If you are passionate about graphics programming, rendering engines, and GPU optimization, we invite you to be part of our dynamic and forward-thinking team.

Job Overview :

We are seeking a highly skilled Graphics Programmer to develop custom rendering engines, optimize GPU performance, and work with WebGL and WebAssembly to build high-performance graphics applications for the web. This role requires a deep understanding of low-level memory management, performance profiling, and debugging GPU-related issues to ensure efficient rendering. The ideal candidate will also be responsible for implementing advanced rendering techniques and optimizing graphics performance for web applications.

Key Responsibilities :

- Develop and optimize custom rendering engines for web-based 3D applications.

- Work extensively with WebGL, WebAssembly, and rendering libraries such as Three.js and Babylon.js.

- Implement advanced rendering techniques such as SSR (Screen Space Reflections), screen-space shadows, and global illumination (GI).

- Optimize GPU performance through profiling, debugging, and memory management.

- Handle low-level memory operations for both CPU and GPU.

- Write custom multi-pass shaders using GLSL for real-time rendering.

- Debug and resolve performance and memory issues in a garbage-collected environment.

- Implement real-time animation systems and inverse kinematics (IK) solutions.

- Develop optimized real-time global illumination (GI) solutions.

- Work with threading, mutexes, and atomic operations to optimize performance.

Requirements :

- Strong experience with WebGL, OpenGL ES, Vulkan, and GPU programming.

- Proficiency in JavaScript, TypeScript, and WebAssembly for high-performance graphics applications.

- Deep understanding of rendering pipelines, shading languages (GLSL), and low-level memory operations.

- Experience in performance profiling, debugging GPU issues, and optimizing real-time rendering systems.

- Familiarity with memory virtualization, garbage collection, and efficient resource management.

- Expertise in Chrome Performance Profiler and Chrome Tracing for performance analysis.

- Understanding of Entity Component System (ECS) architecture for structured graphics programming.

- Strong knowledge of multi-threading concepts, synchronization mechanisms (mutexes, atomic operations), and real-time data processing.

- Experience working with low-level web development for optimizing rendering in browsers.

Preferred Qualifications :

- Experience developing custom 3D rendering engines or GPU development tools.

- Familiarity with game engines (Unity, Unreal Engine) and their WebGL/WebGPU integrations.

- Knowledge of real-time physics simulations and procedural generation techniques.

- Background in machine learning for graphics applications (e.g., AI upscaling, neural rendering).

- Experience in HLSL, CUDA, Metal, or DirectX for broader GPU programming exposure.

Work Culture & Schedule :

- Work Days: Monday to Friday (Work from Office) & Saturday (Work from Home).

- Work Timings: 10:00 AM onwards.

- Dynamic and collaborative work environment where creativity and innovation thrive.

- Opportunities for continuous learning and development in cutting-edge graphics technologies.

Benefits :

- Competitive salary with performance-based bonuses.

- Career growth opportunities, training, and skill development programs.

- Health and wellness benefits.

- Exposure to innovative and high-impact 3D web projects.
