• Practical experience with AI developer tools (e.g. Claude GitHub Copilot Cursor Codex Kiro) including evaluating adoption usage depth and impact on developer workflows and outcomes.

• Strong cross‑functional collaboration skills: able to partner with marketing product data science architecture and legal to make high‑quality trade‑offs

Preferred qualifications:

• Experience with marketing technology ad platforms or growth/optimization stacks

• Active immersion in the AI ecosystem – relationships with frontier labs agent platforms or AI-native startups treated as a meaningful signal of genuine engagement not just familiarity.

• Familiarity with AI/ML in production—model integration patterns evaluation safety guardrails

• Comfort operating in pre‑playbook spaces where hypotheses will be wrong experiments will fail and rapid iteration is required.
