We are looking for a Business-as-Usual (BAU) Engineer with a strong automation and AI mindset to join our AWS BAU team. This role is critical to ensuring stable day-to-day operations while leading the adoption of AI-driven automation and operational intelligence across our cloud estate.

The successful candidate will combine hands-on BAU operational expertise with the ability to identify, design, and deliver automation opportunities using AI, scripting, and cloud-native tooling, helping the team move from reactive operations to proactive, self-healing services.
