Full job description

Smadex, a Barcelona-based Demand Side Platform, is seeking a senior Game Developer (Playable Ads) to build high-performing interactive and playable mobile and CTV ad experiences. Reporting to the Director of Creative Solutions, the role involves developing playable ad technology, ensuring end-to-end testing and QA, leading cross-functional collaboration, and managing knowledge and best practices. Candidates must have 3-7+ years of experience in creative technology for mobile interactive ads, a strong portfolio of playable ads, expertise in frontend technologies and mobile playable tools (Phaser, Pixi, Unity, Cocos, Playable Factory), and experience with QA and ad delivery. The position is full-time, hybrid (2 days remote), located in Barcelona, and requires legal work authorization in Spain. Benefits include private health insurance, LinkedIn Learning access, meal vouchers, gym allowance, team-building events, and a modern office environment.

What you'll do

  • Build, architect, and extend high-performing playable ad experiences and interactive creatives for mobile and CTV platforms
  • Translate creative concepts (including complex game mechanics) into functional prototypes and scalable ad templates (fast iteration, production-ready standards)
  • Design mobile-first UX patterns specific to playable ads, including in-ad interaction logic, end-card flows, and call-to-action placement
  • Optimize for playable ad constraints: aggressively manage file size budgets, load times, device/OS compatibility, and platform-specific compliance requirements
  • Define comprehensive test matrices and QA checklists (OS versions, device performance, cross-platform publisher environments, connection conditions)
  • Debug complex issues related to SDK integration, third-party trackers, ad delivery, and in-ad game logic
  • Introduce automation where possible (test harnesses, validation scripts, pre-flight checks) to reduce production risk
  • Act as connective tissue between Creative Design, Software and Services as well as Ad Ops, and Product on playable and interactive ad initiatives
  • Define clear workflows and handoffs to reduce bottlenecks and accelerate time-to-launch
  • Support high-stakes client conversations with technical confidence: feasibility, timelines, QA expectations, and measurement plans
  • Partner with Product on tooling and capability gaps needed to scale playable ad output
  • Build and maintain a playable creative repository: winning game patterns, do/don’t guidelines, specs, QA standards, learnings, and case studies
  • Share insights across teams through internal sessions, documentation, and repeatable templates

Requirements

  • 3-7+ years in creative technology making interactive ads for mobile
  • A strong portfolio of Playable ads that have delivered positive performance against advertiser KPI
  • Demonstrated expertise in relevant frontend technologies and libraries used for building complex interactive experiences/game mechanics under tight constraints
  • Hands-on experience with mobile playable tools (e.g. Phaser/Pixi, Unity/Cocos export, Playable Factory or platform-specific tools)
  • Experience shipping and supporting creatives end-to-end (QA, troubleshooting, mobile ad delivery)
  • Ability to translate performance/measurement needs into clear event tracking + experimentable variants
  • Commercial awareness and client facing experience in the App AU ecosystem
