Job Description
Principal Graphics Engineer
Location: Bengaluru, India
About i Merit
i Merit is a global leader in AI data solutions, trusted by the world’s most innovative companies to power mission-critical AI initiatives. Our platforms, Ango Workflow Automation and 3 D Point Cloud Multi-Sensor Fusion, power data pipelines for some of the world’s most advanced Autonomous Vehicle (AV), Robotics, and Mobility programs.
We are building a next-generation annotation platform designed for AV and ADAS applications. It unifies large-scale data ingestion, workflow orchestration, AI-assisted annotation, and high performance visualization into a seamless, real-time web environment that handles complex multi-sensor and multi-modal data sources.
About the Role
We are seeking a highly skilled and motivated Principal Graphics Engineer to lead the design and optimization of a high-performance, browser-based visualization engine for multi-sensor data annotation. You will architect GPU pipelines that deliver real-time 3 D rendering for Li DAR, RADAR, and video data, and drive innovation in how users visualize, edit, and validate complex 3 D environments.
This is a principal-level, hands-on engineering role that also influences technical strategy, design direction, and mentorship within the graphics and visualization team.
Key Responsibilities
- Design: Architect and optimize Web GPU/Web GL rendering pipelines for large-scale point clouds and sensor-fusion visualization.
- Performance Optimization: Lead the optimization efforts for rendering massive 3 D point clouds (millions of points) in real-time usingtechniques like frustumculling, level- of-detail (LOD), spatial partitioning (e.g., octrees/k-d trees), and instancing.
- Shader Development: Design, write, and maintain high-performance, complex GLSL/WGSL shadersfor both rendering and compute tasks (e.g., color mapping, depth processing, data manipulation, and custom visualization effects).
- API Mastery: Serve as the subject matterexpert for three.js, Web GL 2.0, and the emerging Web GPU standard.
- Geometry Management: Expertly manipulate and optimize three.js Primitives (e.g., Box Geometry, Points, Line Segments) for memory efficiency and rendering speed, especially when dealing with dynamic annotation tools.
- Real-Time Processing: Implement on-device data processing, filtering, and
transformation logic directlywithin the GPU compute pipeline, minimizing CPU overhead
- Code Quality& Architecture: Establish best practices for 3 D rendering code, conduct code reviews, and mentor junior developers.
Qualifications
- 6–10 years of experience building GPU-accelerated graphicsapplications around Typescript/Javascript.
- Proficiency in GLSL shader programming, Web GL 2.0 and Web GPU.
- Expert-level proficiency with three.js and extensiveexperience writing custom, performant rendering logic.
- Deep understanding of 3 D mathematics, camera models, and real-time rendering pipelines.
- Mastery of three.js geometricprimitives including efficient use of Buffer Geometry, attribute buffers, and techniques for instanced rendering.
- Experience optimizing performance bottlenecks in CPU/GPU rendering pipelines.
- Strong communication and collaboration skills, with a proven abilityto mentor othersand influence design decisions.
Additional Qualifications
- Experience with point-cloud libraries (Potree, Open3 D, PCL).
- Understanding of multi-sensor data synchronization and streaming architectures.
- Familiarity with CI/CD pipelines and containerization (Docker, Kubernetes).
- Awareness of distributed systemsor backend data services supporting visualization.
Why Join Us?
At i Merit, you will define how the world’s most advanced autonomous systems perceive and understand their surroundings. You will own the core visualization experience used by global industry leaders and push the boundaries of real-time GPU rendering in the browser.
Your work will directlyinfluence how AI engineers, annotators, and customers see and interact with data, turning complex 3 D sensor streams into intuitive visual insight. Join us to build the visualization engine powering the next generation of autonomy and intelligent perception.
