Under Armour Product Designer Letter of Interest

Subject: Letter of Interest for Product Designer Opportunities at Under Armour
Dear Under Armour Recruiting Team,
I am writing to express my enthusiastic interest in Product Designer opportunities at Under Armour. Throughout my professional
design career in performance sportswear, technical apparel, and athletic footwear, I have continually revered Under Armour as
an unstoppable force in human-centered innovation and athlete-driven product design. From pioneering moisture-wicking
synthetic baselayers to delivering groundbreaking cushioning and upper construction technologies, Under Armour has
consistently set the standard for high-performance equipment that empowers athletes to surpass their limits. I am eager to
contribute my background in industrial design, rapid prototyping, biomechanical user research, material development, and 3D
CAD modeling to support Under Armour in crafting next-generation performance products.
Currently serving as Senior Performance Product Designer at Apex Sportswear Innovation Lab, I lead end-to-end design
initiatives across technical apparel and footwear lines tailored for elite training and outdoor performance. My academic
foundation includes a Bachelor of Fine Arts in Industrial Design from the Rhode Island School of Design, complemented by
specialized coursework in textile science and human factors engineering. Over the past six years, my design practice has
focused on translating qualitative athlete insights into athletic equipment through concept sketching, digital surface modeling in
Rhino and SolidWorks, photorealistic rendering in KeyShot, and pattern development using Adobe Creative Suite and PLM
systems.
Throughout my career, I have focused on unifying aesthetic expression with functional performance and sustainable
construction. Recently, I spearheaded the design and development of an ultra-lightweight, thermo-regulated training apparel
collection utilizing bio-based, recycled synthetic yarns. By conducting biomechanical strain-mapping studies and iterating high-
fidelity functional prototypes, my team optimized seam construction and strategic ventilation zones, reducing total garment
weight by 18% while enhancing breathability and tear strength under high-abrasion conditions. This collection achieved a 25%
increase in consumer satisfaction ratings and earned an industry award for sustainable performance innovation.
Bringing innovative consumer products from initial sketch to commercialization requires active cross-functional leadership and
collaborative alignment across global teams. In my daily workflow, I work closely alongside product managers, biomechanics
researchers, materials developers, garment technicians, sourcing leads, factory engineering teams, and athlete advisory panels.
I prioritize a rigorous design thinking methodology, utilizing trend analysis and hands-on wear-tester feedback to refine
ergonomics, fit, and color stories. My familiarity with commercial manufacturing processes and material validation testing
ensures that creative design concepts translate seamlessly into mass production without compromising structural integrity or
visual impact.
What draws me most compellingly to Under Armour is its grit, athletic passion, and relentless commitment to solving problems
for athletes. Under Armour’s dedication to athlete-first design, advanced material research, and sustainable manufacturing
reflects a brand identity that genuinely inspires peak human performance. Joining Under Armour would allow me to collaborate
with world-class designers and developers, leverage state-of-the-art innovation facilities, and directly contribute to crafting
iconic, high-performance equipment that helps athletes everywhere achieve greatness.
Thank you for your time, consideration, and continued leadership in athletic performance and product design. I welcome the
opportunity to discuss how my industrial design experience, material innovation background, and passion for sportswear align
with Under Armour’s product strategy and creative design objectives.
Sincerely,
Julian Mercer
