Senior Data Scientist

Overview

Lead research, analysis and development of advanced text-to-video and image-to-video generation models to improve JioStar's content production and drive measurable gains in user engagement, satisfaction and retention.

What you'll do

• Design, prototype and refine deep learning models for text-to-video and image-to-video generation using generative AI techniques (e.g., diffusion models, transformers, temporal GANs).
• Collaborate with 3rd-party AI vendors to evaluate their capabilities, run quality benchmarks and drive technical integration where applicable.
• Lead the creation of in-house solutions to augment 3rd-party offerings, focusing on video quality, generation time and content relevance.
• Develop robust pipelines for dataset curation, preprocessing, training and model evaluation, including automated visual, temporal and semantic quality metrics.
• Work closely with product managers, engineering teams and senior leadership to define use cases, set priorities and bring production-grade AI systems to life.
• Run A/B tests, iterate based on performance feedback and ensure alignment with product experience goals and creative quality standards.
• Stay ahead of the GenAI space, guide strategy, share insights internally and represent the team in technical forums as needed.

What you'll need

• Proven experience with deep learning architectures for generative tasks (e.g., diffusion models, transformers, GANs).
• Strong understanding of LLMs, with hands-on experience in fine-tuning, prompt engineering and evaluating foundation models for applied multimodal generation use-cases.
• Strong exposure to ML evaluation techniques, including perceptual quality metrics and user-in-the-loop testing.
• Proficiency in Python, R and SQL.
• Experience with big data technologies (e.g., Hadoop, Spark) and cloud platforms (e.g., AWS, Google Cloud).
• Excellent verbal and written communication skills, with the ability to present complex information to non-technical stakeholders.
• Master's or PhD in Computer Science, Statistics, Mathematics or related quantitative field, with 4+ years of hands-on experience in data science, the last few years working with the GenAI stack, especially audio and video modalities.

Nice to have
