• Build and evolve the engineering systems that power paid growth at scale: creative experiment frameworks, audience/signal ingestion and privacy-safe list management, budget and bid optimization tooling, and reliable attribution and reporting pipelines
• Collaborate with data science and ML partners to design experiments, apply personalization/targeting, and translate insights into product improvements and bookings growth
• Own planning and execution for projects that directly impact revenue; identify the right team‑level metrics to optimize and protect delivery through clear milestones and risk management
• Bring both technical and product perspectives to new ideas, enabling rapid hypothesis testing without sacrificing reliability, observability, or long‑term maintainability
• Set and uphold engineering quality standards and practices that improve reliability, scalability, and operability across Ads systems

Requirements:

• 2+ years of experience leading, managing, and building a team of software engineers
• A track record of owning multi‑engineer, multi‑week technical projects to successful outcomes in a highly experimental, data‑driven environment
• Strong product instincts and excellent written/verbal communication, with experience aligning diverse stakeholders across engineering, product, design, and analytics
• Experience working closely with data, experimentation, or machine learning teams to inform prioritization and ship measurable impact (direct ML expertise not required)
• Demonstrated ability to raise the bar on engineering practices for reliability, scalability, and observability
• Prior experience with advertising platforms, ad tech integrations, or building ad surfaces in mobile apps
• Experience improving ad quality and monetization through experimentation, targeting, or programmatic levers, in partnership with business teams
• Familiarity with COPPA‑compliant or kid‑friendly ad solutions and the trade‑offs of untargeted inventory
• Background collaborating with sales/biz ops on direct or programmatic campaigns and translating market feedback into product improvements
• Experience leading teams that span multiple platforms (iOS, Android, backend) and partnering on ML‑powered personalization within consumer apps
