Senior Gen AI Engineer - Nagarro
AI Engineer
Senior Gen‑AI Engineer responsible for designing and scaling Python‑based APIs with FastAPI, building production‑grade LLM applications using OpenAI and Anthropic, and implementing end‑to‑end Retrieval‑Augmented Generation (RAG) solutions with vector databases and semantic search.
About the role
- Design, develop, and maintain scalable Python-based APIs and backend services using FastAPI and related frameworks.
- Build, deploy, and optimize production-grade LLM applications using providers such as OpenAI and Anthropic.
- Design and implement end-to-end RAG solutions, including vector databases, semantic search, retrieval optimization, and chunking strategies.
- Develop and manage secure, scalable MCP servers and AI infrastructure.
- Build and orchestrate multi-agent systems to automate complex workflows and business processes.
- Create, test, and refine prompts, agent instructions, and LLM interactions to improve solution quality and performance.
- Leverage AI-assisted development tools (e.g., Claude Code, Cursor, GitHub Copilot) to accelerate software delivery and engineering efficiency.
- Implement event-driven architectures, messaging systems, and real-time communication patterns.
- Monitor, troubleshoot, and optimize AI and backend systems for performance, reliability, scalability, and security.
- Collaborate with cross-functional teams to deliver innovative AI solutions and establish engineering best practices.
- 8+ years of experience developing APIs with Python
- 2+ years of experience developing and experimenting with LLMs
- Hands-on, daily use of AI-assisted and agentic coding tools (e.g., Claude Code, Cursor, GitHub Copilot, autonomous coding agents) to write and refactor code, automate workflows, and optimize engineering processes.
- Strong experience with Python, particularly in building REST APIs using frameworks like FastAPI.
- Grounding in NLP and machine learning as they relate to building LLM systems
- Strong experience working with key LLM models APIs (e.g. OpenAI, Anthropic)
- Experience building, deploying, and securing MCP servers at scale.
- Understanding of multi-agent systems and their applications in complex problem-solving scenarios.
- Designing and implementing RAG systems end to end: vector databases, semantic search, retrieval quality, and chunking strategy.
- Experience with prompt writing for various use cases
- Experience with generative solutions released to prod, at scale, beyond POCs
- Proficiency with server-side events, event-driven architectures, and messaging systems.
- Strong critical thinking and systems thinking skills, with experience debugging, optimizing, and making sound engineering decisions across complex backend systems, not just solving isolated problems.
- Solid understanding of security best practices for backend systems, including authentication and data protection.
Nice-to-have skills:
- Experience with LLM guardrails
- Experience with LLM Frameworks (e.g. LangChain, LlamaIndex)
- Experience with LLM monitoring and observability
- Experience developing AI/ML technologies within large and
