About the Role

Argentina lives and breathes streaming and gaming, yet most brands have barely scratched the surface of these platforms’ advertising power. Millions of active, highly engaged users are waiting, and substantial media budgets are ripe for the taking.

We are looking for a Senior Client Partner to lead this charge, sit across from the country’s top media directors, C-level executives, and media agencies, and take full ownership of this market.

Your mission is not to maintain accounts; it is to win market share.

What You Will Do

• Capture ad spend: Turn traditional and digital media budgets (inversión publicitaria) into high-impact advertising campaigns across both the Twitch and Roblox ecosystems.
• Play in the big leagues: Serve as the strategic face and primary commercial authority for two global platforms across Argentina’s leading media agencies and top advertisers.
• High-level consultative selling: Translate digital ad metrics (VTR, CPV, viewability, engagement) into ironclad media plans that deliver real ROI for FMCG, tech, retail, and entertainment brands.
• Scale and sales focus: Leverage cutting-edge automation and AI tools to eliminate operational busywork, keeping 100% of your energy focused on prospecting, negotiating, and closing deals.

What We Are Looking For

• You are a proven closer: You bring 5+ years of digital advertising sales (ad sales / media buying) experience within media agencies, AdTech, or digital platforms, backed by direct relationships with key decision-makers across Argentina.
• You know the product inside out: You understand how high-engagement digital media is bought and sold, and you can convincingly make the case for why brands must invest in gaming and live streaming over legacy channels.
• You have a pioneering mindset: You are not looking for the comfort of a passive portfolio; you thrive on unlocking market share from scratch, closing large-scale deals, and maximizing revenue.
• Bilingual fluency: Full professional proficiency in both Spanish and English to seamlessly navigate local relationships and global internal stakeholders.

Why Join Aleph

• Impact: Be the strategic face of two global platforms, Twitch and Roblox, and take ownership of a market where your work directly shapes results.
• Growth: Build market share from scratch with the backing of a global organization. Aleph gives its internal talent room to learn, take on bigger scope, and grow together.
• Team culture: Join a place of many cultures, perspectives, and talents, where people support each other and communication and partnership come first.
• Market context: Argentina is a streaming and gaming market with millions of highly engaged users and media budgets still largely untapped by brands.
• Flexibility: A hybrid setup (2 days per week in the Buenos Aires office) that balances collaboration and focus time.
