Job Summary: As a Senior Data Scientist with expertise in the GenAI stack (audio & video generation models), you will lead the research, analysis, and development of advanced video generation models to enhance JioStar’s current and prospective content production. This initiative aims to achieve quantifiable improvements in user engagement, satisfaction, and retention, driven by data-driven innovations.
About the team:
We’re an AI native, agile & fast-moving team focused on turning bold ideas into impactful products. From rapid prototyping of new concepts to building scalable platforms that power future growth, we thrive on experimentation and innovation. Our platform highlights creators and their narratives by giving them AI-powered systems using advanced machine learning and multimedia pipelines. As part of this team, you’ll work at the intersection of creativity and technology — building end-to-end experiences, experimenting with emerging tech, and shaping the future of entertainment content.
Key responsibilities:
- Design, prototype, and refine deep learning models for text-to-video and image-to-video generation using cutting-edge techniques in generative AI (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, with a focus on improving 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 curve in the fast-moving GenAI space; guide strategy, share insights internally, and represent the team in technical forums as needed
Skills and attributes for success:
- 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 use-cases for multimodal generation
- Preferred understanding of computer vision, natural language processing, and multimodal learning
- Strong exposure to ML evaluation techniques, including perceptual quality metrics and user-in-the-loop testing
- Proficiency in programming languages such as 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.
Preferred education and experience:
Master's or PhD in Computer Science, Statistics, Mathematics, or related quantitative field with 4+ years of hands-on experience in data science, with last few years working with GenAI stack, especially audio & video modalities
