• Strong communication skills, a collaborative mindset, and commitment to creating inclusive environments where all voices are valued.

BONUS POINTS

• Prior experience in ad tech, media planning systems, or programmatic advertising platforms.
• Experience designing skill-based or MCP tool sets for autonomous agents.
• Experience building, tuning, and evaluating production-grade agentic systems. Preference towards patterns such as asynchronous agents and event driven systems.
• Familiarity with prompt engineering, structured outputs, and techniques for improving agent reliability.
• Experience with RAG systems, vector databases, or knowledge retrieval approaches.
• Background in building developer tools, SDKs, or API-first products.
