Key Responsibilities:

• Build and deploy prototypes that deliver real business or research value.
• Lead model experimentation, evaluation, and creative prototyping.
• Implement and extend recent AI/ML research into functional systems.
• Operate across the stack: data pipelines, model training, API development, and intuitive interfaces.
• Introduce new tools, frameworks, and research directions to the team.
• Foster a culture of speed, curiosity, and experimentation.
• Enjoy autonomy, ownership, and creative freedom—your ideas will have visible impact.
