Position Summary

The Supplier Quality Engineer (SQE) for Socks & Technical Knitwear is the ultimate gatekeeper of material integrity, structural quality, and manufacturing standards across our integral supply chain. This is a highly technical, hands‑on role.

1. Technical Material & Yarn Quality Assurance

- Yarn & Fiber Validation: Audit and verify raw materials, ensuring that yarn counts, filament structures, and fiber compositions (Nylon, Spandex, Combed Cotton blends) meet structural compression and performance benchmarks.
- Grip & Polymer Chemistry Integrity: Oversee the quality, execution, and durability of silicone/PVC grip applications on performance socks. Troubleshoot and resolve adhesion failures, cracking, or peeling caused by fabric softeners or chemical finishes.
- Lab Testing Compliance: Manage physical and chemical laboratory testing protocols (e.g., colorfastness to sweat/washing, abrasion resistance, pilling benchmarks, and ASTM stretch & recovery metrics). Interpret third‑party lab results to approve or reject bulk material lots.

2. Factory Quality Management & Production Auditing

- Knitting Machinery & Specification Alignment: Preview and technically audit sample stages (Protos, SMS, PPS) against Tech Packs. Verify machine cylinder diameters, stitch tension, and needle counts/gauges to ensure production capability.
- Root‑Cause Analysis (RCA): Lead the technical investigation and resolution of manufacturing and structural defects (e.g., irregular shrinkage, yarn breakage, seam failures, or sizing distortions).
- Supplier Risk & WIP Monitoring: Conduct quality risk assessments on high‑complexity styles. Routinely monitor factory WIP (Work‑In‑Progress) logs and audit factory quality management systems (QMS) to ensure consistent output.

3.



International Communication & Cross‑Functional Alignment

- Global Supplier Accountability: Direct daily technical communication with overseas finished‑goods manufacturers and yarn mills (primarily in Asia). Hold vendors accountable to strict quality corrective action plans (CAPA). Note: Requires flexibility for bi‑weekly after‑hours calls due to overseas time zones.
- Cross‑Functional Feedback: Partner closely with Product Development and Design teams to review wear‑testing trials and feedback, ensuring that quality standards are engineered into the product without sacrificing design intent.

Job Requirements & Qualifications

- Education: Bachelor’s degree in Textile Engineering, Material Science, Industrial Manufacturing Engineering, or a highly technical, knitting‑focused discipline.
- Experience: 5+ years of experience as a Supplier Quality Engineer (SQE), Quality Assurance Engineer, or Technical Developer within the apparel industry. Explicit experience in socks, hosiery, or seamless knitwear production is mandatory.

- Technical Skills:
- Deep applied comprehension of sock circular knitting machinery, needle counts, and cylinder gauges.
- Profound knowledge of technical yarn performance properties (moisture‑wicking, antimicrobial, high‑elongation Spandex).
- Expertise in executing Corrective and Preventive Actions (CAPA) and root‑cause analysis methodologies (5 Whys, 8D, Fishbone).
- Advanced proficiency in MS Excel (Master Data/WIP tracking) and basic familiarity with Adobe Illustrator and PLM systems.

- Language & Travel:
- 100% Fluent English is mandatory (C1/C2 level) for daily international vendor management and corporate reporting.
- Must possess a Valid U.S. Visa and the ability to travel internationally to audit material mills and production lines on‑site.
