Senior AI Engineer

🚀 Senior AI / ML Engineer (LLMs & Agentic AI)

📍 Belfast / Hybrid

💸 £DOE plus bonus and fantastic benefits

We’re partnering with a fast-growing technology company operating at the intersection of AI and large-scale data. They are building next-generation AI systems that help transform vast amounts of unstructured information into actionable insights in real time.

This is an opportunity for an experienced Machine Learning Engineer to work on production-grade AI systems leveraging Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and agentic AI frameworks.

What You’ll Be Doing

• Design and deploy AI/ML systems using LLMs for reasoning, orchestration, and intelligent automation
• Build agent-based workflows coordinating complex tasks across multiple tools and data sources
• Develop scalable data pipelines capable of processing large-scale structured and unstructured datasets
• Create semantic search and retrieval systems using vector databases and embedding technologies
• Deliver production-ready APIs and microservices for real-time AI inference
• Improve model performance through evaluation, observability, prompt testing, and optimisation
• Collaborate closely with product, engineering, and intelligence teams to translate complex requirements into practical AI solutions

What We’re Looking For

• Strong Python engineering background with hands-on experience in PyTorch and/or TensorFlow
• Experience building production systems using LLM frameworks such as LangChain, LangGraph, AutoGen, or similar
• Expertise with RAG architectures, vector databases, embeddings, and semantic search
• Strong understanding of prompt engineering, fine-tuning, and foundation model integrations
• Experience with ML/LLMOps, monitoring, evaluation frameworks, and cost/performance optimisation
• Knowledge of distributed systems, microservices, streaming architectures, and cloud-native infrastructure
• Hands-on experience with Docker and infrastructure tooling such as Terraform or CloudFormation
• Ability to build scalable, reliable, and secure AI systems in production environments

What’s On Offer

• Opportunity to work on cutting-edge AI products with real-world impact
• Hybrid working environment with flexibility built into the culture
• Modern engineering stack and strong technical ownership
• Collaborative, mission-driven team environment
• Competitive compensation and benefits package

This role would suit someone who enjoys solving complex engineering problems, building scalable AI systems, and working on applied AI products beyond proof-of-concept stage.
