Smadex seeks a Creative Technologist (Playable Ads Developer) 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, end-to-end testing and QA, cross-functional leadership, client enablement, and knowledge management. Responsibilities include building scalable ad templates, designing mobile-first UX, optimizing for ad constraints, defining test matrices, debugging SDK and ad delivery issues, automating QA processes, coordinating between teams, supporting client conversations, and maintaining a creative repository. Requirements include 3-7+ years in creative technology for mobile interactive ads, a strong playable ads portfolio, expertise in frontend technologies and mobile playable tools (Phaser, Pixie, Unity, Cocos, Playable Factory), experience in QA and troubleshooting, ability to implement event tracking, and commercial awareness in the App AU ecosystem. Good to have are skills in 3D mobile web experiences, SIMID for CTV, cross-functional collaboration, mobile E2E testing, programmatic ad serving knowledge, and graphics optimization. The position is full-time, hybrid (3 days co-working, 2 days remote), based in London, with competitive remuneration, health insurance, training opportunities, and travel to Barcelona HQ for team activities. Visa sponsorship is not provided.

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: 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, 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/Pixie, 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
  • Good to have: Experience building 3D interactive experiences on mobile web
  • Good to have: Experience building SIMID for CTV interactive
