Embark on an exciting career journey with Optima, recognized as one of the 1000 fastest-growing companies in Europe. We are currently seeking a highly skilled Data Analyt to join our vibrant team.
About Us: At Optima, we've had a front row seat to the fundamental changes of this industry we know and love. Whether it's a move from third-party data to first-party data, being ahead of the curve in programmatic, and preparing for a new cookieless world, we pride ourselves in removing the hassle. Our publishers can count on revenue streams that are optimized and predictable, so they can continue doing what they do best: inform and entertain general consumers.
Job Description As a Data Analyst, you'll own the numbers behind our publisher portfolio. You'll turn raw programmatic data into decisions: which publishers to onboard, where revenue is leaking, which levers move yield, and what our commercial teams should do next.
This is a high-ownership role with direct, measurable impact on revenue. You'll work daily with Business Development, Operations, and Demand, and you'll build deep expertise in the programmatic supply chain — SSPs, DSPs, header bidding, ads.Txt — from day one. If you want to become genuinely fluent in ad tech data,



there are few faster ways to do it.
Responsibilities: Analysis & insight Analyze prospective publishers: size the revenue opportunity, model expected yield, and pressure-test assumptions before we commit
Run deep-dive analyses on portfolio performance — yield by placement, format, geo, device, and demand partner — and translate findings into concrete recommendations
Build and maintain the metrics that define how we measure success, and defend their definitions when they're questioned
Identify patterns across publishers that others miss: seasonality, demand-partner behavior, bid-density shifts, traffic-quality signals
Performance monitoring & optimization Monitor daily performance across the portfolio (impressions, fill rate, CPM, CTR, viewability, revenue) against targets
Catch underperformance early, diagnose root causes with data rather than intuition, and make or recommend the adjustments that fix it
Troubleshoot delivery and discrepancy issues with internal teams and external partners, tracing numbers back through the stack to find where they diverge
