RevRag AI is an emerging AI‑driven startup focused on building voice‑enabled assistants and in‑app AI agents that transform how users interact with digital products. Founded by a team of seasoned engineers and AI researchers, the company combines deep expertise in natural language processing, large language models, and scalable backend infrastructure to deliver real‑time conversational experiences. Operating from a remote‑first model, RevRag AI attracts talent across India, offering a collaborative culture where every engineer’s contribution directly impacts product performance and user satisfaction. As a Software Developer Intern (Backend), you will join the core engineering team and work on production‑grade services that power the company’s voice and AI platforms. This is not a sandbox project; you will write, test, and ship code that runs for real customers. You will gain hands‑on experience with modern Python frameworks, cloud deployments, and data pipelines while collaborating with senior engineers, product managers, and AI scientists. The internship is designed to accelerate your learning curve, giving you ownership of meaningful features and exposure to the full software development lifecycle in a high‑growth startup. **Key Responsibilities** 1. Design, develop, and enhance backend APIs and micro‑services using Python frameworks such as FastAPI, Flask, or Django. 2. Implement data models, write efficient SQL queries, and integrate with databases like PostgreSQL or MySQL. 3. Build and maintain integrations with external services, including cloud storage, messaging queues, and AI inference endpoints. 4. Write clean, testable, and production‑ready code with unit and integration tests. 5. Debug, troubleshoot, and resolve production issues to improve system reliability. 6. Participate in code reviews, contribute to architectural discussions, and follow best practices for version control and CI/CD. 7. Document APIs, design decisions, and deployment procedures for internal consumption. 8. Assist in setting up containerized environments using Docker and orchestrate deployments on cloud platforms (AWS/GCP). 9. Collaborate with the AI team to expose model inference results through RESTful endpoints. 10. Contribute to internal tooling that streamlines developer workflows and monitoring. **Tech Stack**: Python, FastAPI/Flask/Django, REST APIs, PostgreSQL/MySQL, Docker, Git, AWS (or GCP), CI/CD pipelines. **Growth Path**: Successful interns can transition to full‑time Software Engineer roles, gaining deeper responsibilities such as leading service design, owning critical product modules, and eventually moving into senior or lead engineering positions. The startup environment offers rapid skill acquisition, mentorship from seasoned engineers, and visibility across product and business functions. **Why Join RevRag AI?** - Direct impact: Your code powers live AI products used by thousands of users. - Learning at scale: Work with cutting‑edge voice AI technologies and modern backend architectures. - Mentorship: Close interaction with senior engineers and AI researchers accelerates professional growth. - Flexible remote work: Balance productivity with personal commitments while staying connected to a vibrant engineering community. - Startup culture: Fast‑paced, merit‑based, and open to innovative ideas, giving you space to experiment and lead.
