We’re looking for a Senior Business Data Analyst to join our team in Madrid and play a key role in shaping the future of neuro-contextual advertising at a global scale.
Seedtag is the leading Neuro-Contextual Advertising Company.
We are redefining how advertising works in a privacy-first world by moving beyond keywords and cookies, towards understanding human emotion, intent, and context.
Powered by advanced AI and neuroscience, our proprietary technology, Liz, delivers a deep, human-like understanding of content and attention. This enables brands to connect with audiences at the right moment, in the right mindset, with ads that are relevant, engaging, and respectful of the user experience.
Founded in 2014 by two ex-Googlers, Seedtag has grown into a global company with 650+ Seedtaggers across 17 countries, backed by €250M in funding, and expanding rapidly across the open web and Connected TV.
We’re not just building technology, we’re rewriting the rules of advertising.
As a Senior Business Data Analyst, you will get full ownership of our business data and will be expected to propose and conduct analyses that transform Seedtag’s data into significant business opportunities and KPI improvements.
Proactive Analysis: You will analyse the performance of our current Contextual products and processes, proactively proposing initiatives that seek to improve Seedtag’s commercial and operational results.
AI-Driven Automation: You will design, build, and deploy tools that automate internal processes, leveraging AI and Large Language Models (specifically Claude) to scale the efficiency and efficacy of Seedtag teams.
Data Democratization: You will help build tools and AI-assisted interfaces that enable the democratization of data inside the company, allowing Seedtag teams to gain instant visibility, surface business intelligence, and make informed, data-driven decisions.
Strategic Partnership & Industry Growth: You will collaborate closely with business stakeholders to solve complex use cases with data and AI, while building a solid knowledge of the adTech ecosystem and developing strong business acumen.
Background: You have a Bachelor's or Master's degree in Business, Economics, Mathematics, Computer Science, or Engineering. Specific certifications/education in Data, Business Intelligence, or Artificial Intelligence are a plus.
Experience: You have 3–5 years of experience in a fast-paced environment, either within a scale-up, corporate, or consulting setting.
Core Data Stack: Advanced skills in SQL for data extraction, transformation, and analysis.
Experience working with programming languages such as Python or R for data analysis, manipulation, and API integrations.
Knowledge of database management systems (e.g., BigQuery, MySQL) and experience with ETL processes and tools.
AI & Prompt Engineering: Proven experience or a strong knack for utilizing AI/LLMs (such as Claude) to automate workflows, build internal analytical tools, and optimize business processes.
Data Visualization: You have experience with tools such as Tableau, Looker, Power BI, or similar, and you have strong knowledge of Excel/Sheets.
Business Acumen & Soft Skills: Strong analytical and problem-solving skills, with the ability to translate complex data into actionable insights that drive business value.
The ability to collaborate with business stakeholders to identify information needs, define requirements, and design AI-driven or analytical solutions.
Excellent communication and presentation skills, with the ability to convey complex data and AI concepts to non-technical stakeholders.
It would be a big plus if you:
Have hands-on experience working with Claude (Anthropic) or other major LLMs to automate tasks, generate insights, or build internal prototypes.
Have experience with AI orchestration tools or API integrations (e.g., connecting LLMs like Claude to data pipelines or internal workflows).
Have experience in forecasting, trend analysis, and predictive modelling.
Have previous experience presenting and communicating data analysis results and insights to external stakeholders.
This is a defining moment to join Seedtag, a company that combines scale, ambition, and soul.
Growth & Opportunity: Accelerated, hands-on development with real ownership, global projects, and internal mobility.

Learning & Development: Access to online learning, continuous training, and optional English or Spanish group classes.
Culture that Cares: Well-being is part of how we work, supported by initiatives like SeedDay, Digital Disconnection, and team-building moments.
