yarn-related topics.
Support marketing by providing detailed technical stories and benefits behind key material innovations.
