Mercury is a fintech platform providing banking, treasury, and financial workflow solutions for startups and technology companies. The company is building products designed with exceptional craft and care, believing that thoughtful design can transform how people interact with financial tools. You will own motion design at Mercury across all contexts: from launch films and product videos introducing major initiatives, to the systems and standards that define how motion appears across every surface. This is the most senior craft role on the design team, setting the bar through your own work. You will move fluidly between 3D worlds, materials, and textures for high-profile brand moments and day-to-day motion, UI, and interaction work that makes Mercury feel considered everywhere. You'll also help define how AI fits into Mercury's motion practice—using it to accelerate pre-visualization, iteration, and asset generation while knowing exactly where hand-crafted work remains essential. Key responsibilities include: - 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 a distinct, recognizable feel - Lead product storytelling through 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 informed perspective on where AI tooling can extend the team's speed and craft without compromising it - Build and champion AI-assisted workflows for motion and 3D, from generative pre-vis and storyboarding to texture, world, and asset generation - Evaluate new AI creative tools as they emerge and determine which are worth adopting versus which compromise craft - Partner with Design, Writing, Narrative, and Production from concept through delivery as a key cross-functional player on the brand's biggest moments - Personally lead high-level 3D and motion craft while art-directing specialist animators, 3D artists, and studios when additional depth or scale is needed - Raise the motion craft of the broader Brand Studio through partnership, critique, and example - Protect craft and coherence across every moving expression of the brand, from 30-second launch films to UI micro-interactions Requirements: - 10+ years of professional experience in motion design with a portfolio demonstrating mastery across 3D and 2D, showing not just execution but conceptual thinking about how motion should move, feel, and unfold over time - Advanced proficiency in Cinema 4D, Houdini, Blender, or similar 3D tools, including materials, texturing, lighting, and world-building - Advanced proficiency in After Effects or similar 2D motion tools, with deep command of timing, easing, composition, and finishing detail - Experience building and documenting motion systems or brand guidelines, not just one-off deliverables - Comfort moving between big, high-craft brand moments and faster-moving product/UI and social work without losing quality - Track record of art-directing or mentoring other designers, animators, or outside studios - Genuine fluency with AI tooling as part of a creative practice, with clear sense of where it helps and where craft still wins - Exposure to scripting or procedural workflows (expressions, Houdini VEX, Python) is a strong plus - Strong communication skills to clearly articulate concepts and creative decisions to internal teams, leadership, and external partners - Natural leader who thrives in highly collaborative environments where the best ideas drive progress
