What you’ll do:

Elevate Reddit's Generative Creative Systems:

• Build and maintain a robust library of gen AI prompts and creative patterns aligned with Reddit’s ad formats, community dynamics, and creative best practices.
• Translate advertiser goals and campaign strategy into structured, machine-readable inputs that produce effective and contextually relevant assets.
• Expand the coverage of reddit’s creative generators to all the relevant formats and placements in the platform, following the best practices for performance and adoption.
• Define a versioned prompt/input taxonomy (objective, audience, tone, constraints, community signals) with tagging for format, vertical, and outcome.
• Instrument coverage tracking to expose gaps by format, placement, and vertical; publish a prioritized backlog to close gaps.

Optimize Model Outputs Across Creative Surfaces:

• Improve the quality, contextual relevance, and brand safety of large language and diffusion model outputs across text, images, video, contextual variations, and personalized variants.
• Develop a repeatable framework for evaluating model outputs, iterating on prompts, and refining input data.

Accelerate GenAI Experimentation and Product Velocity:

• Establish a consistent, weekly cadence for model testing, structured feedback, and creative experimentation.
• Partner with Product and Engineering to prioritize improvements, validate model updates, and accelerate feature development by 4–6 weeks per launch.

Operationalize Agentic and Automated Creative Workflows:

• Identify opportunities to automate creative actions, such as generating asset variations, enhancing client-provided media, or informing creative recommendations.
• Collaborate on integrating creative-audience insights signals into generative inputs.

Who you are:
