Senior Solutions Architect

Join Kargo as a Senior Solutions Architect, where you will be the technical authority responsible for integrating new advertising surfaces into our platform. You will work at the intersection of engineering, partnerships, and product, owning custom code, SDK work, and troubleshooting. Your success will be measured by timely and high-quality partner integrations, scalable custom integration solutions, fast technical troubleshooting, and comprehensive documentation. You should have 5+ years of experience in a technical ad tech role, advanced JavaScript proficiency, and deep fluency in the programmatic ecosystem.

• Assurer l'intégration réussie de nouveaux partenaires sur la plateforme Kargo, en respectant les délais et en garantissant la qualité.
• Développer des solutions d'intégration personnalisées qui sont évolutives et réutilisables, en documentant et en maintenant le code, les SDK et les modèles d'intégration.
• Fournir un support technique de haut niveau aux partenaires, en diagnostiquant et en résolvant rapidement les problèmes complexes liés à la diffusion d'annonces.
• 5+ years in a technical ad tech role — integrations, solutions engineering, or technical account management — with hands-on implementation experience, not just oversight
• Methodical debugging and troubleshooting approach across web, mobile, and desktop environments using standard web tools and platform-specific log analysis
• Proven partner-facing communication skills — can translate complex technical concepts clearly for both engineering counterparts and non-technical business stakeholders without losing accuracy
• REST API experience — designing against, debugging, and integrating via REST endpoints and JSON data structures for both client-server and server-to-server communication
• Advanced JavaScript proficiency for custom integration logic and non-standard DOM manipulation; strong HTML and CSS for ad rendering and placement in overlay and interstitial contexts
• Deep fluency in the programmatic ecosystem — SSPs, DSPs, ad servers (Google Ad Manager), VAST/VPAID, header bidding/Prebid — and how these components interact in non-standard environments
• Experience integrating non-traditional or emerging ad surfaces — gaming, CTV, desktop applications, or other environments outside standard display and video
• Familiarity with IAB standards, privacy compliance frameworks, and technical audit/QA processes for ad delivery
• Takes end-to-end responsibility for integration quality — from scoping to launch to post-live stability — without needing a project manager to hold the thread
• Comfortable building integrations into environments that don't have a playbook yet; figures it out methodically rather than waiting for guidance
• Manages partner complexity and competing timelines without drama — keeps integrations moving even when requirements shift mid-stream
• Earns trust with technical and non-technical partner stakeholders quickly; sets realistic expectations and follows through consistently
• Works fluidly across product, BD, and sales to scope feasibility and surface blockers early; translates between business intent and technical reality in both directions
• Brings useful signal back from the field — partner feedback, integration friction, emerging surface patterns — that informs product and platform decisions
• Writes integration guides and API specs that other engineers can actually use — clear, complete, and maintained as surfaces evolve
• Treats knowledge transfer as a core deliverable, not an afterthought; actively reduces single points of failure in partner knowledge
