## About the role

Brands and agencies spend billions a year on media and still struggle to answer two questions: what is actually working, and what should we do next? Their tools don't help much. Mediaocean is the system of record for what they bought. The DSP is the system of action for how it ran. Nothing owns the why — the decision itself.

## What they're looking for

- Own the end-to-end user experience across Newton's platform — planning, buying, measurement, and the agentic workflows that connect them
- Make complex analytical output — causal models, incrementality results, scenario plans, optimization recommendations — clear and defensible to non-technical decision makers
- Design the approval and control experience for governed action: what an agent is allowed to execute, what a human signs off on, and how a customer sets and trusts those limits
- Stay hands-on: wireframes, high-fidelity design, interactive prototypes, and close pairing with engineering through implementation
- Build and maintain Newton's design system and front-end design standards so the platform stays coherent as products and teams multiply
- Run lightweight research and usability work with customers at brands, agencies, publishers, and platforms, turn what you learn into design decisions and product direction
