About the Role We are seeking a talented and driven mid-level Backend Software Engineer to join our foundational team in Bangalore. This is not just a coding role; you will be a critical part of our AI engine room, responsible for designing, building, and scaling the complex backend systems that power our Retrieval-Augmented Generation (RAG) solutions. You will tackle challenges in advanced retrieval, context engineering, and long-running asynchronous processing, directly impacting our platform's intelligence and performance. As an early member of the team, you will have significant ownership and a clear path for growth into a leadership position. What You'll Do: Design, develop, and maintain robust and scalable backend services using Python and FastAPI. Architect and implement production-grade Retrieval-Augmented Generation (RAG) pipelines for our core proposal generation engine. Build and manage complex, long-running asynchronous workflows (e.g., multi-document analysis, compliance report generation) using Azure Function Apps , particularly leveraging orchestrators and activity functions (Durable Functions). Work extensively with our database stack, including MongoDB for application data and Qdrant for vector search and retrieval. Implement and refine techniques in prompt engineering, context engineering, and advanced retrieval to improve the quality and relevance of our AI-generated content. Collaborate closely with a small, cross-functional team to define features, solve problems, and deliver high-quality solutions. Take full ownership of features from conception to deployment, embodying a product-first mindset to ensure our solutions effectively solve customer problems. Who You Are (Required Qualifications): 3+ years of professional software engineering experience, with a strong focus on backend development. 1+ year of hands-on, production-level experience building and deploying applications powered by Generative AI (specifically with RAG architectures). Strong proficiency in Python and experience building APIs with frameworks like FastAPI (or Django/Flask). Demonstrable, in-depth experience with Azure Function Apps for creating complex, stateful, and asynchronous workflows. This is a must-have skill. Practical experience working with both NoSQL databases (e.g., MongoDB ) and vector databases (e.g., Qdrant , Pinecone, Weaviate). Experience integrating with third-party LLM APIs (e.g., Azure OpenAI, Google Gemini/PaLM). Excellent problem-solving skills and a strong foundation in data structures and system design. A strong sense of ownership, adaptability, and a product-first mindset. You're motivated by seeing your work solve real-world problems. Must be based in or willing to relocate to Bangalore. Nice-to-Haves (Preferred Qualifications): Familiarity with AI frameworks like LangChain or LangGraph. Experience with building AI agents or multi-agent systems. Prior experience working in a fast-paced startup environment. An interest in mentoring junior engineers and growing into a technical leadership role. Why Join Us? Impactful Work: Be a core contributor to a cutting-edge AI product that is transforming an entire industry.
