ppbSmadex /b 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. /p pAs 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 bAI RD Effectiveness Lead /b - 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. /p pThis is a bfoundational RD role /b 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. /p pbThis is a full-time position based in Barcelona. /b /p h3Key Responsibilities /h3 h3Build vs Buy - ROI Decision Framework /h3 ul liOwn 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 /li liProduce rigorous ROI analyses for AI investment - quantified, tracked against actual outcomes, and iterated over time /li liMaintain 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 /li liWork alongside the SVP to stress-test recommendations before they are presented to business stakeholders /li /ul h3Production-Grade AI Development /h3 ul liDesign and build AI agents, webhook integrations, MCP connections, and agentic workflows to production standards /li liApply security-first and efficiency-first principles to every build: least privilege, observable outputs, sustainable maintenance overhead /li liProduce clean,



well-documented solutions that others can understand, maintain, and build on - not black-box prototypes /li liOwn the technical handover to the Enablement Lead for every build that goes into operational use /li /ul h3AI Capability Management /h3 ul liMaintain the AI capability matrix: which models and tools are approved for which use cases, with documented rationale /li liContinuously benchmark new capabilities against Smadex’s actual use cases - not generic industry benchmarks /li liTrack model and tool end-of-life proactively; recommend transitions before performance degrades /li liKeep the team from quietly running on outdated or cost-inefficient models /li /ul h3RD and Innovation /h3 ul liOwn the forward-looking RD function: horizon scanning, prototyping, and translating emerging AI capabilities into Smadex-relevant proof of concepts /li liLead structured innovation initiatives - hackathons, rapid prototyping sprints - working cross-functionally to generate and validate ideas /li liBrief the team and Enablement Lead on what is coming in the AI landscape that is relevant to Smadex’s commercial and operational context /li /ul h3What we are looking for /h3 ul li4–7 years of experience in AI engineering, solutions architecture, technical product, or a similar hands-on builder role /li liProduction AI build experience: agents, automations, API integrations, or agentic workflows shipped to a real production environment - not just prototypes /li liSecurity and efficiency mindset: designs for least privilege, observable outputs, and maintainability from the start, not as an afterthought /li liStrong analytical capability: able to construct an ROI framework, quantify trade-offs,



and communicate a build recommendation clearly to non-technical stakeholders /li liFamiliarity with the business SaaS ecosystem: Salesforce, Slack, Notion, or similar - and how AI layers onto commercial and operational workflows /li liBonus: Experience with MCP architecture, webhook design, or agentic workflow patterns /li liBonus: Background in adtech, DSP, or programmatic - domain fluency shortens the calibration period /li liBonus: Exposure to AWS Bedrock or equivalent managed AI services /li liA portfolio of things you have actually shipped carries more weight than any certification. We are looking for someone who has moved from idea to production on something AI-powered and who can explain exactly why some builds break in the real world. /li /ul h3Why this role matters: /h3 pThis is not an AI tools evaluation role. /p pIt is the function that decides what Smadex’s AI is worth doing and makes sure it gets done properly. You will own the RD capability for a fast-moving, commercially ambitious business unit - building the agents and workflows that compound over time, and making the investment decisions that ensure we are never building the wrong thing for the wrong reason. /p pIf you are a rigorous thinker who can also ship - and who finds it energising to work at the boundary of analysis and construction - we’d love to meet you. /p pbPlease note that we do NOT provide VISA sponsorship. Candidates without a legal permit to work in Spain won't be considered. /b /p h3What is in it for you: /h3 ul liIntegrate a highly motivated, young and dynamic team /li liGreat compensation package /li liTop location at the heart of Barcelona with a rooftop terrace, Barbecue, and a fully stocked fridge /li liGreat work-life balance: work from home (2 days per week), adaptable hours /li liMeal vouchers - Ticket Restaurant monthly allowance /li liMonthly gym allowance: Choose between DiR and Wellhub /li liLinkedIn Learning and training opportunities /li liMonthly TGIF events /li liRegular team-building events /li liFun and friendly work environment with talented marketers and engineers from over 40 countries /li /ul /p #J-18808-Ljbffr
