Your primary responsibility will be identifying and acquiring direct advertisers, casino operators, and iGaming products, negotiating competitive commercial terms, and developing a profitable portfolio of offers.

We need a commercially driven professional with strong B2B sales skills who can independently manage the full business development cycle, from initial outreach and negotiations to integration, traffic launch, and account growth.

Priority GEOs: LatAm, Asia, MENA, Africa.

Responsibilities

• Identify and acquire direct advertisers, casino operators, and iGaming products for the CPA network.
• Establish relationships with decision-makers and manage the entire B2B sales cycle.
• Build and expand a portfolio of direct advertisers and competitive iGaming offers.
• Negotiate CPA, RevShare, and Hybrid agreements, including rates, caps, conversion qualification criteria, holds, and payment terms.
• Identify the affiliate team's demand for specific GEOs, traffic sources, and products.
• Coordinate advertiser onboarding, technical integrations, postback/API setup, and tracking verification.
• Work closely with Affiliate Managers to organize initial traffic tests and evaluate results.
• Develop existing advertiser relationships, negotiate higher caps and improved rates, and introduce additional GEOs and products.
• Monitor offer performance, conversion approval rates, traffic quality, and portfolio profitability.
• Participate in reconciliation processes, resolve payment discrepancies, and coordinate outstanding payments with the finance team.
• Maintain accurate CRM records, commercial forecasts, and launch pipelines.
• Represent the network at industry conferences and business events.

Requirements

• 2+ years of relevant Business Development, B2B Sales, or Advertiser Management experience in iGaming for Middle-level candidates; 3+ years for Senior-level candidates.
• Mandatory hands-on experience working on the CPA network or media buying side, personally sourcing and onboarding direct advertisers, casino operators, or iGaming products.

• Understanding of affiliate traffic, media buying, SEO, and advertisers' requirements for different traffic sources.
• Familiarity with affiliate tracking, postback/API integrations, and technical launch coordination.
• Analytical mindset and experience working with CRM systems, commercial KPIs, and performance reports.

• English proficiency sufficient for independent international business negotiations, preferably B2 or higher.

What Matters Most

We are specifically looking for someone who has personally acquired and onboarded direct advertisers or iGaming products into a CPA network or media buying operation.

The ideal candidate should be able to independently source advertisers, negotiate profitable deals, coordinate launches, and demonstrate measurable commercial results.
