Forward Deployed Engineer (EMEA)

Solutions Engineer About CloudX At CloudX we’re building a new supply-side advertising platform for mobile publishers. We’re convinced that an AI-native product will significantly advance the state of the art in mobile advertising; we recently raised a $30M Series A in order to bring this dream to life. We have a long history of innovation in this space — our founding team previously built MoPub (sold to Twitter for $350M) and MAX ( acquired by AppLovin ). Our new platform combines real technical improvements like verifiably fair auctions with a truly AI-native product experience to give publishers unprecedented control over their ad monetization strategy. The Role Own the complete technical relationship with publishers and demand partners—from pre-sales solution design through hands-on integration and ongoing optimization. Combine deep ad tech expertise with consultative problem-solving to ensure partners extract maximum value from CloudX's platform What You'll Do Lead technical discovery and solution design during pre-sales engagements with all regional publishers and demand partners Own SDK integration from kickoff to first impression served, ensuring smooth technical onboarding Provide real-time technical support during integration, QA, and optimization phases Troubleshoot technical issues across the ad delivery pipeline - SDK, auctions, bidding, reporting Build automation tools, AI agents, and scripts to scale integration support and partner enablement Leverage AI to analyze integration patterns, predict potential issues, and generate technical documentation Collaborate with Product and Engineering to translate partner feedback into platform improvements and AI-powered features Create and maintain technical documentation, integration guides, and best practice playbooks using AI assistance Monitor partner technical health and proactively identify optimization opportunities using data analysis and AI insights What You Bring 5+ years experience in ad tech as Solutions Engineer, Integration Engineer, or Software Engineer focused on platform integrations Proven ability to lead complex technical integrations with enterprise clients, ideally in mobile, SDK-based, or programmatic advertising environments Strong proficiency in iOS (Swift, Objective-C) and Android (Kotlin, Java) for SDK integration support Deep understanding of ad tech ecosystem: mediation platforms, header bidding, RTB/OpenRTB, auction mechanics, ad servers Strong troubleshooting and debugging skills across client-side and server-side systems Hands-on experience using AI tools (like Claude) to enhance productivity - code generation, debugging, documentation, log analysis Ability to build AI-powered automation tools and scripts that scale your impact beyond manual work Excellent communication skills - can explain complex technical concepts to both technical and non-technical audiences Experience with BI/analytics tools (Looker, Tableau, Databricks) What We're Looking For Hands-on technical expertise: You've been directly working on complex ad tech integrations and solutions, not just managing projects. You can write code to solve problems - whether it's debugging an SDK issue, building an automation script, or creating a custom Lambda function. You're comfortable diving into logs, analyzing bidstream data, and architecting solutions. Consultative mindset: You're not just an implementer - you're a trusted technical advisor. You ask great questions to understand publisher needs, design solutions that balance requirements with platform constraints, and guide partners toward optimal outcomes. Bridge builder: You translate between technical and business worlds effectively. Problem-solving: When integrations break or partners face issues, you form hypotheses, test them methodically, and communicate clearly throughout. You don't just fix the immediate problem - you identify root causes and prevent future occurrences. High ownership and initiative: You own partner technical success end-to-end. When you spot opportunities to improve our platform or processes, you build prototypes, document proposals, and drive change. Early-stage mentality: You thrive in ambiguity and move fast. You know when "good enough" is better than perfect and when to advocate for rigorous solutions. You're comfortable wearing multiple hats - one day doing hands-on integration work, the next presenting to executives, the day after that building automation tools. AI-forward approach: You actively use AI tools to scale your impact - analyzing logs, debugging code, creating documentation, building automation. You understand what AI can help with and where human expertise is critical. You're excited about building AI-powered solutions for partners. Why This Role Your ad tech experience has given you unique insights into what makes integrations succeed or fail, what partners actually need vs. what they ask for, and how to balance technical excellence with business pragmatism. Instead of supporting one platform, you'll shape how an entire market integrates with next-generation ad infrastructure. When you identify systematic partner challenges, you'll work directly with our product and engineering teams to solve them at scale. Your technical guidance will directly impact millions in ad revenue for our publishers. What We Offer Competitive salary + equity + benefits Remote work flexibility with follow-the-sun coverage model Work directly with MoPub/MAX founding team Shape the future of ad tech infrastructure
