Data Scientist (Gen AI)

We’re seeking a highly skilled, hands-on Data Scientist with 4–10 years of experience in applied AI / ML to join our fast-paced team. This role requires deep expertise in transformer architectures and strong fundamentals in model training, fine-tuning, and optimization. You’ll work across modalities (text, audio, video), with the flexibility to specialize in one domain but the adaptability to experiment across others.

The ideal candidate thrives in a startup-style, high-velocity R&D environment, is execution-focused, and demonstrates ownership from architecture to deployment. You’ll run rapid experiments, iterate on state-of-the-art models, and push the boundaries of generative AI in lip-sync, character consistency, audio realism, and video quality — with a research-first, problem-solving mindset.

Responsibilities

• Model Development & Fine-tuning : Run end-to-end experiments on transformer-based architectures (LLMs, Whisper, diffusion, LoRA, RLHF / SFT, multimodal models).
• Domain-Specific Applications :
• Audio : Lip-sync, emotional delivery (shouting, whispering, crying), regional language support.
• Video : Scene / character consistency, quality benchmarks comparable to Veo3 / Sora.
• Text : Extend LLMs to handle regional languages and domain-specific adaptation.
• Evaluation & Optimization : Design automated evaluation frameworks for objective quality scoring (images, video frames, audio clips). Balance trade-offs in speed, quality, and efficiency.
• Cross-Modality Integration : Experiment with audio-video synchronization, background score integration, and text-to-video alignment.
• Research & Experimentation : Stay ahead of rapidly evolving models and tools, testing architectural variations and scaling solutions for production use.
• Ownership & Execution : Drive initiatives independently with strong problem-solving, accountability, and first-principles thinking.
