2D/3D Character Animation & Motion Graphics (Interactive Web)

About the job

HeartStamp is a pre-series A capitalized startup developing a first-of-its-kind generative AI platform, with an MVP set to launch in December. Our mission is to empower creativity by enabling users to produce unique, high-resolution generative images and videos. Our platform features a sophisticated hybrid AI engine and will be powered by a vibrant creator economy.

We are seeking a 2D/3D Character Animation & Motion Graphics who can blend animation, motion design, and interactive graphics into delightful web-based experiences.

About the Role

This role bridges 2D motion graphics, 3D character animation, and real-time browser interactivity. You’ll design and animate characters and motion sequences that evolve from 2D prototypes into interactive 3D experiences. You’ll also create motion graphics-driven micro-interactions, playful reveals, and hidden Easter eggs across the landing page and platform — ensuring the overall experience feels polished, engaging, and alive.

Responsibilities

• Design, rig, and animate 2D and 3D characters (Blender, Spine, After Effects, or similar).
• Create motion graphics sequences (transitions, reveals, effects) for the platform and landing page.
• Design 2D interactions and create animation concepts that can translate into real-time 3D behaviors.
• Design physics-inspired systems (bounce, collisions, elasticity) that feel playful and responsive.
• Design Easter eggs, hidden moments, and fun micro-interactions across the platform.
• Optimize assets, animations, and pipelines for smooth performance across browsers and devices.
• Collaborate with product/design to define the style, personality, and polish of interactive animations.

Requirements

• Strong background in motion graphics and 2D animation (After Effects, Spine, or equivalent).
• Proficiency in 3D modeling, rigging, and animation (Blender, Maya, etc.).
• Understanding of physics-based interactions in interactive graphics.
• Proven ability to design delightful Easter eggs, motion-driven micro-interactions, and playful animations.
• Ability to design animations and visual cues that simulate interactivity (e.g. bounce, stretch, reactive effects). Actual haptic feedback and input handling will be implemented by our developers.
• Ability to optimize motion graphics and 3D animation for cross-browser and multi-device experiences.

Nice to Have

• Shader programming, lighting, and material expertise.
• Familiarity with game engines (Unity, Unreal) and web workflows.
• Background in interactive storytelling or character-driven design.
