• Own SDK integrations end-to-end, from kickoff to first impression served, working directly with partners' engineering teams
• Provide responsive, hands-on technical support during integration, QA, launch, and optimization
• Troubleshoot issues across the full ad-delivery pipeline, including SDKs, auctions, bidding, and reporting
• Build automation tools, AI agents, scripts, and reusable solutions that make integrations faster and more reliable
• Use AI to analyze integration patterns, diagnose issues, and create technical documentation and diagnostics
• Turn recurring partner needs into product improvements in collaboration with Product and Engineering
• Create and maintain technical documentation, integration guides, and best-practice playbooks
• Monitor partner technical health and proactively identify performance and optimization opportunities

• Native or professional fluency in Vietnamese and strong professional English

Hands-on technical ownership: You are comfortable diving into code, logs, SDK behavior, and live traffic. You take responsibility for partner technical success from discovery through launch and optimization.

Consultative mindset: You ask thoughtful questions, understand business and technical constraints, and guide partners toward practical solutions.

Bridge builder: You translate clearly between technical and business teams and build trust with partners.

Problem solving: You form hypotheses, test methodically, communicate clearly, identify root causes, and prevent problems from recurring.

High ownership and initiative: When you identify an opportunity to improve the platform or process, you prototype, document, and drive the change.

Early-stage mentality: You thrive in ambiguity, move quickly, and are comfortable switching between integration work, partner conversations, and building reusable tooling.

AI-forward approach: You actively use AI to scale your impact while understanding where deep human judgment and technical expertise remain essential.
