Descripción de la vacante

Jampp in Barcelona, Spain is looking for a Product BI Analyst to bridge data science and business decisions. This on-site, full-time role partners with Data Science and ML teams to analyze high-cardinality data and translate model changes into business impact on CPI, CPA and ROAS.

You will monitor A/B tests, build dashboards (Looker/Tableau), and deliver proactive insights to improve advertiser performance. Fluency in English and Spanish is preferred.

Formación

• 4-8 years of experience in Data Analytics, BI, Marketing Analytics, or Growth Analytics.
• Strong SQL and working proficiency in Python (pandas-level analysis).
• Experience with BI tools — Looker and/or Tableau.
• Experience with cloud data warehouses (BigQuery preferred; Snowflake/AWS valuable).
• Solid grasp of A/B testing and experimentation fundamentals.
• Understanding of how a DSP/ad-tech ecosystem works — auctions, impressions, SSPs, MMPs.
• Background in a DSP, SSP, ad exchange, or mediation platform is welcome.
• Comfortable working with high-volume, high-cardinality data.
• Good communication skills in both English & Spanish.

Responsabilidades

• Monitor ongoing A/B tests across models and campaigns, going beyond 'did it win or lose' into why, and for which advertisers or segments.
• Deep-dive into auction-level and campaign data — large volumes, high cardinality (millions of apps, placements, creatives) — to surface patterns the team hasn't already been looking for.
• Build and maintain dashboards and reporting frameworks (Looker/Tableau) that give the team clear, actionable visibility into performance.
• Translate technical model changes into business impact: what it means for CPI, CPA, and ROAS, and where there's an opportunity to push for more advertiser budget.
• Bring proactive ideas to the table. We're not looking for passive reporting — we want insight, brainstorming, and pushback.
• Work with automated pipelines (SQL, Python) to keep monitoring and reporting scalable as the team and initiative grow.
• Partner closely with Data Scientists and ML Engineers: understand what's being built, flag data quality issues, and validate results from a business lens.
