Your primary focus will be on cultivating and expanding business opportunities within the Korean market, a region identified as a critical growth area for our organization. This involves a dual approach: engaging directly with major advertisers and nurturing robust partnerships with leading advertising agencies.
  • • You will be responsible for developing and executing a comprehensive sales strategy tailored to the unique dynamics of the South Korean digital advertising landscape. This includes identifying new business prospects, understanding client needs, and crafting compelling solutions that leverage the full potential of X's advertising capabilities. Your expertise will be crucial in helping both local and global businesses achieve their advertising objectives.
  • • A key aspect of your role will involve building and maintaining strong, long-lasting relationships with key stakeholders across the advertising ecosystem. This includes direct engagement with brand marketers, media planners, and decision-makers within client organizations. Furthermore, you will be expected to develop and deepen relationships with senior leaders at major advertising agencies, understanding their strategic priorities and demonstrating how X can help them deliver exceptional results for their clients.
  • • You will play a pivotal role in supporting agency trading agreements, ensuring that X is positioned as a preferred partner. This requires a deep understanding of agency business models, trading practices, and the ability to negotiate mutually beneficial terms. Your commercial acumen and negotiation skills will be essential in securing and optimizing these critical partnerships.
  • • Success in this role hinges on your ability to not only meet but exceed ambitious revenue targets. You will be expected to manage a sales pipeline effectively, forecast accurately, and consistently deliver strong commercial outcomes. This involves a proactive approach to identifying market trends, competitive landscapes, and emerging opportunities within the digital advertising space.
  • • Beyond direct sales, you will act as a trusted advisor to your clients and agency partners, providing insights and strategic guidance on how to best utilize X's advertising solutions. This includes staying abreast of platform updates, new product launches, and best practices in digital advertising to ensure your clients are always at the forefront of innovation.
  • • You will collaborate closely with internal teams, including marketing, product, and operations, to ensure a seamless client experience and to provide valuable market feedback that informs product development and strategic planning. Your ability to work cross-functionally will be key to driving integrated campaigns and maximizing client success.
  • • This role offers a unique opportunity to shape the future of digital advertising in a dynamic market. You will have the autonomy to develop and implement innovative sales strategies, build a strong presence for X in Korea, and contribute directly to the company's global growth trajectory. If you are a high-achiever with a strategic mindset and a passion for the digital advertising world, we encourage you to apply.
  • • Ultimately, you will be the face of X in the Korean market, responsible for driving its commercial success and solidifying its position as a leading advertising platform. This is a challenging yet incredibly rewarding opportunity for a sales leader looking to make a significant impact.
