Senior Agent Operations & Evaluation Engineer​ #AIDA

About the role

About the Role

An engineering role that operates the live GenAI agents and builds the evaluation and observability that proves they are accurate, safe and improving.

On the operations side, keeps agents healthy, performs first-level triage and incident response, and minimises downtime.

On the evaluation and observability side, builds the operational dashboard for each use case, defines the metrics that matter, runs the evaluation suites, and proactively detects issues before customers do.

Works closely with the Day 1 build teams, solution architects and business owners across Singtel Singapore.

How You will Make An Impact:

• Build and maintain the operational observability dashboard for each AI / agent and Classical AI ML use case, across system health, performance, quality, safety and business-outcome metrics.
• Define, with build teams and solution architects (technical metrics) and product / business owners (outcome metrics), what needs to be measured per use case; consume the telemetry the platform provides.
• Build and run the evaluation suites (offline before launch and continuous evaluation on sampled production traffic after) and drive proactive detection of drift and quality decay.
• Monitor live agents, using the dashboards and automated safeguards, and act on alerts and proactive signals.
• Perform first-level triage and in-scope fixes (restart, safe-listed configuration, cache reset, routing fallback) per the runbooks.
• Manage incidents — classify severity, route by fault domain, escalate with a full evidence bundle, and verify-and-close in production — while owning the incident throughout.
• Contribute to the handover gate — verifying operability and evaluation evidence before an agent is accepted into full operation.
