Harness Engineer — AI Video Creation
RnB Consultancy
San Francisco, CA, United States
Full-time
Build the systems that make AI-assisted video creation reliable enough for real creative work.
In this role, you will shape how agents plan a project, use generation and editing tools, keep track of creative context, and learn from evaluation and user feedback.
Your work will bridge AI capabilities and the experience creators actually use.
Location: San Francisco, California
Compensation target supplied for this search: $200,000–$300,000 annually
Responsibilities
- Design and improve the agent harness behind multi-step video creation workflows, from planning and asset selection to generation, revision and delivery.
- Build dependable connections between agents, creative tools and model providers; make failures observable and recoverable.
- Manage the context, state and tool permissions needed for longer-running creative tasks.
- Define quality checks and evaluation loops for reliability, controllability and the usefulness of generated outputs.
- Work with product, design and engineering partners to turn creator feedback into better workflows, then measure what changes.
