About the Company

A venture-backed (a16z) early-stage startup is building the monetization infrastructure for the next generation of consumer AI platforms. The company is rethinking traditional advertising by replacing static formats with AI-native, interactive experiences embedded directly into AI products—such as rewarded video, dynamic branded content, and gamified ads.

With rapid growth in the AI companion space (now reaching tens of millions of daily users), the company sits at the center of this shift, enabling partners to effectively monetize their audiences. The team is small, highly technical, and execution-driven, with direct founder involvement in product development.

About the Role

This is a critical, high-ownership position responsible for leading the development of the company’s mobile Ad SDK end-to-end. You will take over a core system currently owned by the founder and drive it through architecture, compliance, certification, and production at scale.

The role requires strong execution speed, attention to detail, and prior experience with mobile SDKs—particularly within the AdTech ecosystem.

Key Responsibilities

• Design and build native iOS (Swift) and Android (Kotlin) SDKs supporting multiple ad formats (native, rewarded video, interstitial)
• Integrate and manage the IAB Open Measurement SDK (OMID) lifecycle through certification
• Collaborate with verification vendors (e.g., MOAT, IAS, DoubleVerify) to ensure measurement accuracy
• Implement privacy and consent frameworks (TCF v2.2, GPP, ATT, COPPA)
• Monitor live production traffic to ensure signal integrity and performance
• Manage SDK distribution (CocoaPods/SPM, Maven Central) and maintain clear integration documentation
• Deliver on aggressive milestones, including OMID certification and third-party validation

Requirements

Must-Have

• 3+ years of experience building mobile SDKs or libraries (not just applications)
• Strong expertise in Swift (iOS) and Kotlin (Android)
• Prior experience working with AdTech or ad SDKs
• Hands-on experience with OMID integration and ad measurement standards
• Solid understanding of the mobile ad lifecycle (request → render → impression → conversion)
• Experience with verification tools and vendors

Nice to Have

• Experience leading OMID certification processes
• Background in ad networks, DSPs, SSPs, or mediation platforms
• Familiarity with VAST video standards and mobile video players
• Experience handling edge cases in ad measurement (visibility, backgrounding, WebViews)
• Exposure to cross-platform SDKs (React Native, Flutter, Unity)
• Experience supporting high-scale SDKs (1M+ DAU)

Environment & Benefits

• Fully remote (LATAM)
• Direct collaboration with the founder and core team
• Fast-paced, high-ownership culture with minimal bureaucracy
• Performance-driven upside as the company scales
