πŸš€ Role Summary

  • This role is specifically focused on enhancing the Direct-to-Consumer (DTC) e-commerce storefront, concentrating on UI design with a strong UX foundation to drive conversions and improve customer engagement.

  • The designer will be instrumental in creating visually appealing and intuitive user interfaces for product pages, campaign creatives, and website redesigns, directly impacting the customer journey and business outcomes.

  • A key aspect of this position involves transforming briefs and rough concepts into high-quality digital designs that balance aesthetic appeal with functional effectiveness and conversion optimization.

  • The role requires a candidate with proven experience in B2C/e-commerce or DTC design, particularly within the health, wellness, or supplements sector, to ensure designs resonate with the target audience and business objectives.

πŸ“ Enhancement Note: While the job title is UX/UI Designer, the description heavily emphasizes UI craft and conversion-focused design for an e-commerce platform. The "UX experience" mentioned suggests a need for understanding user flows and conversion principles rather than deep, end-to-end UX research. The role is embedded within the e-commerce team, indicating a direct impact on sales and customer acquisition strategies.

πŸ“ˆ Primary Responsibilities

  • Design and iteratively improve product pages, focusing on visual appeal, clarity of information, effective Call-to-Actions (CTAs), and trust elements to maximize conversion rates.

  • Develop engaging and persuasive campaign creatives that clearly communicate brand messaging and drive user action, aligning with marketing objectives.

  • Execute website redesigns and improvements by identifying opportunities to enhance user experience, increase engagement metrics, and boost overall conversion rates.

  • Translate project briefs, abstract ideas, and campaign concepts into polished, high-fidelity designs that adhere to brand guidelines and business goals.

  • Apply UX principles to strategically place key information, CTAs, trust signals, and benefit highlights to guide user decision-making and facilitate seamless navigation.

  • Proactively consider the end-to-end user journey during the design process, ensuring a natural, friction-free flow from initial interaction to purchase.

  • Maintain and evolve visual design consistency across the website, campaign assets, and various digital touchpoints to reinforce brand identity.

  • Demonstrate agility in adapting and refining designs based on performance data, A/B testing results, stakeholder feedback, and evolving business priorities.

  • Ensure all designs are fully responsive and optimized for optimal viewing and interaction across both desktop and mobile devices.

πŸ“ Enhancement Note: The responsibilities clearly indicate a focus on conversion rate optimization (CRO) and e-commerce performance. Responsibilities like "improving the user experience, engagement, and conversion" and "how design can influence user behavior and decision-making" highlight the business-critical nature of this role.

πŸŽ“ Skills & Qualifications

Education: While no specific degree is mandated, a background in Graphic Design, Digital Design, Human-Computer Interaction, or a related field is beneficial. Emphasis will be placed on a strong portfolio showcasing relevant design work.

Experience: Minimum of 2 years of dedicated UX/UI design experience, with a mandatory focus on e-commerce or Direct-to-Consumer (DTC) brands. Experience in the health, wellness, or supplements industry is highly advantageous.

πŸ“ Enhancement Note: The requirement for "minimum 2+ years designing for e-commerce or DTC brands" is stated as a "must-have," indicating that candidates without this specific experience will likely not be considered.
