Backend Developer Intern

About Sarwagyna

Sarwagyna Private Limited is an Andhra Pradesh based technology company building AI products for Indian businesses. Our current focus is SvaraCall AI — an AI voice calling agent platform that automates outbound and inbound business conversations using real-time speech AI and large language models. The platform has completed its pilot phase and is now entering production engineering, covering reliability hardening, scale, and inference cost optimisation. The product is presented at svaracall.sarwagyna.com. We are recruiting a cohort of software engineering interns to work directly with the founding engineering team on this transition. Interns will ship code to a live platform rather than work on isolated training exercises.
