For more information, please visit http://www.ixigo.com\n We are looking for a Senior Backend Engineer with strong backend engineering skills and experience with AI engineering . You should be comfortable working across the stack, but your core strength should be building scalable backend systems, APIs, and AI-powered product features. You will own features end-to-end, from architecture and development to deployment, monitoring, and support.\nRoles & Responsibilities\nDesign and build backend systems that power real-time, low-latency AI experiences and distributed systems\n\nBuild AI-powered features and production-grade agentic workflows.\n\nBuild async and event-driven systems using queues, workers, WebSockets, or streaming\n\nBuild and evolve conversational AI systems: dialogue management, context handling, intent routing, fallback design\n\nOwn the infra behind AI features: streaming responses, WebSocket/SSE pipelines, queue-based orchestration\n\nMake product-level decisions: you’ll have opinions on what to build, not just how to build it\n\nWork on voice-enabled systems (STT/TTS, streaming APIs) as part of end-user experiences\n\nDeploy and operate services with a focus on low latency, high availability, and robustness\n\nInstrument, monitor, and improve AI systems in production (eval frameworks,

architecture\n\nStrong understanding of databases, caching, async processing, and system design\n\nExperience integrating LLMs and building Agentic AI powered products\n\nHands-on experience building with LLMs: prompt engineering, function/tool calling, RAG, embeddings, fine-tuning awareness\n\nExperience in building AI-driven products, voice and conversational experiences\n\nStrong systems design instincts, with a practical mindset for navigating technical tradeoffs\n\nProduct thinking: you understand why you’re building something, not just the ticket description\n\nComfort with ambiguity: AI product development is fast, iterative, and occasionally chaotic\n\nStrong Signals\nBuilt or shipped AI products (voice or text chatbots, copilots, assistants)\n\nExperience designing evaluation and feedback loops for AI systems\n\nOpen-source contributions or strong personal projects\n\nWhat We Value\nAI-native engineering mindset with full-stack execution ability\n\nStrong ownership and ability to drive projects independently\n\nCuriosity for AI and modern engineering practices\n\nClear communication and comfort working in a fast-paced startup environment\n\n Responsible for safeguarding
