AI Engineer (LLM, GenAI & Agentic Systems)

The ideal candidate is an AI engineer who can build and deploy real-world LLM and GenAI solutions. Experience delivering AI applications, agentic systems, RAG solutions, and AI-assisted engineering practices will be weighted more heavily than frontend framework expertise

About the Role

We are seeking a talented AI Software Engineer (LLM, GenAI & Agentic Systems) to join our growing AI Engineering team. This role focuses on designing, building, and deploying production-grade AI solutions that leverage Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), agentic workflows, and AI-assisted software engineering practices.

You will work closely with solution architects, product teams, data scientists, and clients to transform AI concepts into scalable, secure, and business-ready applications. Beyond writing high-quality software, you will play a key role in shaping how AI technologies are applied responsibly and effectively across enterprise environments.

• Package and deploy AI applications using containerisation technologies such as Docker.
• Collaborate with DevOps teams to deploy AI services into cloud and enterprise environments.
• Implement application logging, monitoring, observability, and AI performance telemetry.
• Support production deployments and troubleshoot operational issues.

Collaboration & Knowledge Sharing

• Work closely with business stakeholders, product managers, architects, and data scientists.
• Contribute to solution design workshops, proofs of concept, and client demonstrations.
• Share best practices and mentor team members on AI engineering methodologies.
• Create reusable assets, templates, reference implementations, and technical documentation.

Required Qualifications

• Bachelor's Degree, Master's Degree or equivalent practical experience in Computer Science, Information Technology, Engineering, Data Science, or related disciplines.
• 3+ years of professional software development, AI engineering, automation engineering, or related experience.
