Luma

Role Description Luma is pushing the boundaries of generative AI, building tools that redefine how visual content is created. We’re seeking an Agent Behavior Designer to help shape the logic, personality, and execution of Luma Agents within our core canvas platform. This is an emerging and highly specialized discipline. While this role does not require shipping traditional full-stack production code, it extends far beyond standard prompt engineering. You will operate at the forefront of agentic engineering, working closely with the agent's core behavior, controlling its logic through sophisticated prompting stacks, and tracing causality across complex codebases and execution logs. You will define optimal user experiences, rigorously test agent behavior to identify suboptimal patterns, and iteratively refine complex prompt stacks to resolve them. The ideal candidate demonstrates meticulous attention to linguistic nuance, possesses the technical proficiency to build Python evaluation harnesses, and exhibits the analytical rigor to iteratively resolve complex behavioral challenges. What You'll Do - Diagnose & Debug: Analyze complex agent traces and system logs to identify the root causes of suboptimal outputs. Trace causality through non-standardized text and prompts to resolve unexpected agent behaviors. - Shape Agent Logic: Architect and refine prompt stacks to align agent behavior with intended outcomes. Oversee context window management and implement tool-calling best practices to ensure optimal agent functionality. - Build Evals & Ground Truth: Develop Python-based scripts and evaluation harnesses for robust quantitative and qualitative testing. Partner collaboratively with the Evals team to define performance baselines and measurement frameworks. - Understand and Advocate for the User Experience: Leverage a deep understanding of language, tone, and user intent to ensure agent interactions are intuitive, highly responsive, and creatively enabling within a media-generation environment. Qualifications - 2-3 Years of Experience: Professional experience in a technology-driven environment, with a strong preference for backgrounds that blend analytical and creative problem-solving with deep linguistic or communicative skills. - Proven AI/Agentic Experience: Demonstrated hands-on experience building AI or agentic workflows within the past two years. Candidates without direct industry experience at an AI company must provide a robust portfolio of personal projects or products demonstrating these capabilities. - Technical Literacy: Ability to manage a local development environment, navigate code repositories, write functional Python scripts, and utilize Git/GitHub. (Shipping production-level product code is not required; submitting PR’s, navigating codebase, and resolving errors is). - Exceptional Command of Language: Advanced proficiency in written communication, with an intuitive understanding of how precise linguistic adjustments impact AI model outputs. In this domain, prose functions as code. - Analytical Persistence & Qualitative Judgment: The persistence to iterate continuously through complex edge cases and the qualitative judgment to discern when a creative tool delivers an optimal user experience. - AI Tool Proficiency: Advanced proficiency with AI coding assistants (e.g., Cursor, GitHub Copilot) and related AI productivity tools. Bonus Points - Experience building and operating Reinforcement Learning (RL) pipelines. - Diverse hybrid backgrounds (e.g., intersections of humanities-focused study/role and Computer Science, Linguistics, or Data Analysis, or deeply technical self-taught endeavors). - Experience with AI media generation, editing, and manipulation across modalities (video, images, 3D). - Deep familiarity with creative workflows and the foundational tools digital artists use to craft visual narratives.

Role Description This is a rare and foundational opportunity to define the visual storytelling for the future of creative AI. As our Senior Motion Designer, you will translate the groundbreaking functionality of our AI models into magical, compelling marketing content and product demos. You will be instrumental in shaping Luma's brand narrative, creating high-fidelity motion work that communicates the power of our technology to millions of users. Location Preference: Remote within Bay Area or Los Angeles. What You'll Do: - Translate product functionality and complex use cases into clear, compelling, and magical motion-driven stories for marketing campaigns, product launches, and social media. - Design and execute high-fidelity product demos and marketing videos that showcase the capabilities of Luma's AI in a visually stunning way. - Collaborate closely with the creative team to develop and execute motion concepts that align with Luma's brand and high bar for aesthetic quality. - Own motion projects from concept to completion, handling storyboarding, design, animation, and final production. - Create a wide range of motion assets, including animated UI for product demos, visual effects, and cinematic sequences that embody Luma's brand. - Operate as a key creative partner and hands-on builder, contributing to a culture of visual excellence and innovation. Qualifications - 5+ years of professional experience in motion design, with a portfolio demonstrating exceptional craft and a strong, distinct visual style. - A proven "builder" with a history of executing high-concept projects and shipping world-class marketing or brand-defining content. - Impeccable taste and an obsession with craft, detail, and aesthetics. - A collaborative team player who thrives in a fast-paced environment and is willing to tackle any task to get the job done. - High agency and the ability to operate with autonomy, taking end-to-end ownership of your work from creative direction to final delivery. - Deep expertise in industry-standard motion design software, particularly After Effects (workhorse) and Figma. - A genuine passion for the creative potential of AI and our mission to expand human imagination. Requirements - Proficiency in 3D motion graphics (Cinema 4D, Unreal Engine are high priorities; Blender, Maya, or Nuke are also valued). - Experience in brand-based advertising or filmmaking. - Experience working directly with generative AI tools in a creative capacity. - A public portfolio that showcases unique, experimental, or non-traditional motion design projects.
