Our influencer marketing platform, Popular Pays, provides creators the ability to monetize their work and offers brands opportunities to scale their content through tailored creator partnerships.

We are  seeking a Senior Researcher to join our LTX Render Lab team at Lightricks. This team is responsible for developing cutting-edge 3D technology to power state of the art video generation, enabling immersive and dynamic content creation. As a key member of the team, you will lead research efforts in 3D reconstruction, dynamic scene interaction, and multi-view video consistency, driving the transition from early prototypes to scalable, production-ready solutions.

What you will be doing

• Conduct applied research in 3D reconstruction, scene creation, and animation.
• Develop algorithms for placing characters and objects dynamically within 3D spaces.
• Explore multi-view video consistency and advanced camera control for scene animation.
• Optimize research code for scalability and real-time performance.
• Collaborate with engineers, designers, and product managers to integrate 3D capabilities into user-facing features.
• Stay up to date with cutting-edge academic research and apply relevant innovations to production.
• Write high-quality code, ensuring research solutions are optimized for real-world applications.
• Mentor junior researchers and contribute to knowledge-sharing initiatives within the team.

Your skills and experience

• M.Sc with 5+ years of industry experience in computer graphics or computer vision
• Strong expertise in 3D geometry, rendering pipelines, and computer vision (e.g., multi-view geometry, neural radiance fields, point-based rendering).
• Deep understanding of modern AI/ML techniques for image/video generation and reconstruction.
• Proficiency in Python and/or C++ for high-performance algorithm development.
• Experience transitioning proof-of-concept research into scalable production-ready solutions.
• Strong ability to collaborate with interdisciplinary teams and communicate complex research findings effectively.

Preferred Requirements

• Experience with game engines (Unreal, Unity) or 3D libraries (Panda3D, Three.js).
• Familiarity with Gaussian splatting, neural rendering, and dynamic scene construction.
• Prior experience with character animation, rigging, or AR/VR applications.
• Understanding of cloud-based infrastructure for large-scale training or real-time inference.
