Senior Software Engineer II, Mobile - On App Ads (AI Native)

Role overview

Lead development of the iOS advertising experience in a high-traffic mobile app, owning core SDK capabilities, advertising partner integrations, and privacy controls. The work balances revenue and ad performance with fast, reliable app behavior and respect for members’ choices. You’ll use AI-assisted development as a regular part of engineering and may contribute across platform boundaries when integrations or experiments require it.

Responsibilities

- Build and maintain the iOS advertising SDK, mediation, and demand integrations, including header bidding. - Develop new ad formats and placements while protecting app startup time, scrolling performance, and user experience. - Implement consent and privacy behavior across regions, including attribution and tracking preferences. - Monitor ad quality and diagnose rendering, fill, and latency issues with operations and engineering partners. - Instrument ad events and run configuration experiments; use reliable results to guide product decisions. - Use AI coding tools to support specification, implementation, testing, and review, while taking responsibility for shipped work.

Requirements

- Strong professional iOS engineering experience, particularly with Swift and mobile application development. - Experience owning software through design, implementation, release, and production support. - Ability to investigate complex technical issues and explain tradeoffs clearly to engineering and cross-functional partners. - Practical experience using AI coding assistants for substantial development tasks, with careful review of generated work. - Collaborative approach and willingness to learn or contribute beyond iOS when the work calls for it.

Nice to have

- Experience with mobile advertising standards, SDKs, mediation, or header-bidding integrations. - Familiarity with mobile consent, privacy, and attribution frameworks, or building SDKs used by other teams. - Experience with ad quality diagnostics, experimentation platforms, iOS delivery pipelines, or Android/Kotlin. - Familiarity with agent-based workflows, prompt design, context management, or tool integrations.

Benefits and work setup

- Remote-first work within the United States or Canada. - Benefits include health coverage, retirement savings programs, paid parental leave, flexible time off, learning support, and equipment for remote work.
