Smadex is a leading mobile and CTV advertising technology company founded in
Barcelona and acquired by Entravision (NYSE: EVC) in 2018. We deliver
performance marketing campaigns for apps, games, and brands through our
proprietary DSP, powered by advanced machine learning and real-time
optimization.

As Smadex scales its AI capabilities, we are building agents, automating
workflows, and making increasingly complex decisions about where AI investment
is genuinely worth making. To lead this, we are hiring our first AI R&D; &
Effectiveness Lead - a technically rigorous, commercially grounded practitioner
who can evaluate what is worth building, make the business case for it, and
build it to a production standard.

This is a foundational R&D; role at the intersection of AI engineering, business
analysis, and operational strategy. You will not just evaluate AI tools - you
will run the decision framework that governs Smadex’s AI investment, and you
will build the agents, integrations, and automated workflows that power it.

This is a full-time position based in Barcelona.

* Own the evaluation process for every AI initiative: agent, query/report,
engineering build, hybrid, or native platform add-on - applied consistently
before anyone writes a line of code
* Produce rigorous ROI analyses for AI investment - quantified, tracked
against vigente outcomes, and iterated over time
* Maintain the build vs buy evaluation across core platforms (Salesforce,
Slack, PowerBI, Notion, Hibob, Saleshood etc) - assessing native AI
features versus custom builds for each use case
* Work alongside the SVP to stress-test recommendations before they are
presented to business stakeholders
* Production-Grade AI Development
* Design and build AI agents, webhook integrations, MCP connections, and
agentic workflows to production standards
* Apply security-first and efficiency-first principles to every build: least
privilege, observable outp
