What you will be doing:

Data Cleaning & Tracking

• Identify, label, and track raw point-cloud data from studio shoots, manually fixing marker swaps or mislabeled tracking points.
• Reconstruct missing data points caused by actor occlusions (e.g., when a limb is hidden from cameras) using interpolation, smoothing algorithms, or reference footage.
• Remove jitter, spikes, and artifacts from raw tracking curves while preserving the subtle nuances and weight of the original performance.

Skeletal Solving & Retargeting

• Solve processed marker data onto 3D character rigs, ensuring the performance translates accurately despite proportional differences between the actor and the 3D model.
• Correct structural clipping, stabilize feet to eliminate floor-sliding, and fix basic posture/interaction anomalies.
• Sync cleaned data with reference video to ensure the digital character perfectly retains the actor's emotional intent, timing, and weight distribution.

Pipeline & Organization

• Meet strict production deadlines to ensure a steady stream of clean data is handed off to the character animation and cinematic layout teams.
• Fix all structural issues introduced during retargeting, including hand/foot sliding, floor penetration, clipping (limbs passing through clothing/body), and unnatural joint stretching.
• Apply traditional keyframe animation layers to amplify poses, sharpen timing, fix off-balance center-of-gravity issues, and push the performance to match stylized or cinematic art directions.
• Adjust animation curves to ensure flawless contact and interaction with virtual props, weapons, vehicles, and uneven terrain geometry.

What we are looking for:

Technical Skills & Experience

• Advanced proficiency in data-cleanup and retargeting software, such as Autodesk MotionBuilder and Vicon Shogun Post
• Solid understanding of Autodesk Maya and how animation curves function within engines like Unreal Engine or Unity.
• A deep understanding of human anatomy, weight distribution, and realistic movement to accurately infer missing data.
• Experience: 3–5 years of experience in a cleanup, tracking within video games production.

Soft Skills & Core Competencies

• Exceptional patience and attention to detail for handling repetitive, meticulous vector data manipulation.
• Ability to visually reconstruct complex movements when large chunks of camera data are missing.
• Highly organized workflow to efficiently handle large volumes of performance files under tight schedule constraints.
• Advanced proficiency in traditional 3D keyframe animation, with a deep understanding of animation curves, graph editors, Euler angles, and gimbal lock resolution.
• Solid command of weight, anticipation, staging, arcs, and secondary action to naturally enhance captured data without making it look "floaty" or robotic.
• Deep understanding of Forward Kinematics (FK) and Inverse Kinematics (IK) systems, and how character rigs behave when handling external constraints.
• Ability to interpret a director’s creative notes and translate performance critiques into technical animation adjustments.
• Knowing exactly when to preserve the organic nuance of the actor's performance and when to overwrite it with keyframes for the sake of gameplay responsiveness or cinematic clarity.
