The AI Character Designer will serve as a creative technologist responsible for designing and optimizing AI-generated characters within an end-to-end content generation pipeline. This role sits at the intersection of storytelling, generative AI, and video production, with a strong emphasis on building scalable character systems that power short-form, AI-generated video experiences. You will define and refine character frameworks, behaviors, and personas that enable AI systems to consistently generate compelling, cohesive dialogue and visual outputs. This is a highly iterative, systems-driven role requiring both creative storytelling instincts and technical fluency with AI tools.
Job Responsibility:
Design and define AI-generated characters, including visual traits, voice, tone, personality, and interaction patterns, ensuring consistency across all generated content
Develop detailed character frameworks and creative briefs that guide AI systems in generating structured, high-quality scripts and video outputs
Build and refine AI personas (e.g., character voices, screenwriter personas, production personas) that drive script and video prompt generation
Evaluate AI-generated scripts and videos, identifying issues such as character drift, inconsistent tone, or unnatural dialogue, and trace root causes across the system
Continuously improve character consistency and performance by refining prompts, constraints, and system rules
Establish and manage quality control frameworks, including character continuity, dialogue pacing, and content validation checks prior to video generation
Define and evolve evaluation criteria and scoring rubrics focused on character performance, including consistency, believability, and engagement
Collaborate cross-functionally with UX, product, and engineering teams to align character-driven content with broader user experience goals
Operate in a fast-paced, experimental environment with rapid iteration cycles and direct impact on customer-facing experiences
Requirements:
Strong familiarity with generative AI tools, including LLMs for script generation and video/image models for visual output
Experience with character design for visual or narrative media (animation, illustration, or character-driven storytelling)
Proven experience with prompt engineering, including iterating on structured inputs to improve consistency and quality of AI outputs
Ability to critically evaluate AI-generated content and articulate specific issues such as character inconsistency, tone mismatch, or pacing breakdowns
Systems-thinking mindset with the ability to design and optimize multi-step creative pipelines rather than one-off outputs
Experience writing for spoken dialogue, such as screenwriting, voice-over, or audio-first content formats
Comfort working with structured data formats such as JSON, markdown templates, and timing frameworks
Working knowledge of video production fundamentals, including framing, pacing, lighting, and camera direction
Highly self-directed with the ability to independently identify issues, iterate on solutions, and improve system performance
Nice to have:
Background in streaming, entertainment, or content recommendation systems
Familiarity with text-to-speech (TTS) systems and how script structure impacts synthesized voice quality
Experience building or managing scalable creative systems, including templates, style guides, and quality assurance frameworks
