Senior ML / AI Engineer (LLMs & Agentic AI)

Location: Belfast (Hybrid, 2-days a week in office)

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
