About the role

  • Lead 3D Animator to build and own the pipeline for rigging and animating low‑poly 3D characters, rendering clean frame sequences, and authoring production‑ready Spine animations for use in Unity 3D.
  • Hands‑on across the entire flow—from low‑poly character rigging and motion, to render standards, Spine skeleton setup (IK/constraints/weights/skins), and final integration.
  • Define the 3D‑to‑2D render pipeline, build Spine skeletons, prepare sprite sheets/atlases and Spine exports, and establish workflows and documentation.
  • Create deformation‑aware character rigs, animate game‑ready cycles and cinematic moments, and drive render consistency for readability in atlases.
  • Integrate Spine content into Unity, collaborate with designers and VFX, and evaluate/adopt tools and automation to improve productivity.

Requirements

  • 5+ years in character animation for games or interactive content, with shipped titles or live products.
  • Expert rigging & keyframe skills in Blender or Maya (controllers/constraints, deformation, skinning) focused on low‑poly stylized characters.
  • Production experience creating Spine rigs and animations: bones/IK/constraints, meshes/weights, skins, dopesheet/graph editing, track mixing, events, and exports for runtime.
  • Proven 3D→2D render pipeline experience (frame sequences/sprite sheets) optimized for mobile (atlas packing, memory/perf constraints).
  • Strong animation fundamentals (timing, spacing, arcs, weight, anticipation, follow‑through) and motion readability at small screen sizes.
  • Clear documentation and spec writing for engineers (states, events, naming, asset maps).
  • Nice‑to‑Have: Unity real‑time animation systems, Spine‑Unity runtime customization, shaders, addressables/asset bundles, Python/MEL, simple C# familiarity.
