Smadex is a leading advertising technology company founded in Barcelona in 2010 and sold to American-based and stock-listed Entravision in 2018 (NYSE::EVC). We power campaigns for Apps, Games and Brands across Mobile and CTV using advanced machine learning and optimized creative strategies to deliver results. Smadex is one of the fastest growing DSPs globally and we are adding talent to fuel our ambitious plans.

We are excited to announce an incredible opportunity to join Smadex’s growing US team. We seek 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.

Required skills and qualifications:

• Minimum of 2 years of hands-on experience in programmatic media buying, mobile user acquisition, or performance trading within the AdTech ecosystem.
• Proven record of driving measurable growth and optimizing campaigns based on client-specific KPIs (e.g., CPA, ROAS, LTV).
• Exceptional data analysis skills, including expert proficiency with advanced data manipulation and reporting in tools such as Excel.
• Demonstrated ability to perform logical, hypothesis-driven problem-solving, making quick, sound decisions under pressure.
• Superior verbal and written communication skills suitable for communicating strategic concepts to commercial and executive stakeholders.
• Strong functional knowledge of key programmatic and mobile advertising concepts will be extremely valued.

What’s in it for you?

• Be part of a leading, fast-growing, innovative company shaping the future of mobile advertising.
• Join a highly motivated and young team.
• Possibility of traveling to the Barcelona HQ for collaboration and team-building activities after your first year.
