[Company Overview]

Our mission is to revolutionize the way organizations make decisions by leveraging the power of AI and data. We provide comprehensive solutions across three key dimensions—management, business operations, and organizational development.

We are not just an analytics firm, an advertising agency, or a SaaS vendor. We are a data-driven company that partners with purpose-driven clients, working alongside them until tangible results are achieved.

[Job Description]

In this role, you will be responsible for strategic planning, campaign management, and performance analysis, focusing primarily on Amazon Advertising.

Based on each e-commerce client's KPIs, you will manage advertising operations end-to-end—from campaign design and execution to optimization and improvement proposals—to maximize advertising effectiveness.

You will also conduct business reviews, share industry insights, and, for certain projects, collaborate with the analytics team using Amazon Marketing Cloud (AMC) to deliver data-driven improvement strategies.

[Key Responsibilities]

• Participate in regular meetings with e-commerce clients to report performance results, identify challenges, and propose actionable solutions
• Design and propose advertising strategies aligned with clients' KPIs and business goals
• Execute and manage advertising campaigns—primarily Amazon Ads (including Amazon DSP)
• Depending on the company's situation, you may also manage advertising campaigns on other platforms
• Optimize campaigns using Quartile, including bid adjustments, keyword management, and campaign structure optimization
• Monitor and improve key performance metrics such as ACoS, ROAS, CTR, and CVR
• Collaborate with data analysts and the data team to propose data-driven advertising initiatives (e.g., promotional strategies for new listings, ad optimization during sales periods)
• Position Highlights & Career Growth
• With the rapid expansion of the e-commerce market, the demand for Amazon Advertising is growing quickly—offering an excellent opportunity to sharpen your skills in a high-growth field
• You can go beyond a single product or platform, leveraging AMC and external tools to discover the optimal, data-driven advertising solutions
• Gain hands-on experience using Quartile, one of the most advanced AI-based Amazon Ads optimization tools
• Opportunity to work with a wide range of ad tech solutions such as Quartile and ZEFR, allowing you to expand your technical expertise and strengthen your professional toolkit as a campaign manager

[Required skills]

• Native or fluent level of Japanese
• Hands-on experience managing Amazon Advertising campaigns (strong understanding of Sponsored Ads formats)
• Experience in client-facing roles, including developing and executing advertising strategies based on client needs
• Strong numerical and analytical skills using Excel or Google Sheets
• Excellent logical thinking, problem-solving, and proposal skills
• Ability to work backward from business goals to develop hypotheses and actionable strategies

[Preferred Skills]

• Experience managing DSP or social media advertising campaigns (e.g., Google, Yahoo, Criteo, The Trade Desk, TikTok, etc.)
• Basic business communication skills in English (for collaboration with global headquarters)
• Familiarity with e-commerce platforms such as Amazon Seller Central or Vendor Central
• Experience in digital advertising campaign planning and operations
• Experience in customer success for SaaS products
