  • Implement and operate observability tooling using:

    • OpenTelemetry for distributed tracing

    • Metrics and dashboards (Prometheus, Grafana)

    • Logs and analytics (ELK or equivalent)

  • Define and track ML-specific reliability signals, such as:

    • Model performance degradation

    • Data drift and feature anomalies

    • Prediction latency and failure rates

  • Establish SLOs and alerting strategies for ML services in production.

Testing, Validation & Responsible AI Enablement

  • Ensure testing and validation are embedded throughout the ML lifecycle, including:

    • Model validation and regression testing

    • Data and feature consistency checks

    • Deployment verification and rollback testing

  • Integrate automated ML testing and quality gates into CI/CD pipelines.

  • Support non-functional testing for ML systems, including:

    • Performance and scalability testing

  • Partner with AI, data, and compliance teams to support responsible and compliant AI operations, including auditability, traceability, and explainability hooks (where required).

AI Platform Enablement & Cross‑Team Collaboration

  • Enable data scientists and ML engineers to move models from experimentation to production efficiently and safely.

  • Provide reusable tooling, templates, and paved paths for:

    • Experiment tracking

    • Model registry usage

    • Deployment and monitoring patterns

  • Collaborate closely with:

    • Infrastructure Engineering (runtime, scaling, security)

    • DataOps Engineering (data pipelines, feature stores, data quality)

    • Product and analytics leaders to align ML capabilities to business outcomes

Reliability, Incident Management & Continuous Improvement

  • Own operational reliability for ML platforms and services.

  • Lead response to ML-related production incidents, including:

    • Model failures or degradations

    • Data drift–driven issues
