We leverage modern machine learning technologies, to address 3D models, 3D scenes, Animation, Rendering, and to tackle challenging computer graphics problems that no conventional technique can solve. We are committed to pioneering new frontiers in technology, ensuring remains at the forefront of innovation in the industry.

We are looking for talented individuals to join our team in 2026. As a graduate, you will get opportunities to pursue bold ideas, tackle complex challenges, and unlock limitless growth. Launch your career where inspiration is infinite at TikTok.

Successful candidates must be able to commit to an onboarding date by end of year 2026. Please state your availability and graduation date clearly in your resume.

Applications will be reviewed on a rolling basis - we encourage you to apply early.

Responsibilities:

  • Design and implement advanced algorithms for 3D generation/editing, real-time physics simulation, character animation, geometric modeling, rendering etc.

  • Develop and integrate deep learning models that enhance speed, fidelity, or realism in physically based simulations or complex graphics workflows.

  • Optimize algorithms and systems for speed and scalability across a wide range of hardware and platform targets.

  • Work closely with product or other engineering teams to identify key challenges and deliver seamless, high-impact graphics solutions.

  • Stay up to date with the latest research in computer graphics, physics simulation, and machine learning.

  • Contribute to internal knowledge-sharing and may publish findings in leading conferences or journals.

Qualifications

Minimum Qualifications:

  • PhD in Computer Science, Applied Mathematics, or a related field, with a focus in computer graphics, physics simulation, animation or AI/ML.

  • Mathematical Foundations: Strong background in linear algebra, calculus, geometry, and numerical methods.

  • Computer Graphics: Solid experience in one or more of the following: neural rendering (NeRF, 3DGS, or similar), physically based simulation, animation system, AI.

  • Programming Skills: Proficiency in C++ and Python. Familiarity with GPU programming (CUDA, OpenCL, or similar) is a plus, but not required.

  • Machine Learning: Experience with deep learning frameworks (e.g., PyTorch, TensorFlow) and applying neural networks to graphics, simulation, or generative models is a strong plus.

Preferred Qualifications:

  • Relevant publications in top-tier computer graphics, vision, or ML conferences/journals (e.g., SIGGRAPH, ICCV, CVPR, NeurIPS).

  • A solid background in both 3D computer graphics and AI is preferred.
