Staff Motion Designer - 3D

Mercury is looking for a Staff Motion Designer to own motion across the brand, from launch films and product videos to the systems and standards that define how motion looks and feels on every surface. This is a senior craft role where you will set the bar through your own hands-on work while helping shape how AI fits into a modern motion practice.

In this role, you'll:

• Lead motion concepts for major product launches, campaigns, and brand moments, with strong 3D capability across product visualization, environments, objects, and brand worlds.
• Build 3D worlds, materials, and textures that give Mercury's biggest launches and brand moments a distinct, recognizable feel.
• Lead product storytelling, title design, typography, transitions, diagrams, and UI motion, turning complex products into simple, compelling visual stories.
• Define and build out Mercury's motion design system: principles for typography, pacing, transitions, product UI, sound, and interaction, plus reusable behaviors and templates.
• Explore motion in interactive contexts, and bring an informed point of view on where AI tooling can extend the team's speed and craft.
• Build and champion AI-assisted workflows for motion and 3D, from generative pre-vis and storyboarding to texture and asset generation.
• Evaluate new AI creative tools as they emerge and make the call on which are worth adopting into the team's pipeline.
• Partner with Design, Writing, Narrative, and Production from concept through delivery.
• Personally lead high-level 3D and motion craft while art-directing specialist animators, 3D artists, and studios.
• Raise the motion craft of the broader Brand Studio through partnership, critique, and example.

What you'll bring:

• 10+ years of professional experience in motion design with a portfolio showing mastery across 3D and 2D.
• Advanced proficiency in Cinema 4D, Houdini, Blender, or similar 3D tools.
• Advanced proficiency in After Effects or similar 2D motion tools.
• Experience building and documenting motion systems or brand guidelines.
• Comfort moving between big, high-craft brand moments and faster-moving product/UI and social work.
• A track record of art-directing or mentoring other designers, animators, or outside studios.
• Genuine fluency with AI tooling as part of a creative practice.
• Strong communication skills to clearly articulate concepts and creative decisions.
• Exposure to scripting or procedural workflows (expressions, Houdini VEX, Python) is a strong plus.
