Job Description & How to Apply Below
Client:
Large Fortune 500 Enterprise
Duration: 6-month contract
Rate: ~$70-$75/hourly
Team: MAIBA - Business Experiences (Content Design / Model Design)
About the Role
We're looking for a Model Designer to help shape the next generation of AI-driven Ads experiences for a large Fortune 500 enterprise client.
This is a unique opportunity at the intersection of content design, conversational UX, and AI systems. You'll define what high-quality AI interactions look like-and translate that vision into the model instructions that drive real behavior.
This role blends strategy and execution. You won't just follow specs-you'll help create them, using evaluation data and experimentation to continuously improve how the model performs.
What You'll Do
Define and evolve conversation design frameworks (tone, structure, clarity, actionability)
Translate design principles into system prompts and model instructions
Iteratively improve language-driven model behavior (responses, follow-ups, edge cases)
Use evaluation data (judge scores, testing results) to guide design decisions
Partner with Product, Engineering, and Design to align on quality standards
Test and dogfood model outputs to catch issues early
Work in a 4-week sprint cycle, continuously refining and improving performance
What We're Looking For
Strong experince in content design, UX writing, or conversational design
Experience working with LLMs or prompt design (writing and iterating on prompts)
Ability to think end-to-end about user conversations, not just individual responses
Comfortable operating in ambiguity and defining "what good looks like"
Experience using data or evaluation signals to iterate and improve outcomes
Strong cross-functional collaboration skills
Nice to Have
Experience in Ads or performance marketing
Experience in AI conversation design or model design
Familiarity with information architecture or structured content systems
Why This Role
You'll help define an emerging discipline-model design-inside a large-scale enterprise environment. Your work will directly impact how AI systems communicate with advertisers, shaping both the user experience and model behavior at scale.
