Core Responsibilities

Primary Functions

Design, implement, and maintain scalable real-time animation systems and middleware (animation state machines, blending trees, layered animation controllers) to support complex character behavior across multiple platforms.
Architect and implement high-performance runtime animation code in C++ (or engine-native language), optimizing memory usage and CPU/GPU cost to meet frame-rate budgets on console, PC, and mobile platforms.
Integrate animation systems into game engines (Unreal Engine, Unity, proprietary engines): implement animation blueprints, animation graph nodes, custom runtime components, and editor extensions to expose functionality to animators and designers.
Collaborate with animators and technical artists to define animation pipelines and data formats (skeletal data, animation clips, clip metadata, retargeting rules) that preserve artistic intent while enabling runtime flexibility.
Create and maintain robust retargeting, retime, and compression solutions for skeletal animation to minimize storage costs and preserve motion fidelity across character rigs.
Implement inverse kinematics (IK) solutions, procedural animation systems, and locomotion controllers (foot placement, root motion, slope handling) to increase realism and responsiveness.
Build and optimize ragdoll, physics-blended animations, and joint constraints, ensuring smooth transitions between physics-driven and keyframed animation states.
Develop procedural animation tools and solvers (e.g., procedural walk cycles, aim offsets, dynamic secondary motion) to reduce manual authoring overhead and improve animation variation.
Author and maintain editor tools and pipelines (Maya/Max export scripts, FBX/HAVOK/Houdini integration, automated importers) that accelerate animation import, validation, and iteration for production artists.
Implement and tune animation blending, layering, and masking systems with priority, weight, and synchronization controls to support complex character behaviors and gameplay-driven overrides.
Design and enforce animation metadata standards (events, notifies, tags) that enable runtime gameplay hooks, audio/sfx triggers, and analytics for motion-related systems.
Collaborate with gameplay, combat, VFX, and audio teams to sync animations with gameplay states and ensure deterministic behaviors across networked multiplayer scenarios.
Profile, benchmark, and optimize animation code paths and data formats; identify hotspots and refactor algorithms to reduce per-frame cost while preserving animation quality.
Lead technical design reviews for character and animation features; evaluate trade-offs between memory, CPU, and artistic fidelity in feature proposals.
Implement and maintain automated test suites, validation checks, and smoke tests for animation asset integrity and runtime stability across engine versions and platforms.
Troubleshoot and debug complex animation issues (popping, sliding, root offset drift, clipping) using engine debug tools, frame captures, playback scrubbers, and logging.
Integrate and maintain third-party animation middleware and solutions (e.g., motion-matching systems, Maya/Houdini toolsets, physics engines) and customize them to meet project needs.
Provide production support for pipeline bottlenecks: automate repetitive manual tasks, create batch processing utilities, and optimize asset import/export workflows.
Mentor junior programmers and technical artists on animation systems, rigging best practices, and engine integration patterns to improve team-wide expertise and throughput.
Drive continuous improvement by researching state-of-the-art techniques (motion capture processing, motion matching, machine learning for animation, procedural physics) and proposing practical adoption paths.
Document architecture, APIs, editor features, and pipeline conventions; write onboarding guides and examples to help artists and engineers quickly adopt systems.
Collaborate with QA to reproduce and fix animation regressions and platform-specific issues; ship patches and hotfixes as necessary for milestones and releases.
Plan and estimate animation feature work, participate in sprint planning, and communicate progress and technical risks to producers and stakeholders.

Secondary Functions

Support ad-hoc animation and rigging requests from artists and designers; implement quick iteration tools or hotfixes to unblock production.
Contribute to the cross-disciplinary roadmap for character systems, proposing measurable KPIs for animation performance and quality.
Build small demo prototypes to validate motion systems, interaction models, and engine constraints prior to full production integration.
Maintain versioned toolsets and ensure backward compatibility for animation assets across engine upgrades.
Assist in recruitment by evaluating technical skills of candidates for animation programming and technical art roles.
Participate in postmortems and retrospectives to capture lessons learned and document best practices for future projects.
Offer time-boxed support to external contractors and outsourced animation partners to ensure their deliverables meet engine and pipeline requirements.
