Senior / Staff AI Engineer

📍 Remote (Europe-based preferred) | Full-time | Permanent

My client is building a next-generation agentic AI platform designed to deliver autonomous, adaptive customer support at scale. The team is pioneering multi-agent systems that reason, plan, and act seamlessly without rigid scripting enabling enterprises to deliver real-time resolutions with minimal human intervention.

They are looking for a Senior or Staff AI Engineer to join our fast-growing AI division. This role will suit someone who thrives at the intersection of software engineering, applied machine learning, and cutting-edge generative AI research.

What you'll do

• Design, build, and deploy AI agent architectures capable of autonomous decision-making and task execution.

• Integrate foundation model endpoints (LLMs, speech-to-text, text-to-speech) into production systems.

• Develop RAG (retrieval-augmented generation) pipelines, vector databases, and knowledge integration layers.

• Collaborate with scientists, engineers, and product teams to turn research ideas into scalable features.

• Prototype rapidly, test hypotheses, and productionise robust systems with strong reliability.

• Contribute to the long-term technical vision for multi-agent systems in customer experience.

What we're looking for

• Strong background in machine learning, NLP, or AI systems engineering.

• Hands-on experience with large language models (LLMs), including fine-tuning and prompt engineering.

• Proven experience deploying production-grade ML systems (Python, FastAPI, cloud infrastructure).

• Familiarity with vector databases (e.g., Pinecone, Weaviate, FAISS, Qdrant) and embeddings.

• Knowledge of multi-agent orchestration frameworks (LangChain, AutoGen, Haystack, etc.).

• Ability to balance rapid prototyping with building scalable, reliable systems.

• Strong software engineering fundamentals and collaborative mindset.
