Business-as-Usual (BAU) Engineer with Automation and AI Mindset

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.

Key Responsibilities

BAU & Operational Excellence

  • Own and execute day-to-day BAU operations, including system monitoring, incident resolution, patching, and routine maintenance.
  • Troubleshoot and resolve issues across Linux servers, AWS infrastructure, applications, and networking layers.
  • Ensure adherence to SLAs, ITSM processes (Incident, Change, Problem), and operational controls.
  • Perform root cause analysis (RCA) and implement long-term corrective and preventive actions.
  • Support scheduled maintenance, upgrades, certificate renewals, and capacity planning.
  • Maintain high-quality documentation, runbooks, SOPs, and knowledge articles.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
