Your ultimate goal is not just to build brand image, but to deliver measurable business impact - acquiring new customers, driving DTC revenue, and improving unit economics. You must deeply understand the clear criteria for what makes a winning creative, recognizing that these benchmarks constantly evolve alongside the algorithms of Meta, TikTok, and YouTube.  * This is not a pure execution role; it requires a relentless growth mindset that drills down into the "why" behind performance data and immediately creates the "how" to execute the next iteration. You will use advanced data platforms to understand exactly why an ad wins or loses, applying those insights to lead cross-functional teams in producing high-converting, trust-building content tailored specifically for the US consumer that directly impacts the bottom line. At the core of this content is compelling storytelling; you will act as the voice of the brand, translating our values into authentic narratives that build deep trust and long-term relationships with our customers. Job Description A) Creative Intelligence & Analytics (Core Focus) * Find the Winning Formula: Utilize hands-on creative analysis experience to drill into performance data. Track metrics like Hook Rate, Hold Rate, View Rate, and CVR to continuously define and refine what makes a winning asset based on current platform algorithms. * Develop Growth Strategies: Develop playbooks, content testing frameworks, new formats, and test strategies to unlock fresh growth. * Brand Storytelling & Trust Building: Master the art of communicating the brand story through performance creatives. Design narratives that authentically connect with customers, building the crucial trust needed to bridge the gap between initial engagement and final conversion. * Connect Creative to Business Impact: Partner closely with Business Analysts to bridge the gap between top-of-funnel ad metrics and bottom-line business results. Ensure every creative testing plan is grounded in driving tangible business outcomes (e.g., lower CAC, higher LTV, higher AOV, revenue growth) rather than purely focusing on brand awareness or aesthetics. * Initiate Creative Testing Plans: Build and drive rigorous, structured testing frameworks. Systematically isolate and test different creative variables, including the hook, body, and CTA, as well as distinct scripts, messaging angles, visual styles, settings, product benefits, and consumer motivations. * Market Research & Swipe File Management: Continuously monitor competitor intelligence and industry trends. Curate creative inspiration and maintain an active swipe file to fuel the next wave of data-driven testing. B) Production & Workflow Management * Drive High-Volume Output: Manage a high-velocity production schedule to consistently produce 15–25 high-quality ad variants per week, depending on the scale and complexity of the creatives. Track the status of all assets from ideation to delivery. * Cross-Team Management: Act as the operational bridge for production. Collaborate seamlessly with in-house designers, video editors, and external agencies to ensure all creative deliverables are produced on brief, on schedule, and delivered on time. * Translate Strategy to Execution: Take creative testing plans and translate them into clear, actionable, production-ready tasks for the execution teams. * Asset Organization: Maintain a pristine, highly organized asset library. Categorize raw footage, winning creatives, and print assets so they are easily accessible to the broader team. C) Quality Control & US Market Localization * Rigorous Ad QC: Review every single ad before final delivery. Ensure the visual hook, ad copy, CTA, and landing URLs are flawless, scalable, and aligned with the brand guidelines. * US Cultural Nuance: Evaluate every piece of content through the lens of the US consumer. Ensure the storytelling, pacing, and hooks are designed to stop an American consumer from scrolling.   Requirement * 6+ years in Western DTC/e-commerce ad creative production, including 2+ years of data-driven creative analysis. * Track record managing high-volume production with internal teams and external agencies under tight deadlines. * Expertise in performance-driven Meta, TikTok, and YouTube ads across static and video formats. * Deep understanding of US consumer nuances for effective QC of copy, slang, and visual hooks. * Hands-on experience using data (e.g., Meta Ads Library, Motion) to drive production decisions; additional attribution tools preferred. * Mandatory skills in CapCut and Canva; proficiency in AI tools and Adobe Suite preferred. * Highly organized with proficiency in project management systems like Monday.com or Notion. * Trilingual fluency in English, Cantonese, and Mandarin for cross-functional collaboration. * Proactive team player capable of delivering high-quality work in fast-paced environments. * Proven ability to partner with analysts and leadership to drive marketing goals.
