Campaign Analyst - US

Job Summary We are excited to announce an incredible opportunity to join Smadex’s growing US team. We seek a quantitative, proactive analyst who can translate complex data into decisive trading strategies, driving extraordinary performance results for our US client base. This is a critical revenue-generating role, acting as the primary execution and optimization engine for Smadex’s high-budget performance campaigns. This individual is a quantitative professional responsible for expert execution in our proprietary platform, owning the strategic trading decisions that maximize client ROAS and LTV. This role demands analytical self-sufficiency and exceptional strategic communication to articulate performance drivers to internal teams. Important note: This role is fundamentally focused on performance strategy and optimization application. Candidates must understand data systems but are explicitly not required to possess skills in: Developing ETL pipelines; writing production-level code or scripts (e.g., Python, R, Java) for modeling or automation; architecting core BI reporting infrastructure (e.g., SQL development for internal tools, dashboard creation); or engineering/fine-tuning core machine learning models. We hire dedicated Data Engineers, BI Analysts, and Data Scientists to handle tool and infrastructure development, allowing our Campaign Analysts to focus 100% on driving client revenue. Key Responsibilities Own the setup, monitoring, troubleshooting and real-time optimization of mobile performance campaigns (UA and Re-engagement) across the Smadex platform. Independently extract, aggregate, and analyze complex delivery and performance data to proactively identify anomalies, diagnose trends, and synthesize clear, actionable strategic recommendations for account growth. Use a hypothesis-driven approach to identify scaling opportunities and mitigate risks, making timely, data-informed decisions utilizing educated assumptions to reach core customer business goals (e.g., retention, specific CPA/ROAS targets, LTV maximization) and seize growth opportunities. Serve as the internal technical authority on campaign delivery, ensuring accurate configurations, reliable campaign delivery, and strict adherence to internal policies. Conduct initial triage and first-level troubleshooting for all operational issues, including tracking discrepancies or supply connection issues working with Engineering and Data Science if needed on platform-level or core infrastructure escalations. Articulate complex optimization strategies and the value generated by the proprietary Smadex technology to internal teams in clear, commercially compelling language. This requires the ability to explain the technical "why" behind the performance results. Collaborate closely with Customer Success and Sales teams to ensure trading strategies are seamlessly aligned with client expectations and contract fulfillment. Synthesize critical performance observations and operational bottlenecks into structured feedback for the Product and Engineering teams, actively contributing to the enhancement of the platform roadmap.
