Lead AIML Engineer– 3D Mannequin & Virtual Fitting Room

We’re hiring a lead, full-stack AIML & Python Engineer to independently build and deliver a complete 3D mannequin system powered by AI and computer vision.

You will lead the end-to-end development of an intelligent virtual fitting solution that takes user video as input, reconstructs accurate body mannequins (including full measurements and circumferences), applies designed garments, and presents them in different poses and scenes — with seamless integration into AR platforms.

Role: AI-Machine Learning Engineer (3D Graphics Specialist)

Experience: 3+ years in Machine Learning, Computer Vision, and 3D Graphics Development.

We are seeking a highly skilled and innovative Machine Learning Engineer with 3D Graphics expertise. In this role, you will be responsible for developing and optimising 3D models using machine learning algorithms, computer vision techniques, and 3D rendering tools. You will collaborate with backend developers, data scientists, and UI/UX designers to create realistic, scalable, and interactive 3D visualisation modules that enhance the user experience.

Key Responsibilities:

3D Model Development:

- Design and develop 3D models using ML-based body shape estimation.
- Implement pose estimation, texture mapping, and deformation models.
- Use ML algorithms to adjust measurements for accurate sizing and fit.

Machine Learning & Computer Vision:

- Develop and fine-tune ML models for body shape recognition, segmentation, and fitting.
- Implement pose detection algorithms using TensorFlow, PyTorch, or OpenCV.
- Use GANs or CNNs for realistic 3D texture generation.

3D Graphics & Visualization:

- Create interactive 3D rendering pipelines using Three.js, Babylon.js, or Unity.
- Optimise mesh processing, lighting, and shading for real-time rendering.
- Use GPU-accelerated techniques for rendering efficiency.

Model Optimization & Performance:

- Optimise inference pipelines for faster real-time rendering.
- Implement multi-threading and parallel processing for high performance.
- Utilise cloud infrastructure (AWS/GCP) for distributed model training and inference.

Collaboration & Documentation:

- Collaborate with UI/UX designers for seamless integration of 3D models into the web and mobile apps.
- Maintain detailed documentation for model architecture,



training processes, and rendering techniques.

Key Skills & Qualifications:

Technical Skills:

- Proficiency in Django, Python, TensorFlow, PyTorch, and OpenCV.
- Strong expertise in 3D rendering frameworks: Three.js, Babylon.js, or Unity.
- Experience with 3D model formats (GLTF, OBJ, FBX).
- Familiarity with Mesh Recovery, PyMAF, and SMPL models.

ML & Data Skills:

- Hands-on experience with GANs, CNNs, and RNNs for texture and pattern generation.
- Experience with 3D pose estimation and body measurement algorithms.

Cloud & Infrastructure:

- Experience with AWS (SageMaker, Lambda) or GCP (Vertex AI, Cloud Run).
- Knowledge of Docker and Kubernetes for model deployment.

Graphics & Visualisation:

- Knowledge of 3D rendering engines with shader programming.
- Experience in optimisation techniques for rendering large 3D models.

Soft Skills:

- Strong problem-solving skills and attention to detail.
- Excellent collaboration and communication skills.
