Mobile SDK Developer, Kargo

• 5+ years of software engineering with significant exposure to mobile app advertising technologies
• Strong grasp of the mobile programmatic ecosystem — mediation, bidding, SDK integrations, OpenRTB, and ad rendering workflows
• Hands-on experience with mobile ad creative standards and cross-platform behavior across SDKs, WebViews, and mediation partners
• Proven ability to debug the full in-app stack, from creative delivery through rendering and attribution
• Performance engineering fundamentals: latency optimization, scalability, and system efficiency
• Fluency with real-device QA, inspection and proxy tooling, and production debugging techniques

Desirable

• This role exists to keep Kargo's in-app advertising reliable, performant, and revenue-ready across a fragmented ecosystem of devices, SDKs, mediation layers, and demand sources
• It owns deep technical investigation across the full ad lifecycle — from bid response through rendering and measurement — and helps elevate in-app advertising into a first-class part of Kargo's platform
• Without it, creative breaks silently across partners, integrations stall, and in-app revenue leaks through bugs no one can trace
• Outcomes — What Success Looks Like in 6–12 Months
• Faster issue resolution: Cut time-to-diagnosis for complex in-app failures spanning rendering, SDK behavior, mediation, and attribution, measurably reducing partner-facing escalations
• SDK reliability gains: Ship improvements to SDK and rendering infrastructure that improve render success rates and stability across iOS, Android, WebViews, and mediation partners
• Performance improvements: Deliver latency and efficiency optimizations across the ad stack with quantifiable gains in load time or resource use
• New integrations evaluated and landed: Partner with Business Development to assess and bring online [X] new vendor or demand integrations, with sound technical recommendations
• Raised engineering quality: Strengthen code review, testing standards, and AI-assisted workflows so production defects in the rendering path trend down quarter over quarter
• Systematic Debugging
• Isolates root cause across SDK, mediation, creative, and demand boundaries instead of patching symptoms
• Reasons through ambiguous, multi-party failures where the break could live in anyone's code
• Engineering Craft
• Builds for reliability and scale, treating rendering correctness and performance as features, not afterthoughts
• Raises the bar through code review, testing discipline, and thoughtful use of AI-assisted workflows
• Partner-Facing Judgment
• Communicates technical findings clearly to Business Development, partners, and non-engineers
• Weighs integration opportunities on technical merit and long-term maintainability, not just demand pressure
• Ownership Across Boundaries
• Drives production issues to resolution across engineering, product, and ops without dropping the thread
• Takes in-app advertising personally — treats its reliability and growth as their mandate
