About the Role: Power BI Developer

Are you a skilled data professional looking to deploy enterprise analytics for critical infrastructure systems? Tata Power is hiring a full-time, permanent Power BI Developer to join its growing analytics squad in Odisha, India. This role is designed for mid-level professionals with 3 to 6 years of experience (with a core expectation of 4+ years of strong, hands-on dashboard expertise) who hold a B.Tech/B.E. degree in Computer Science and Engineering.
