We are seeking an Manager, AI Ops Site Reliability Engineer to own how our operations agents think and how well they perform, within Hosting SRE Operations, based in Greece. In this role, you design the agent workflows, prompts and context, build the evaluation harness that proves accuracy against our own estate, and partner with our existing domain experts to convert their operational know-how into reliable, measurable agent behavior. You bring depth in AI and evaluation; our domain specialists bring the deep OS, Storage, Data Protection, Database and HCI knowledge - together you turn classic operations into trustworthy AI operations.

Design agent workflows for intake and investigation: the prompts, context and retrieval, tool selection and decision logic that determine how the agent classifies, enriches and reasons about incidents.

Build and own the evaluation harness: ground-truth datasets drawn from historical incidents, accuracy, precision and recall metrics, regression tests, and hallucination and error detection - so every change to an agent is measured before it ships.

Define the reasoning guardrails: what an agent may conclude and propose, how confident it must be, and when it must defer to a human - the quality side of the approval gate.

Turn tacit operational knowledge into machine-usable context: work with the existing domain experts to convert their runbooks and past investigations into retrievable knowledge the agent can cite.
