About Us

Tirarin Co., Ltd. is a specialized Fashion Agency that takes fashion from concept to reality — design, manufacturing oversight, QC, and logistics. We partner closely with brand clients to bring their creative visions to life, working with factories and mills in China to deliver exceptional products. We're growing, and we're looking for a talented Fashion Developer to join the team!

Position Overview

We're looking for an experienced Fashion Developer to be the bridge between our brand clients' creative visions and the real-world possibilities of materials and manufacturing. You'll translate concepts into production-ready garments — developing fabrics, refining silhouettes, and crafting precise tech packs — while serving as a trusted commercial design consultant from concept all the way to delivery.

What you'll do

• Research and develop fabrics and trims with mills in China, including custom yarns, finishing, wash, print, and dye — and recommend the right materials to clients with confidence
• Translate client briefs, mood boards, and trend directions into compelling development proposals covering silhouette, construction, and fabric options
• Create detailed flat drawings (front / back / detail views) and comprehensive tech packs covering construction, BOM, measurement specs, and finishing — clear enough for any factory team to execute
• Manage the full development calendar: Concept → Proto → Fit → SMS → PP → TOP
• Collaborate closely with factory R&D, sampling, and sourcing teams in China — including travel to factories and mills 1–2 times per year
• Present fabric stories, collection directions, and development proposals to clients — and offer honest commercial advice when designs need adapting for cost or production feasibility
• Manage costing: request and compare quotations, analyze cost structures (fabric, trim, CMT, freight, margin), and negotiate toward target costs
• Keep all sample rounds on schedule, maintain version control across every revision, and escalate issues proactively

What we're looking for

• 3–5+ years of experience in product or fashion development within the garment industry
• Background in an OEM, agency, sourcing office, or brand-side environment — with direct hands-on experience working with factories and mills in China
• Proficient in Adobe Illustrator and Photoshop for flat drawings, color boards, and fabric boards
• Deep knowledge of fabric construction, yarn, finishing, dyeing, printing, and washing techniques
• Strong understanding of garment construction and manufacturing processes — enough to hold detailed technical conversations with factory teams
• A well-developed sense for trend, color, silhouette, and commercial viability — all at once
• Excellent written and spoken English (weekly online meetings with international brand clients)
• Mandarin Chinese proficiency is a significant advantage and will be considered preferentially
• Bachelor's degree in Fashion Design, Textile, Apparel Technology, or a related field
• Comfortable managing multiple development programs and clients simultaneously
