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.

Must-haves

  • Experience shipping production software for AI-assisted or other complex, multi-step products.
  • Hands-on experience building agentic applications or orchestration layers that use tools, state and evaluation—not only standalone prompts or demos.
  • Ability to design, debug and operate reliable software services and integrations.
  • Sound engineering judgment and a collaborative approach to ambiguous product problems.

Nice-to-haves

  • Experience with image or video generation, video-editing workflows, or creative tooling.
  • Experience designing agent evaluations, observability or feedback loops.
  • Experience integrating multiple model providers or media-processing services.
