Base pay range: Direct message the job poster from ViVA Tech Talent

The Role: Join a high-impact AI/ML team building production-grade systems using Large Language Models, RAG, and agentic AI frameworks. Design intelligent workflows that turn large-scale, noisy, unstructured data into actionable insights used by analysts and customers in real time.

What You’ll Do

• Build and fine-tune LLM-powered systems for reasoning, orchestration, and decision-making
• Design agentic workflows using modern frameworks (e.g. LangGraph / LangChain)
• Develop RAG pipelines, vector search, and semantic retrieval at scale
• Architect and ship production ML services and APIs
• Own deployment, monitoring, evaluation, and optimisation (accuracy, latency, cost)
• Work closely with product and domain experts to deliver real-world impact

What You Bring

• Strong Python and production ML experience (PyTorch or TensorFlow)
• Hands-on experience with LLMs, prompt engineering, fine-tuning, and agent frameworks
• Deep knowledge of RAG, vector databases, and embeddings
• Experience with LLMOps / MLOps, observability, and evaluation
• Solid background in distributed systems, microservices, and streaming data
• Cloud & infrastructure experience (Docker, Terraform, AWS or similar)
• Experience with large-scale unstructured data; security, intelligence, or OSINT is a plus
• Hybrid working (Belfast-based office + remote)
• Modern engineering stack and strong focus on production quality AI
• High autonomy, real-world problems, and meaningful impact

Working pattern

• Hybrid: 2 day per week in Belfast office, 3 days remote

Package

• Bonus
