With 6,000+ experts worldwide, we combine engineering expertise with AI-native thinking to turn ambitious ideas into real-world impact across industries, technologies, and markets.\nAt the core of the role\nWe're looking for a Senior AI Engineer / ML Engineer to join an R&D team building next-generation AI solutions based on Large Language Models and agentic AI.\nThis is not a traditional ML engineering role. You'll work on rapidly evolving AI products, combining modern LLM capabilities with strong Machine Learning fundamentals to design production-ready solutions. You'll be expected to evaluate business problems, choose appropriate ML approaches, architect end-to-end systems, and independently drive ideas from concept to deployment.\nIf you enjoy solving complex engineering problems around LLMs and agentic AI, experimenting with new technologies, and turning research into practical products, we'd love to hear from you.\nYou'll join a senior AI engineering team working in a fast-moving R&D environment where experimentation, ownership, and rapid iteration are part of everyday work.\nThe team designs and delivers production AI systems based on LLMs, agentic workflows, and modern Machine Learning techniques. Engineers are expected to take ownership of technical decisions, collaborate closely with architects and product stakeholders, and continuously evaluate new approaches as the technology evolves.\nThis role offers the opportunity to work on cutting-edge AI products while having a real impact on both technical direction and product design.\n\nCore skills you’ll bring\n6+ years of commercial experience building Machine Learning systems.\n\nProven ML technical leadership experience - the ability to understand business problems, select appropriate ML approaches, design end-to-end solutions, and make technical decisions beyond simply implementing models.\n\nStrong hands-on experience with agentic orchestration frameworks such as LangGraph, LangChain, or similar.\n\nExperience designing multi-agent systems, orchestration workflows, state management, tool calling, and structured outputs.\n\nHands-on experience building production-grade applications using Large Language Models (OpenAI, Gemini, Anthropic or similar).\n\nStrong understanding of:\nRetrieval-Augmented Generation (RAG)\n\nembeddings\n\nsemantic search\n\nretrieval optimization\n\nprompt engineering and context management\n\nExperience working with vector databases (Vertex AI RAG Engine, Pinecone, FAISS, Weaviate or similar).\n\nStrong Python development skills.\n\nExperience building APIs with FastAPI (or similar frameworks).\n\nExperience with async programming and long-running backend processes.\n\nExperience designing structured data models using Pydantic (or similar validation frameworks).\n\nExperience with Docker.\n\nComfortable working independently in fast-changing R&D and Proof-of-Concept environments.\n\nStrong ownership mindset and excellent problem-solving skills.\n\nExperience using AI-assisted development tools for coding, debugging, refactoring, and documentation.\n\nNice-to-have:\nExperience with Google Cloud Platform.\n\nHands-on experience with Vertex AI and Gemini.\n\nExperience with Vertex AI RAG Engine.\n\nExperience with AWS or Azure and willingness to work with GCP.\n\nExperience combining LLMs with Computer Vision, signal processing, or other multimodal AI systems.\n\nExperience fine-tuning foundation models or adapting open-source LLMs.\n\nExperience designing evaluation and benchmarking pipelines for AI systems.\n\nThe impact you'll create\nDesign end-to-end AI solutions by analysing business problems, selecting appropriate Machine Learning approaches, and defining scalable system architectures.\n\nBuild production-grade agentic AI systems using modern orchestration frameworks and Large Language Models.\n\nDevelop and improve Retrieval-Augmented Generation (RAG) pipelines, semantic search, and knowledge retrieval solutions.\n\nDesign and implement robust Python backend services and APIs supporting AI applications.\n\nCollaborate with engineering and product teams to rapidly prototype, validate, and iterate on new AI capabilities.\n\nEvaluate new technologies, frameworks, and research directions, translating promising ideas into production-ready solutions.\n\nDrive technical quality, reliability, and maintainability across AI systems while contributing to architectural decisions and engineering best practices.\n\n What supports your journey\nThrough our values, we strive to provide you with the tools, autonomy, trust, and assistance you need to excel. Enjoy benefits like private health insurance, well-being programs, flexible and hybrid work models, laptops and gear, training, language classes, social events, great offices, and more.\nPeople are at the core of Avenga.
