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.

• 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.

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.
